A 28-Year-Old Man With Diffuse Bilateral Pulmonary Nodules.

CASE PRESENTATION: A 28-year-old man with a history of congenital HIV sought treatment at the ED with a chief symptom of generalized malaise and confusion of 3 days' duration. He had mild dyspnea, but no respiratory distress, and he reported no fever, chest pain, or headache. We were unable to obtain past medical, family, or social history because of encephalopathy and we had no available contact person. Review of the patient's medical record revealed he made an initial clinic visit to the Department of Pediatric Infectious Disease 5 years previously. At the time of that visit, CD4 count was 250 cells/mm3 and no known complications of HIV were documented. He was prescribed Stribild (elvitegravir-cobicistat-emtricitabine-tenofovir disoproxil fumarate) and darunavir; however, pharmacy records revealed he did not fill the prescriptions. He underwent no further clinic follow-up examinations. He grew up in California and moved to upstate New York 5 years previously.

Cannabinoid Oil Vaping-Associated Lung Injury and its Radiographic Appearance.

BACKGROUND: Lung injury associated with cannabinoid oil vaping is rapidly becoming a serious public health concern. We describe the clinical and radiographic presentations of 5 patients with lung injury associated with vaping cannabinoid oils seen at a single institution. RESULTS: Of the 5 patients with suspected vaping-associated lung injury seen at our institution, 4 required supplemental oxygen, and all these 4 were admitted to the hospital. Three patients required admission to the intensive care unit. None of the patients required mechanical ventilation. All patients demonstrated a consistent radiologic appearance of diffuse bilateral ground-glass lung opacities that spared the extreme periphery. Three patients underwent bronchoalveolar lavage, which revealed lipid-laden macrophages in 2 of them. All patients were successfully discharged from the hospital. Four received only supportive care, while the fifth required intravenous followed by oral corticosteroids. CONCLUSIONS: We report the clinical and radiographic presentation of 5 patients at our institution with cannabinoid oil vaping-associated lung injury. All patients displayed a consistent chest radiographic pattern of injury. Most responded to supportive care, although one required the addition of corticosteroids. Bronchoalveolar lavage results suggest that this injury may related to a toxic form of lipoid pneumonia.
