Fig. 1. Multi-slice ECG-gated CT scan (slice thickness, 1.25 mm). (A) Contrast enhanced axial image, the right pulmonary artery was completely occluded by a mass (arrowhead). Endovascular component and extension into the surrounding pulmonary parenchyma were well shown. (B) 3D volume-rendered reconstruction (oblique view) shows the extension (arrowheads) and bronchial artery hypertrophy (arrows...

Pulmonary infarction usually appears as a hump-shaped triangular opacity with its base applied to a pleural surface. In some cases, pulmonary infarctions may appear as a pseudo tumoral opacity mimicking lung cancer. Thoracotomy could be prevented by repeating CT scan in properly selected patients.

Pulmonary embolism (PE) is a preventable cause of morbidity and mortality which needs prompt recognition. Ventilation-perfusion (V/Q) scan is a well-established diagnostic test for evaluation of suspected PE. We report a 32-year-old woman with history of rheumatologic disease and acute dyspnea, who was referred for V/Q scintigraphy. The planar images revealed multiple mismatched defects through...

conclusions in conclusion complementary to the previous studies our results have demonstrated that bronchial artery embolization remains as one of the most efficient procedures in managing massive hemoptysis, with minimal rate of complications. patients and methods all the patients had already been assessed by computerized tomography (ct) to localize and delineate the underlying etiology except...

A dramatic case of occlusion of the right pulmonary artery is presented. The diagnosis was clearly established by means of a lung scan and a radionuclide pulmonary angiogram. The entire course of the disease process was followed by radionuclide studies with a gradual but persistent return to normal. Due to the preciseness of the evidence presented, contrast angiography was not.thought necessary.

Chronic thromboembolic pulmonary hypertension is a rare but underdiagnosed disease. The development of imaging played a crucial role for the screening and the decision of operability over the past few years. Indeed, chronic thromboembolic pulmonary hypertension is the only type of pulmonary hypertension with a potential curative treatment: pulmonary endarterectomy. It is a complexe surgical pro...

The diagnosis of acute pulmonary embolism has always been challenging. However, it has recently been greatly assisted through advances in radiological imaging. While imaging techniques are widely available, they cannot always be utilized. We report a case of acute pulmonary embolism in a patient with several prior pulmonary resections that would likely result in a non-diagnostic V/Q scan and ac...
