Cavernous angiomas of the skull.

The authors present a series of 25 cases of haemangioma of the skull and review the literature. Frontal localization was the most frequent, contrary to the data in the literature which suggest predominance in the parietal region. The reported predominance of females has not been confirmed. In the present series the relation of males to females was 17:8. The radiological findings and treatment of haemangiomas are discussed. Direct puncture and injection of contrast medium is the best method of visualization of the tumour. Treatment should be surgical, consisting of total extirpation of the tumour with a margin of healthy tissue. Simple extirpation is indicated only when the soft tissues are involved and there is no bone lesion. Excision en bloc is the tehcnique of choice.
