title: Solitary spinal epidural cavernous haemangiomas as a rare cause of myelopathy.
abstract: Cavernous haemangiomas rarely occur in the spinal epidural space. We report the case of a 27-year-old man who presented with myelopathy secondary to spinal cord compression from a purely epidural lesion. The imaging characteristics of cavernous haemangiomas are unique, reflecting a highly vascular lesion. Key differentiating features from intracranial or intramedullary lesions include the lack of a surrounding hemosiderin ring and popcorn appearance. An urgent referral to a neurosurgeon is recommended given the possibility of acute neurological deterioration from intralesional haemorrhage, and good recovery from early surgical resection. Preoperative planning with thorough patient counselling and availability of matched blood is important, and an en bloc resection approach should be taken to minimise blood loss. In this case, the patient experienced complete recovery after surgical resection. No recurrence after complete resection has been reported in the literature. This suggests a good long-term outcome for the patient and that no early adjuvant therapy is necessary.
