RESUMOA hipófise e a região selar podem ser acometidas por uma série de tumores. Nesse PALAVRAS-CHAVENeoplasia do colo, hipófise, metástase neoplásica. ABSTRACT Metastatic colonic adenocarcinoma from sellar region: case report The pituitary gland and sellar region may be a site for a number of tumors. In this context a rare but feasible differential diagnosis is metastasis. The diagnosis of metastasis in the sellar KEY-WORDSColonic neoplasm, pituitary gland, neoplasm metastasis.

We report a case of coincident craniopharyngioma with an unruptured aneurysm at the right M1-M2 segment of the middle cerebral artery; and discuss the surgical approach to two different pathologies treated at same surgical time, as well as current theories to explain the coincidence or association between tumor and vascular lesions at the sellar and suprasellar regions. The patient was a 59-year-old woman; with a history of visual impairment and headache. Both lesions were identified by magnetic resonance imaging (MRI) and cerebral angiography, and were treated surgically. We suggest individualized treatment for each case, choosing the best neurosurgical approach to achieve an appropriate treatment of both pathologies in the same operative session. RESUMORelatamos um caso de craniofaringioma com aneurisma não roto no segmento M1-M2 da artéria cerebral media à direita; e discutimos a abordagem cirúrgica a duas patologias diferentes, porém tratadas no mesmo tempo cirúrgico, assim também como as teorias atuais para explicar a coincidência ou associação entre os tumores e as lesões vasculares na região selar e suprasselar. Paciente mulher de 59 anos, com história de deficiência visual e cefaleia. Ambas as lesões foram identificadas, por ressonância magnética (RM) e angiografia cerebral, e tratadas cirurgicamente. Sugerimos tratamento individualizado para cada caso, escolhendo a melhor abordagem neurocirúrgica para o tratamento adequado de ambas patologias no mesmo ato cirúrgico.
