Abstract	Os tumores do osso temporal sao raros e geralmente apresentam sintomas como otorreia, otalgia e hipoacusia, por isso podem ser facilmente confundidos com um processo infeccioso, retardando o diagnostico e piorando o prognostico do paciente. KS, 7 anos, masculino. Estado geral: regular. Ao exame: consciente; linfonodos cervicais palpaveis, moveis; massa palpavel, imovel e indolor em topografia retroauricular esquerda; surdez a esquerda e paralisia facial esquerda. Tomografia computadorizada de crânio evidenciou lesao expansiva do osso temporal captante de contraste com extensao para fossa media e posterior do crânio. Realizada complementacao radiologica com ressonância de encefalo, a qual apresentou imagem hipercaptante em T1 contrastado. Nas incidencias T2, observa-se edema lobotemporal adjacente a lesao. Exame angiografico cerebral apresentou obstrucao tumoral do seio sigmoide esquerdo. Paciente submetido a mastoidectomia radical esquerda com ligadura e resseccaodo seio sigmoide esquerdo resultando em resseccao completa lesional. Anatomopatologico e exame imunoistoquimico compativeis com adenocarcinoma. Encaminhado para terapia oncologica com quimioterapia e radioterapia. Obito apos quatro meses do tratamento neurocirurgico. O diagnostico precoce associado com a extensao do tumor acarreta melhor ou pior prognostico para os pacientes acometidos por essa molestia. Tumors of the temporal bone are rare and usually have symptoms such as otorrhea, otalgia and hearing loss and, therefore, can be easily confused with an infectious process delaying diagnosis and worse prognosis. KS, age 7, male. General condition: regular. On examination: conscious, palpable cervical lymph nodes, mobile; palpable mass, painless and property surveying retroauricular left, left deafness and facial paralysis left. Cranial computed tomography showed a lesion of the temporal bone with extensionto the middle fossa and posterior skull that enhance with contrast. Performed complementation with radiological MRI brain image which showed uptake, in contrast T1. Incidences in T2, there is edema temporal lobe adjacent to the lesion. Cerebral angiography showed a tumor obstructing the left sigmoidsinus. Patient underwent left radical mastoidectomy with ligation and resection of the left sigmoid sinus resulting in complete lesional resection. Histopathological and immunohistochemical examination compatible with adenocarcinoma. Referred for cancer therapy with chemotherapy and radiation. Death within four months after neurosurgical treatment. Early diagnosis associated with tumor extension carries a better or worse prognosis for patients affected by this disease.
