ABSTRACT
A 17-year-old boy presented with somnolence and mental confusion. Physical examination demonstrated motor disturbances. Laboratorial investigation showed elevated levels of alpha-fetoprotein in serum and cerebrospinal fluid. The CT scan revealed a heterogeneous mass at the pineal region. At the MRI, this lesion was hypointense on T1 and hyperintense on T2-weighted images, enhancing after contrast administration. The patient underwent a surgical biopsy, which defined the diagnosis of yolk sac tumor. We emphasize the correlation of neuroimaging and pathological findings of this rare pineal region tumor.
RESUMO
Um menino de 17 anos de idade apresentou-se com sonolência e confusão mental. O exame físico demonstrou distúrbios motores. A investigação laboratorial revelou aumento dos níveis de alfafetoproteína no soro e no líquor. A TC de crânio revelou massa heterogênea na região pineal. A RM, a lesão era hipointensa em T1 e hiperintensa em T2, com realce após a administração de contraste. O paciente foi submetido a biópsia cirúrgica, a qual definiu o diagnóstico de tumor do seio endodérmico. Enfatizamos a correlação entre os achados patológicos e de neuroimagem deste raro tumor da região pineal.
