Common Causes
The key image finding was ground-glass opacity in the lungs. Ground-glass opacity is a type of lung damage that can be caused by the partial filling of air spaces, increased capillary blood volume, the partial collapse of alveoli (the tiny air sacs of the lungs).
Related Conditions
Lung injury associated with vaping — the use of electronic nicotine delivery systems (ENDS) — has been recognized in the medical literature, 1,2 and a case series of such injuries is now published in the Journal. 3 If vaping is the proximal cause of lung injury, the mechanism leading to such injury is not certain.
What is ground glass opacity in the lungs?
We have not observed the computed tomographic finding of fat attenuation in the lung, which is a hallmark of lipoid pneumonia, in these cases of vaping-associated lung injury.
Can vaping cause lung injury?
Ground-glass opacification/opacity (GGO) is a descriptive term referring to an area of increased attenuation in the lung on computed tomography (CT) with preserved bronchial and vascular markings. It is a non-specific sign with a wide etiology including infection, chronic interstitial disease and acute alveolar disease. Article:

What is ground glass opacification on CT?
Can a chest xray show if you vape?
Chest CTs and X-rays highlight characteristics of EVALI in teens. Chest images collected from teen-agers who use e-cigarettes or vape share similar characteristics and can help speed up the diagnosis of lung injuries associated with those activities, according to a new study out today.
Do CT scans show if you vape?
Identified patterns can be used to make more accurate diagnoses and, potentially, avoid unnecessary biopsies.
How do you get ground-glass in your lungs?
This pattern occurs when the air in the lungs is replaced with fluid, inflammation, or damaged tissue. Nodular: This type can indicate both benign and malignant conditions. GGO that persists over several scans may indicate either premalignant or malignant growths.
What does vaping do to your lungs?
Vaping and Popcorn Lung Diacetyl is frequently added to flavored e-liquid to enhance the taste. Inhaling diacetyl causes inflammation and may lead to permanent scarring in the smallest branches of the airways — popcorn lung — which makes breathing difficult. Popcorn lung has no lasting treatment.
Does vaping put glass in your lungs?
Recognized patterns include ground glass opacity and consolidation. Injuries to the lungs from vaping have suggestive patterns on CT scans that could help physicians make accurate diagnoses and reduce unnecessary biopsies, according to a new study in Radiology: Cardiothoracic Imaging.
Can an MRI show if you vape?
In conclusion, short-term perfusion changes after use of electronic nicotine delivery systems and tobacco smoke exposure can be sensitively detected by functional MRI.
Should I be worried about ground glass opacity?
Ground-glass opacities are usually benign and resolve spontaneously without any complications in patients with short-term illnesses. Most of these patients may not even know that it is present. Others may complain of cough, tiredness, and shortness of breath.
What percentage of ground-glass opacities are cancerous?
Abstract: Pulmonary ground glass opacity (GGO) is becoming an important clinical dilemma in oncology as its diagnosis in clinical practice is increasing due to the introduction of low dose computed tomography (CT) scan and screening. The incidence of cancer in GGO has been reported as high as 63%.
What does ground glass opacity in lungs mean?
Ground-glass opacity (GGO) is a common finding on high resolution CT, characterised by areas of hazy increased attenuation of the lung with preservation of bronchial and vascular margins; it is not to be confused with consolidation, in which bronchovascular structures are obscured.
How long does vaping take to damage lungs?
Exposure for just three days was enough to incur sufficient damage to their lungs, setting the stage for long-term chronic lung damage.
How long after vaping do lungs heal?
After two weeks: your circulation and lung function begin to improve. After one to nine months: clear and deeper breathing gradually returns; you have less coughing and shortness of breath; you regain the ability to cough productively instead of hacking, which cleans your lungs and reduce your risk of infection.
What does vaping do to your heart?
2: Research suggests vaping is bad for your heart and lungs. It raises your blood pressure and spikes your adrenaline, which increases your heart rate and the likelihood of having a heart attack.
Can a doctor tell if you vape?
Medical tests can detect nicotine in people's urine, blood, saliva, hair, and nails. Nicotine is the addictive substance in tobacco, cigarettes, and vapes or e-cigarettes.
Can you smoke before a CT?
Do not eat, drink, or smoke anything at all for four hours before the exam. You may take any regular medications with a sip of water. Arrive at the hospital two hours before your CT is scheduled. Ask the scheduler what time that is.
Can you vape before PET scan?
