CT and MRI Manifestations of Hemangiopericytoma in Central Nervous System / 实用放射学杂志

ABSTRACT

Objective To investigate the CT and MRI features of the hemangiopericytoma (HPC) in central nervous system(CNS) and improve its diagnostic accuracy. Methods The CT and MRI features of the HPC in CNS proved by operation and pathology were retrospectively analyzed and the criteria of diagnosis and differential diagnosis were summarized.Results 7 of 9 cases were intracranial and 2 were intraspinal. The lesions appeared homogeneous high density in 4 cases on plain CT scans and 3 cases appeared inhomogeneous density, 4 cases appeared isointense with cortical gray matter on both T_1-weighted and T_2-weighted images, 3 cases were heterogeneous. All contrast-enhanced scans showed marked enhancement.Conclusion The accuracy diagnosis of HPC in CNS can be made by CT and MRI.
