Symptomatic vertebral haemangiomas: report of two cases.

The authors reported two cases of vertebral haemangiomas with spinal cord compression. The first case deteriorated during her pregnancy. Plain radiography of the thoracic spine gave the hint for the diagnosis and computed axial tomography showed the lesion. She was treated via surgical removal with minimal improvement of her paraparesis. The second case was diagnosed after operation because there was no abnormality over the relevant vertebra and the myelogram demonstrated an extradural mass lesion compressing the lower thoracic spinal cord. The patient improved satisfactorily after total removal of the tumour. Both surgical specimens were classical pictures of haemangiomas histologically.
