Spinal haemangiolipoma. Three case reports

Three cases of haemangiolipoma are described. Two of them were in the thoracic region and one in the lumbar region. All of them were subtotally removed, positively diagnosed histologically and good recovery was obtained. In reviewing 16 previous cases, the clinical characteristics, neurological features and neuroradiological findings were noted. Spinal extradural haemangiolipomas show a high incidence in middle-aged people and at the mid-thoracic level. Usually they show the signs of an extradural space-occupying lesion. Sometimes, worsening and improving are found particularly in female cases. Reviewing the existing literature, our diagnosis and procedures stress the importance of technical aspects in performing myelography and the findings of CT scanning.
