Lumbar extradural dumbbell cavernous hemangioma: A rare lesion

Abstract

A 52-year-old female presented with slowly progressive left lower limb polyradiculopathy. MRI of the lumbar region revealed an extradural dumbbell mass at L3 vertebral level, isointense on T1W and hyperintense on T2W images with homogenous contrast enhancement and extending into paraspinal region through left L3/4 foramen. L2 to L 4 left hemilaminectomy and excision of intraspinal part of tumor was performed. Histopathological examination revealed presence of cavernous hemangioma. This case is reported because of its rarity, unusual dumbbell shape of lesion and difficulty in making a preoperative diagnosis without a coexisting bone lesion.
