Abstract
Computed tomography and magnetic resonance imaging of a malignant hemangiopericytoma
in a 58-year-old woman are described. The tumor was initially found in the abdomen
and resected 34 years ago, but recurred 18 years later, followed by repeated recurrence
and eventually metastasis to the lung and then to the liver. The lung nodules were
round or oval, homogeneous, and well circumscribed while the massive tumor in the
right lobe of the liver was poorly delineated with irregular areas of cystic necrosis.
With proper setting of the repetition time and echo delay, the metastatic tumor became
distinct from the uninvolved hepatic tissue on magnetic resonance imaging. In this
case computed tomography and magnetic resonance imaging were complementary in evaluation
of such a tumor.
