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).

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.

MRI confirmed expected partial resection of the suprasellar mass as well as the decreased mass effect on surrounding tissues [Figure 2].
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.

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