ObjectiveTo retrospectively review the clinicopathologic features and computed tomography (CT) and magnetic resonance imaging (MRI) findings of spinal solitary fibrous tumor (SFT)/hemangiopericytoma (HPC) tumors.MethodsEleven patients with surgically and pathologically confirmed spinal SFT/HPC were enrolled. Their clinicopathologic data and imaging findings were retrospectively reviewed.ResultsThere were 8 male and 3 female patients with a median age of 42 years (range, 26-65 years). Of the 11 patients, 5 were classified as grade I, 4 were grade II, and the remaining 2 were grade III. CT or MRI 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 T1-weighted MRI and mildly hyperintense (n = 3) or hyperintense (n = 6) on T2-weighted MRI. Bone destruction was observed in 7 cases, including osteolytic (n = 6) and osteoblastic (n = 1) patterns. Calcification was observed in only 1 case. On enhanced CT/MRI, marked (n = 9), mild (n = 1) heterogeneous, and marked homogeneous (n = 1) enhancement were observed in this study.ConclusionsSpinal 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.
