Abstract:
Objective To study the MRI findings in a series of intracranial hemangiopericytomas, and to compare these findings with those of intracranial meningiomas. Methods The MRI appearances and clinical features in 27 cases of intracranial hemangiopericytomas and 236 cases of intracranial meningiomas were retrospectively reviewed. All cases were proved by operation and pathology. The data were evaluated by using ? 2 test, rank sum test, and Logistic Regression. Results Sex (? 2=6 981), shape of tumor (? 2=39 949), signal voids of vessel in tumor (? 2=12 366), necrosis or cystic degeneration in tumor (? 2=37 432), the type of dural attachment ( broad based or narrow based ) (? 2=16 956), T 1WI signal intensity (? 2=14 880), T 2WI signal intensity (? 2=37 068), enhanced degree of tumor (? 2=10 081), homogeneous degree of tumor after contrast enhancement (? 2=17 014), and duration time were significant different ( P