No smoking or use of nicotine products for preferably 12 hours or at least four hours before arrival. If you take medication containing nicotine, let your PET/CT coordinator know immediately; call 206-215-6487.
How long does it take for nicotine to leave your system?
Generally, nicotine will leaves your blood within 1 to 3 days after you stop using tobacco, and cotinine will be gone after 1 to 10 days. Neither nicotine nor cotinine will be detectable in your urine after 3 to 4 days of stopping tobacco products.
What causes ground glass opacity?
Ground-glass opacity is a type of lung damage that can be caused by the partial filling of air spaces, increased capillary blood volume, the partial collapse of alveoli (the tiny air sacs of the lungs).
How many people vape in high school?
Vaping is on the rise: An estimated 5.4 million American middle and high school students vape. Scientists are racing to become better at diagnosing EVALI, the lung injury illness associated with vaping. More like this.
What causes EVALI?
E-cigarettes can contain a variety of chemical constituents that can harm the lungs. But it is vitamin E acetate that has emerged as the leading cause of EVALI. It is typically used to thicken THC oil and, in turn, is often found within black market vapes. An analysis published in The New England Journal of Medicine determined that vitamin E acetate was present in 48 out of 51 lung tissue samples from people with EVALI.
What percentage of Evali patients have reversed halo?
The CT scans, and not the chest X-rays, also revealed that 36 percent of the participants with EVALI had the “ reversed halo sign ” — an imaging descriptor that has been reported in association with a range of other pulmonary diseases, including pneumonia and tuberculosis.
How long did a 17 year old boy use e-cigarettes?
Radiological Society of North America. This CT scan of an axial lung window belongs to a 17-year-old boy. He used THC-containing e-cigarettes for two months until he experienced 8 days of nausea, vomiting, abdominal pain, and fever. Those symptoms were paired with subsequent chest pain and shortness of breath.
Can e-cigarettes cause evali?
E-cigarettes can contain a variety of chemical constituents that can harm the lungs. But it is vitamin E acetate that has emerged as the leading cause of EVALI. It is typically used to thicken THC oil and, in turn, is often found within black market vapes.
Do teens want to vape?
Teenagers still very much want to vape, despite the FDA’s attempt to make e-cigarettes look lame and researchers' efforts to prove vaping can harm the body. But a cache of new images might be enough to put some off their favorite habit. Vaping is on the rise: An estimated 5.4 million American middle and high school students vape.
What is an end vape?
ENDS, also known as E-cigarettes and vaping devices, were originally developed as a replacement device for conventional tobacco cigarette smokers [1]. However, their success in the arena of smoking cessation has been very limited, and they remain unapproved as cessation tools due to a lack of data demonstrating efficacy relative to currently approved nicotine replacement therapies [2]. The aerosols produced by E-cigarettes are known to cause a variety of deleterious health effects, although more research and long-term studies are still needed [2]. E-devices have rapidly evolved since entering the international market in 2013, with vape pens, box mods, and pod-based devices being the most commonly used vaping devices in 2020 [3]. Although E-cigarettes are used in conjunction with conventional tobacco by many cigarette smokers (dual users), their sole use in young adults and adolescents has skyrocketed [4]. This is concerning as use of tobacco products had been declining worldwide for over 50 years, and now, a new generation of nicotine addicts is being created through these novel vaping devices through the use of appealing flavors and packaging [5]. Even more concerning is that children and teenagers who use E-cigarettes are more likely to smoke conventional tobacco [6].
Does lung biopsy show tungsten?
Interestingly, energy-dispersive X-ray spectroscopy on the actual tissue samples failed to reveal evidence of tungsten or cobalt.
Is vaping a lung disease?
Although lung diseases caused by vaping have been reported since the modern invention of the electronic cigarette , in the summer of 2019, patients began to present to health care centers at epidemic levels with an acute respiratory illness relating to vaping, which the Center for Disease Control termed E-cigarette or vaping product use-associated lung injury (EVALI). This review discusses electronic nicotine delivery systems as well as the etiology, clinical presentation, imaging findings, pathologic features, treatment, and long-term consequences of EVALI. We conclude with the practical impact EVALI has had on the practice of pathology.
Is vaping a respiratory disease?
