Vascular Malformations Diagnosis and Treatment

Tentorial meningiomas have been discussed in many articles devoted to meningicmas of the posterior fossa.Cushing and Eisenhardt (1938) described 15 cases, Campbell and Whitfield (1948) five cases, Russell and Bucy (1953) reviewed 46 cases from the literature and described two of their own, Castellano and Ruggiero (1953) presented 21 cases of tentorial meningioma, Markham, Fager, Horrax, and Poppen (1955) described seven cases, and Tristan and Hodes (1958) eight cases.Although these tumours are notorious for their ability to escape recognition clinically, a fact noted by many of the authors above, no detailed attempt has been made to characterize the clinical picture these meningiomas present.Despite their relative rarity, tentorial meningiomas leave a lasting impression when discovered at the time of radiography or surgery in a patient suspected of having a totally unrelated con- dition.Should these tumours present a characteristic pattern, earlier recognition might improve their prognosis.Many different classifications for the location of meningiomas have been employed (Castellano and Ruggiero, 1953).However, in this survey tentorial origin was the only criterion used for selection.Since the tentorium has a large intracranial area, tumours originating from it may vary widely in the actual location of their mass.Supratentorial, infratentorial, incisural, and posterolateral are terms that will be used to suggest the principal location of each tumour.
