Abstract
PURPOSE: To retrospectively review the clinicopathological features and computed tomography (CT) and magnetic resonance imaging (MRI) findings of spinal solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) tumors.
MATERIALS AND METHODS: Eleven patients with surgically and pathologically confirmed spinal SFT/HPC were enrolled. Their clinicopathological data and imaging findings were retrospectively reviewed.
RESULTS: There were eight male and three female patients with a median age of 42 years (range, 26-65 years). Of the eleven patients, five patients were classified as grade Ⅰ, four were grade Ⅱ and the remaining two were grade Ⅲ. CT or MRI imaging showed a well-defined (n = 8) or ill-defined (n = 3), oval (n = 4), irregular (n = 3), dumbbell-shaped (n = 3) and striped (n = 1) mass with heterogeneous (n = 10) or homogeneous (n = 1) density. The lesions appeared isointense (n = 4) or hypointense (n = 5) on T1WI weighted MRI and mildly hyperintense (n = 3) or hyperintense (n = 6) on T2 weighted MRI images. Bone destruction was observed in seven cases, including osteolytic (n = 6) and osteoblastic (n = 1) patterns. Calcification was observed in only one case. On enhanced CT/MRI images, marked (n = 9), mild (n = 1) heterogeneous and marked homogeneous (n = 1) enhancement could be observed in this study.
CONCLUSION: Spinal SFT/HPC commonly appears as a well-defined solitary mass characterized by a black and white appearance that is marked with heterogeneous enhancement with or without bone destruction.
