Bilateral epidural extension of thoracic capillary vertebral (intraosseous) hemangioma mimicking spinal meningioma.

We describe a rare case of vertebra (intraosseous) hemangioma with bilateral and symmetrical epidural extension causing cord compression in a 24-year-old woman. The epidural component was isointense to cord on both T1 and T2 sequences, and enhanced markedly and homogenously following gadolinium administration. The gradual in onset and progressive nature with the typical enhancing pattern lead the neurosurgeon to the more common diagnosis of spinal meningioma. Epidural extension of vertebral hemangiomas causing cord compression is rarely reported. Review of literatures reveal that cases that have been reported are of unilateral extension into epidural space and of cavernous type. This is the first case report of capillary vertebral (intraossous) hemangioma with bilateral extension through both intervetebral foramen into the epidural space causing myelopathy.

Proptosis presenting as a delayed sign of frontal extradural haematoma.

We report a case of a young man who presented with proptosis as a delayed manifestation of a frontal extradural haematoma (EDH) following a minor head injury. A computed tomography (CT) of the brain done 72 hours after trauma revealed a large extradural haematoma in the right anterior cranial fossa with orbital roof fracture and subperiosteal clot extension into the orbital cavity. Right frontal craniotomy with evacuation of haematoma was done and the proptosis completely resolved after surgery. The clinical course, possible mechanism and management of the patient are discussed.
