case_images: A CT of the brain without contrast was performed in the ER, showing a questionable mass in the superior aspect of the cerebellum at midline, measuring approximately 2.8 cm x 4.3 cm in AP by transverse dimension with surrounding vasogenic edema and mild prominence of the temporal horns without a midline shift [Figure 1].

case_images: After the intraoperative pathology report confirmed that it was not lymphoma but, in fact, a spindle cell tumor, gross-total resection was achieved [Figure 3], and an external ventricular drain was left open at 10 cm of water above the ear.
