Pineal yolk sac tumor: correlation between neuroimaging and pathological findings
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.
