Abstract:
Introduction: Synovial hemangioma is a benign soft-tissue tumor of vascular origin.
Hemangioma only accounts for 1% of all bone lesions and is mostly an incidental finding among
the primary skeleton tumors. A delay in diagnosis results in joint degeneration and osteoarthritic
damage because of infiltrating tumor growth.
Case Presentation: We presented a rare case of an intra-articular synovial hemangioma in a 13-
year-old pediatric patient who was asymptomatic for 5 years. She attended orthopedics OPD at AIIMS,
Mangalagiri. Surgical excision of the mass and partial synovectomy was done. Synovial hemangioma
came out to be the diagnosis following a histologic study.
Conclusion: As radiography has limited diagnostic ability, synovial hemangiomas are difficult
and challenging to identify on an outpatient basis. Histological examination and magnetic resonance
imaging are extremely helpful. To minimize the hemarthrosis risks, early complete excision
can be used as the best treatment modality.
