Silent Vanishing Lung Syndrome: Severe Emphysema in an Asymptomatic Patient.

Vanishing lung syndrome (VLS) is an uncommon condition characterized by idiopathic giant bullous emphysema, resulting in the lungs appearing abnormally small on radiological scans. Some case reports have suggested a potential association between the development of this condition in young males, individuals with a history of heavy tobacco smoking, methamphetamine, and marijuana use, and those previously diagnosed with HIV. The primary diagnostic tools for vanishing lung syndrome include initial x-rays and high-resolution CT scans, which play a crucial role in confirming the diagnosis. The management of vanishing lung syndrome varies based on several factors, including the patient's functional status and the size and location of the bullae, with treatment options ranging from conservative approaches to surgical interventions. In this case report, we present the case of a 42-year-old male who was a heavy tobacco smoker, had a history of methamphetamine and marijuana use, and was previously diagnosed with HIV. He initially presented to the emergency department seeking poly-substance detoxification but was incidentally found to have giant bullous emphysema on chest imaging. After stabilizing the patient, he was discharged with instructions to follow up with a pulmonologist in two months.
