Fifteen patients with simultaneous presentation of meningiomas with other intracranial tumours are reviewed.

The literature relating to meningiomas associated with other intracranial tumours is reviewed and the possible pathogenetic correlations are discussed. A diagnostic pitfall may occur for metastasis into a meningioma, glioma surrounding a meningioma and different suprasellar lesions.

Abstract
Fifteen patients with simultaneous presentation of meningiomas with other intracranial tumours are reviewed. The associated tumours included a brain metastasis in six cases, glioma in three, pituitary adenoma in two, craniopharyngioma in one,acoustic schwannoma in two and brain lymphoma in one. A correct preoperative radiological diagnosis was made in 12 patients; in three others the associated tumour was discovered at operation and by histological studies. A one-stage removal of both tumours through the same approach was performed in nine patients, whereas six others underwent two-stage operations with an interval of 1 - 13 months. The literature relating to meningiomas associated with other intracranial tumours is reviewed and the possible pathogenetic correlations are discussed. A diagnostic pitfall may occur for metastasis into a meningioma, glioma surrounding a meningioma and different suprasellar lesions. The surgical indication and management of meningiomas may be significantly influenced by the presence of another different intracranial tumour.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
