case_images: Magnetic resonance imaging (MRI) showed a pineal irregular mass occupying the superior cerebellar and quadrigeminal cisterns with hyposignal on T1, medium signal on T2 and heterogeneous enhancement after gadolinium injection [Figure 1].
case_images: Histopathologic view. Cells of several shapes may be seen arranged in a lobular manner. They exhibit an eosinophilic cytoplasm with intervening epithelial and intracellular mucin containing cells. Thin-walled vessels surrounded by a fibrous framework may be appreciated
