STUDY DESIGN: A case of juxtaposition of a purely extradural cavernous hemangioma and an intradural schwannoma in the thoracic spine is reported. OBJECTIVES: The objectives of this study were to present a rare and before-surgery unexpected combination of spinal tumors, which may complicate surgical removal; and to discuss the radiologic features and the possible pathogenesis of this combination of tumors and its implications on surgical therapy. SUMMARY OF BACKGROUND DATA: Juxtaposition of different spinal tumors is exceedingly rare in patients without neurofibromatosis. To the authors' knowledge, no combination of a purely epidural spinal cavernous hemangioma with an intradural schwannoma has been previously reported. MATERIAL AND METHODS: A 47-year-old woman presented with progressive paraparesis. Magnetic resonance imaging revealed a partly cystic intradural mass at the T6-T7 level and a solid extradural intraforaminal component that demonstrated slightly different signal characteristics. An intra-/extradural schwannoma was assumed. RESULTS: Surgical exposure displayed a highly vascularized lobulated mass within the left neuroforamen at T6-T7. There was no continuity with the larger intradural, cystic, and mildly vascularized lesion. Histologic examination diagnosed an extradural cavernous hemangioma and an intradural schwannoma. CONCLUSIONS: The segmental juxtaposition of lesions should be considered in the differential diagnosis of spinal pathology.
