Craniopharyngioma of the temporal lobe.. Axial T1-weighted (A) and T2-weighted (B) MR images show a large cystic mass in the left temporal lobe, which contains small solid portions on its medial aspect (arrow). Sagittal contrast-enhanced T1-weighted (C) MR image shows thick peripheral rim enhancement, and well enhancing solid portion in the inferior part of the mass (arrow). Photomicrograph (D) shows classic adamantinomatous craniopharyngioma with peripheral palisades of epithelial cells (arrows), containing loose squamous cells separated by intercellular fluid. Delicate squamous epithelial cells contain wet keratin (open arrows) and calcification (arrowheads) (original magnification, x100; hematoxylin-eosin staining).

T1-weighted (665/14/2 [repetition time/echo time/excitation]) and T2-weighted (4200/99/2) MR images showed a large cystic mass with a small solid portion in the left temporal lobe (Figs. 1A, B). Gd-DTPA enhanced T1-weighted images showed marked enhancement of a thick peripheral wall and solid portion (Fig. 1C).
