Emergently Managed Rare Case of Extraosseous Hemorrhagic Spinal Epidural Cavernous Hemangioma: A Case Report

INTRODUCTION: Commonly spinal cavernous hemangioma (CH) is found in vertebral body at thoracic level. Purely extraosseous epidural CH contributes only 4% of all CH. In addition, these patients usually present in their 3rd–6th decade of life. Here, we report emergently treated rare case of hemorrhagic extraosseous epidural thoracic CH in a 26-year-old male. CASE REPORT: A 26-year-old male presented with inability to walk without support with acute onset paraparesis and hypoesthesia below D7 with positive myelopathy signs. Magnetic resonance imaging showed posterior epidural well-defined homogenous mass from D6-8 region. PET scan ruled out other primary lesions in body. Intraoperative after D6-8 laminectomy extradural vascular mass was found which was bleeding on touch. With adequate hemostasis complete mass was excised and sent for sampling which revealed CH. The patient showed gradual clinical recovery with complete neurological recovery after 3 months with no signs of clinical and radiological recurrence on 2 years of follow-up. CONCLUSION: Extraosseous epidural CH is very rare presentation; hence, the differentials of schwannoma, lymphoma, tubercular/pyogenic epidural abscess, metastasis, and others must always be ruled out. They can present a decade earlier in a case of hemorrhagic CH with rapid progressive neurological deficit which warrants early surgical decompression like in our case and the foraminal or paravertebral extension needs foraminotomy or thoracotomy for complete excision.
