Craniopharyngioma status post laser ablation and proton beam radiation. There are bilateral transfrontal catheters that terminate in the suprasellar mixed cystic and solid craniopharyngioma. Although many of the cystic components of the tumor have decreased in size, the overall size of the tumor has not significantly changed, measuring up to approximately 25 mm. There is patchy T2 hyperintensity in the adjacent brain parenchyma and optic apparatus, which appears to have increased slightly in extent. The ventricles are unchanged in size and configuration. There is no midline shift or herniation. The skull and extracranial soft tissues are unchanged.
Although many of the cystic components of the tumor have decreased in size, the overall size of the craniopharyngioma has not significantly changed, measuring up to approximately 25 mm. However, the patchy T2 hyperintensity, which may represent edema in the adjacent brain parenchyma and optic apparatus appears to have increased slightly in extent.
