Giant Craniopharyngioma.

Abstract

A 6-year-old girl presented with moderate-intensity headache, frequent vomiting, visual disturbance, and left-sided decreased hearing for 7 months. The neurologic examination revealed a right upper motor neuron facial nerve palsy, left-sided 4-mm sluggish pupil (right: 3-mm reactive), and unsteady gait. Fundoscopy was notable for bilateral papilledema. Brain magnetic resonance imaging with contrast demonstrated a giant multiloculated suprasellar cystic lesion (9.7 × 10.5 × 7.6 cm). It extended to the left anterior cranial fossa, both middle cranial fossae, and posterior fossa prepontine region with consequent effect on the brainstem and moderate hydrocephalus. The patient underwent a right frontal external ventricular drain insertion and left frontotemporal craniotomy and tumor resection. Histopathologic sections were compatible with adamantinomatous craniopharyngioma. Giant craniopharyngiomas have rarely been reported. This article presents the clinical and radiologic outcomes of a patient with a giant craniopharyngioma.
