Herpetic pneumonia in immune deficient patients could be fatal if not treated. Considering the low prevalence of this disease, computed tomography (CT) scan findings of this condition are not well elucidated. This report describes the CT scan findings of a patient with immune system deficiency due to mycosis fungoides, and pneumonia caused by herpes simplex virus 1 (HSV-1). Bilateral alveolar infiltration with crazy-paving pattern was observed on CT scan of the lungs. The scattered crazy-paving pattern noted in the CT scan of the lungs could be suggestive of herpetic pneumonia in immunocompromised patients presenting with lung infections...

Helicobacter pylori , a gram negative pathogen, infects the stomach and gastrointestinal tract and causes pathological damage to these organs. H. pylori infection is more prevalent among people living in developing countries. Allergic asthma is a chronic inflammatory disease of the airways. Hyperinflation, hyperresponsiveness, and abnormal immunological and inflammatory processes in respiratory airways typically occur during an asthma attack. The results of recent studies have suggested an association between H...

Recurrent short episodes of bradycardia and hypotension are rarely reported as clinical manifestations of pulmonary thromboembolism (PTE). We report a case of acute massive PTE presenting with dyspnea, burning chest pain with physical activity, and recurrent transient bradycardia and hypotension at rest. Echocardiography showed a left ventricular ejection fraction of 45% with global hypokinesia. Computed tomography angiography showed a large pulmonary thromboembolism. Lytic therapy improved the right ventricular function, and the pulmonary artery pressure decreased to 38 mmHg...

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an effective and safe technique associated with a very low complication rate for the sampling of lymph nodes in those presenting with mediastinal and hilar adenopathy." We report a rare case describing the development of pneumomediastinum following EBUS-TBNA in a young patient with mediastinal lymphadenopathy secondary to non-Hodgkin's lymphoma. Conservative treatment led to spontaneous resolution of the pneumomediastinum. Pneumomediastinum is a rare but possible complication of EBUS-TBNA...

A 46-year-old woman with a 12-year history of lymphangiomyomatosis (LAM) was admitted for lung transplantation in January 2017. We decided to apply veno-arterial extracorporeal membrane oxygenation (ECMO) to manage arrhythmia and hypotension during lung transplantation, since it was not controllable with inotropic drugs. After transplanting the right (first) lung and at the time of left pneumonectomy, the body of the Swan-Ganz catheter was suddenly observed to be protruding from the right ventricular (RV) wall...
