Th e dimensions of the pulmonary artery (PA) on CT scan and the ratio of the main PA to ascending aorta (AA) have been shown to correlate with the diagnosis and severity of pulmonary hypertension. 1 Th e mediastinal vessels are easily visualized with convex probe endobronchial ultrasound (EBUS) as the depth of penetration with EBUS is approximately 5 cm; also, the vessels run adjacent to the ai...

We encountered a 69-year-old woman displaying a filling defect within the left descending pulmonary artery (PA) on a chest CT scan and pulmonary angiography. A subsequent 2-[18F]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET) scan demonstrated focal uptake in the left hilum. A cytologic examination of transbronchial needle aspiration specimens revealed small cell carcinoma. Th...

The authors describe a case of a 31-year-old female with tuberous sclerosis, a genetic, rare, variably expressed disease. Clinical symptoms were chest pain, and progressive dyspnea. Computed tomography scan of the chest showed bilateral, diffuse, small thin-walled cysts scattered throughout the lungs characteristic for pulmonary lymphangioleiomyomatosis. Computed tomography scan of the abdomen ...

Pulmonary capillary hemangiomatosis is a rare disorder characterized by a proliferation of capillaries that invade the pulmonary interstitium and alveolar septae. Herein, we report the first Brazilian case of pulmonary capillary hemangiomatosis. A 21-year-old man presented with severe pulmonary hypertension that eventually resulted in his death. Upon admission, a computed tomography scan of the...

Chronic thromboembolic pulmonary hypertension (CTEPH), a disease associated with considerable morbidity and mortality, is the consequence of unresolved thromboembolic occlusion in pulmonary vasculature. CTEPH was considered a rare disease occurring in 0.1-0.5% of patients with pulmonary emboli who survive. Recently, a much higher incidence was reported and some risk factors such as a previous p...

AIMS AND OBJECTIVES 1. To evaluate whether CT helps in the early diagnosis of pulmonary manifestations in SLE. 2. To study the pulmonary involvement and determine the incidence and type of pulmonary involvement. MATERIALS AND METHODS Thirty eight patients fulfilling ACR classification criteria for SLE were studied. Chest X-ray, pulmonary function tests (PFT), HRCT scan thorax were done. Inves...

A 72-year-old woman with no significant medical history presented to the emergency room for severe dyspnoea. The initial clinical diagnosis was acute pulmonary embolism. Heparin infusion was initiated while awaiting a computed tomographic scan but the patient's condition deteriorated dramatically and stat echocardiogram showed tamponade. Post-evacuation echo showed a dilated right ventricle wit...
