title: Primary intrathoracic extrapulmonary hemangiopericytoma. CT and MR findings.
abstract: We report the imaging features of a rare case of primary intrathoracic extrapulmonary hemangiopericytoma. Radiography, computed tomography, magnetic resonance imaging, and angiography, were used to evaluate this rapidly growing extrapleural tumor originating from the chest wall. The studies demonstrated smooth margins, hypervascularity, and intermediate signal on T1-weighted images and increased signal on T2-weighted images.
