title: [Diagnostic imaging of hemangiopericytomas].
abstract: Eight patients with histologically verified hemangiopericytomas were examined by conventional radiographic techniques (plain films, angiography including cavography) as well as by duplex sonography, CT and MRI. These imaging techniques detected solid tumors with cystic compartments. A typical computed tomographic finding was intensive contrast enhancement within the tumor. Duplex sonography revealed blood flow in the periphery of the tumor. In contrast to reports by other authors no tumor calcification was found by plain film radiography.
