Resumo
Os autores relatam um caso de meningeoma atípico da goteira olfatória, acometendo um paciente de 74 anos, do sexo masculino, apresentando-se com quadro de hipertensão intracraniana e confusão mental. Após exérese cirúrgica, houve recidiva local precoce e metástase ganglionar cervical. As metástases extracranianas de meningeomas intracranianos já foram bem documentadas, mas são raramente encontradas. Ocorre em menos de 0,1% desses tumores. Os locais mais comuns dessas metástases são os pulmões (60%), o fígado (34%), os linfonodos cervicais (18%), os ossos longos, a pélvis e o crânio (11%).
Abstract
The authors present a case of atypical olfactory groove meningioma in a 74-year-old man. Four months after its surgical ressection the patient was readmitted presenting left hemiparesis and cervical mass. A computed tomographic scan revealed the presence of recurrent frontal tumor. A transcutaneous needle biopsy of cervical ganglion revealed atypical meningioma. Extracranial metastasis of intracranial meningiomas are well recognized, but seldom encountered. Its incidence has been estimated to be less than 0,1% for this type of tumors. The most frequent sites for metastatic seeds of meningiomas are the lungs (60%), liver (34%), cervical lymph nodes (18%), long bones, pelvis and skull (11%).
