Computed Tomography and Magnetic Resonance Imaging Features of a Huge Cavernous Hemangioma in the Pleural Space: A Case Report

ABSTRACT

A 44-year-old male with a huge left pleural mass was admitted due to chest discomfort. Chest computed tomography showed a large pleural mass with punctate calcification and serpentine-shaped enhancement in the left pleural space. Magnetic resonance imaging showed markedly high signal intensity with septa on fat-suppressed T2-weighted imaging (WI) and gradual peripheral delayed enhancement on dynamic-enhancing T1-WI. With hemangioma as the suspected diagnosis, the entire mass was surgically removed carefully and the final histopathological diagnosis was confirmed to be a cavernous hemangioma. Cavernous hemangioma of the pleural space is a rare benign vascular tumor. Precise radiologic diagnosis is important before the surgical operation of hemangiomas because of risk of massive hemorrhage requiring meticulous bleeding control.
