RESUMO
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.

A 30-year-old immunocompetent female presented with right flank pain since 3 years. MRI revealed a large well-defined T1 and T2 hypointense mildly enhancing lesion in the right anterior pararenal space displacing the right kidney and encasing the right ureter with T2 hyperintense wall thickening of the left renal pelvis and ureter. A provisional diagnosis of solitary fibrous tumour was kept. Bilateral double J stenting was done for hydronephrosis. Surgical debulking of the lesion was done with biopsy from the left periureteral wall thickening and was found to be myelolipoma on histopathological examination. This case is a novel variety of myelolipoma which is lipid poor, extra-adrenal and in bilateral perirenal and periureteric location.
