Male, 13 years old, with history of cerebellar juvenile pilocytic astrocytoma, yearly follow-up examination. Postoperative findings are again seen compatible with tumor resection from the posterior fossa. A small resection cavity in the left paramedian cerebellum is unchanged. Minimal surrounding T2 hyperintensity and susceptibility are unchanged. No edema, mass effect or pathologic enhancement is observed. The brain parenchyma otherwise demonstrates normal signal intensity and morphology. Ventricular size is stable and within normal limits.
Redemonstration of postoperative findings with no evidence of recurrent tumor.
