Multiple meningiomas evaluated by computed tomography

The authors report ten cases of multiple meningiomas in a series of 227 intracranial meningiomas from 1977 to 1984. The incidence of multiple meningiomas was 4.4% (according to Cushing and Eisenhardt's [1938] concept of 'multiplicity' of such tumours). These results are comparable to those obtained by other authors. All patients were females and all underwent CT scan before operation. Clinical symptoms are presented along with location and size of the tumours. Pathogenetic theories and research prospects are discussed.
