Pulmonary varix--pathognomonic appearance.

Pulmonary varix--pathognomonic appearance.

A well defined lung mass with clear margins and no other signs such as lymphadenopathy, pulmonary infiltration, consolidation, collapse or bone involvement usually indicates a benign lesion, whether a tumour such as an adenoma (carcinoid), cyst or vascular abnormality. Bronchogenic, pericardial and hydatid cysts do not show contrast enhancement, adenomas do enhance but not as significantly as v...

Pulmonary varix.

Pulmonary varix is a rare disorder which is usually discovered by change during the third to sixth decade in an asymptomatic patient. The 37th example is reported with a review of the literature. The disorder is possibly congenital and may affect any lobe. Pulmonary angiography is the preferred procedure for diagnosis. If symptoms are present, they can usually attributed to associated cardiopul...

Sacciform varix of right pulmonary vein.

Pulmonary varix associated with an anomalous unilateral single pulmonary vein mimicking pulmonary arterio-venous malformation.

A 52-year old female was admitted for treatment of lung cancer in the right upper lobe. A left-sided serpentine opacity was incidentally detected and a pulmonary arterio-venous malformation was suspected (Fig. 1). However, pulmonary varix associated with an anomalous unilateral single pulmonary vein was diagnosed by imaging studies (Fig. 2, Supplementary Video 1). Supplementary material (Video ...

Pulmonary sequestration: ultrasonic appearance.

Pulmonary sequestration is a congenital anomaly in which aberrant, nonfunctioning lung tissue receives its entire blood supply from the systemic circulation. Early diagnosis may be difficult because the radiographic and clinical presentation may be mimicked by other lesions, such as cystic adenomatoid malformation, congenital bronchogenic cyst, pleural effusion, congenital diaphragmatic hernia,...
