Atypical spinal epidural capillary hemangioma : case report

Background: Hemangiomas are benign vascular malformations that can involve the spine. Pure epidural hemangiomas are rare and represent only 4% of all epidural lesions. Most hemangiomas are of the cavernous type; the capillary variant is atypical, and only ten cases have been reported in the literature. Case Description: A 69‑year‑old female presented with nonspecific dorsal pain. Magnetic resonance imaging (MRI) showed a spinal epidural tumor at the T9‑T10 level. Following a T9‑T11 laminectomy, the lesion was completely resected en bloc. Histopathologic analysis showed a pure epidural capillary hemangioma with adipose tissue mesenchyma. Conclusions: Although epidural capillary hemangiomas are extremely rare, they should be considered among the differential diagnoses of extradural, extramedullary spinal lesions. Further, they must be differentiated from other more common lesions such as meningiomas and schwannomas. The recommended surgical management is en bloc gross total excision
