Papillary Tumor of the Pineal Region: MR Signal Intensity Correlated to Histopathology

Figure 1

Sagittal FLAIR (a) shows solid and cystic portions, both containing high protein content. Axial T1 SE/MTC (b) shows more pronounced hyperintensity than the comparative T1 SE (c). T1 SE after gadolinium administration (d) confirms heterogeneous enhancement in the solid portion of the tumor and the cystic walls.