In the summer of 2019, an acute, mysterious, and deadly respiratory illness related to vaping emerged, primarily in young patients, in the USA. Cases increased dramatically and peaked in late September 2019. The Center for Disease Control and Prevention (CDC) termed the disease causing this epidemic E-cigarette or vaping product use-associated lung injury (EVALI). Prior to EVALI, vaping had been associated with a variety of different pulmonary presentations ranging from lipoid pneumonia to diffuse alveolar hemorrhage, but at low numbers. In this review, we discuss electronic nicotine delivery systems (ENDS) as well as the etiology, clinical presentation, imaging findings, pathologic features, treatment, and long-term consequences of EVALI. We conclude with a discussion on the practical impact EVALI has had on the practice of pathology.
What is the presentation of vaping associated lung disease?
Patients generally present with a combination of respiratory, gastrointestinal, and constitutional symptoms. Respiratory symptoms include shortness of breath, cough, chest pain, and occasionally hemoptysis. GI symptoms, including nausea, vomiting, diarrhea, and abdominal pain, occur in more than 80% of patients. Subjective fever is common (80%), but objective fever at triage is less so (29%). Other constitutional symptoms include chills, weight loss, fatigue, and headache. (Layden 2019)
How old is the average person who vapes?
The disease has predominantly affected young male patients. The average age in a recent large case series in the NEJM was 19, and 83% were males. There is a high rate of reported THC use (80%), which is a primary suspect as the underlying etiology. (Layden 2019)
Is vaping safer than smoking?
(Cullen 2018) When compared to smoking – one of the most unhealthy activities known – if would not be surprising if vaping resulted in fewer adverse health effects, although the true effects will not be known until we have long term studies. However, “ safer than cigarettes” is not the same as “safe”. When talking about smoking and vaping, we are usually focused on long term health outcomes. However, there has been a recent flood of case reports of young patients with significant lung disease after vaping. What is vaping associated lung disease and what do we need to know in the emergency department?
Is vaping a lung injury?
This isn’t the first time vaping associated lung injury has been reported. There are a number of prior case reports, dating back to 2012, with various underlying pathologies. (McCauley 2012; Flower 2017; Agustin 2018; Sommerfeld 2018; Viswam 2018; Arter 2019) Possible causes of this outbreak include chemical pneumonitis, acute eosinophilic pneumonia, acute and subacute hypersensitivity pneumonitis, lipoid pneumonia, metal fume fever, and polymer fume fever. (Christiani 2019; Layden 2019)
What is the inflammatory response to the presence of lipids within the alveolar space?
Lipoid pneumonia is an inflammatory response to the presence of lipids within the alveolar space and typically results from aspiration of hydrocarbons or oil-based products, but it has now been seen with vaping.
Can vaping cause lung injury?
3 If vaping is the proximal cause of lung injury, the mechanism leading to such injury is not certain.
Does vaping cause lung damage?
We have collectively seen 19 cases and reviewed the literature regarding another 15 cases. All met the case definition of vaping-associated lung injury, which includes “abnormalities on chest imaging.” We identified four imaging patterns that correlated with pathological findings attributable to vaping, including acute eosinophilic pneumonia, diffuse alveolar damage, organizing pneumonia, and lipoid pneumonia. In addition, some cases were associated with variegated imaging patterns. Through clinical and pathological investigations, patterns of giant-cell interstitial pneumonia, hypersensitivity pneumonitis, and diffuse alveolar hemorrhage were identified ( Figure 1; and see the Supplementary Appendix, available with the full text of this letter at NEJM.org).
VAPING - RELATED LUNG INJURIES
The CDC (Centers for Disease Control and Prevention) released a report on October 4th highlighting some facts about the recent outbreak of lung injuries related to vaping. The spate of hospitalizations appears to have started in July of 2019. As of October 1, 2019, there were 1,080 reported cases matching the CDC criteria and 18 deaths.
CDC CRITERIA FOR CONFIRMED & PROBABLE CASES OF VAPING - RELATED LUNG INJURY
According to the CDC, a confirmed case of Vaping-Related Lung Injury is defined as an individual that: (i) has vaped within the past 90 days, (ii) has pulmonary infiltrates which appear as ground-glass opacities on a CT scan, and (iii) has no infection, heart condition, or other disease that could explain respiratory distress.
SCIENTIFIC RESOURCES FOR VAPING - RELATED LUNG INJURIES
While hundreds of scientists are now urgently working to figure out the cause of these injuries, there are clinical case reports of these sorts of injuries going back to 2011. Below is a sampling of pertinent case articles and studies. We will keep you posted as new research emerges.
