-Meningiomas are benign tumors arisising from arachnoid cells and represent the commonest asymptomatic intracranial tumors. We analysed 69 supratentorial meningiomas managed by the Neurosurgical Tumor Group of the Clinics Hospital of Medicine School of São Paulo University (September 1995 to September 1997. Age, sex, edema degree, tumor site, surgical complications and mortality were studied. Edema degree was defined by radiological methods (CT and MRI). Forty-seven patients were women and average age was 58 years. Type II of edema degree was predominant (38.7%). Twenty-nine patients had parasagital meningiomas and 40 presented convexity tumors. Simpson I resection was obtained in 48 procedures, II in 18 and III in two surgical removals. Nine cases complicated (transitory deficits, 6; permanent deficit, 1; and infection, 2). Death occurred in two patients. Morbity and mortality had relation with age, falx tumors and attempt of radical surgical removal. Edema degree did not modify mortality and morbity rates.KEY WORDS: supratentorial meninigiomas, surgery, brain edema, venous sinus.Os meningiomas são tumores originados de células das vilosidades aracnóideas e constituem os tumores intracranianos assintomáticos mais comuns. Representam cerca de 13-18% dos tumores intracranianos primitivos 1,2 , atingindo mais frequentemente indivíduos com idade entre 20 e 60 anos e acomentendo principalmente o sexo feminino. 3
ResumoAs metástases cerebrais de carcinoma endometrial (CE) são incomuns – provavelmente em virtude do baixo tropismo de suas células pelo sistema nervoso central (SNC) – e poucos casos são descritos detalhadamente na literatura. Acredita-se que tumores mais invasivos e indiferenciados apresentem maior probabilidade de metastizarem. Embora a presença de uma lesão encefálica em uma paciente com CE seja altamente sugestiva de metástase, em razão de sua raridade, outros diagnósticos devem ser considerados. Por outro lado, a hipótese de metástase cerebral de CE deve ser considerada em casos em que não se identifica o foco primário. É possível que a expressão de receptores de progesterona, o gene HER-2/Neu e mutações no gene p53 estejam relacionadas à ocorrência de metástases centrais. A propósito de um caso, os autores discutem aspectos diagnósticos e terapêuticos e tentam contribuir para um melhor entendimento da fisiopatologia da doenca.
