case_images: Preoperative magnetic resonance imaging (MRI) of the brain postcontrast T1-weighted MRI (a) axial view, (b) coronal view, (c) sagittal view reveals multilobulated complex mass with both cystic and solid components again seen in the suprasellar region measuring 28.7 mm x 34.5 mm x 37.2 mm (AP by TR by CC).

case_images: Postoperative magnetic resonance imaging (MRI) of the brain postcontrast T1-weighted MRI (a) axial view, (b) coronal view, (c) sagittal view reveals partial resection of the previously seen suprasellar mass with decrease mass effect and trace postsurgical hemorrhage.

case_images: MRI confirmed expected partial resection of the suprasellar mass as well as the decreased mass effect on surrounding tissues [Figure 2].
case_images: A squash preparation (a) H and E x40) shows spindled cells with fibrillary astrocytic processes and Rosenthal fibers (arrow).Tumor shows focal cellular atypia with occasional "lipidized" cytoplasm (b) H and E; x60; arrow), readily identifiable Rosenthal fibers (b and c), and numerous eosinophilic granular bodies (c) H and E; x60; arrow). Perivascular cuffing, chronic lymphocytic infiltrate is present (d) H and E; x40). Trichrome stain (e) x20 highlights the blue-staining connective tissue into which the tumor cells are invading, immunohistochemistry for glial fibrillary acidic protein (f) x20) highlights the astrocytic processes of the tumor cells.

case_images: Eosinophilic granular bodies, lymphocytic infiltrates, and Rosenthal fibers were also noted to be present [Figure 3].
