Abstract:
Objective To evaluate the MRI findings of synovial hemangioma.Methods Twenty-three patients with synovial hemangioma were analyzed retrospectively,and MRI characteristics were summarized.Results Of the 23 patients,there were localized type in 6 and diffuse type in 17.Localized tumors located in the articular synovial tissue and didn't invade articular capsule and peripheral tissues.T hey had envelope,well-defined margin and regular shape.5 cases showed heterogeneous signal with iso-intense or hypo-intense on T1WI,hyper-intense and internal patchy or multiple pinstripe hypo-intense on T2WI and fat-suppression sequence.Diffuse tumors distributed inside and outside the articulation,and invaded the articular capsule or peripheral tissues.17 cases were heterogeneous signal with iso-intense or hypo-intense and internal patchy or sinuous hyper-intense on T1WI,hyper-intense and internal patchy,nodular and multiple pinstripe hypo-intense on T2WI and fat-suppression sequence.Thick flow void of the vessels were showed in 6 cases and phlebolithes were showed in 3 cases.15 cases underwent contrast-enhanced scan,and the tumors showed patchy,nodular or tortuous vascular heterogeneous enhancement with internal patchy,nodular or cord-like non-enhanced areas.Conclusion Fatty-fibrous tissues and flow void of the vessels in the tumor are valuable MRI features for diagnosis of the synovial hemangioma.
