[Craniopharyngioma in adults]

Area of Science:

• Neurology
• Ophthalmology

Background:

• Craniopharyngiomas are rare tumors originating from remnants of Rathke's pouch.
• They often occur in the suprasellar region, potentially compressing optic pathways and cranial nerves.

Observation:

• A 58-year-old woman presented with decreased visual acuity and pupillary light reflex suppression.
• Visual field testing revealed specific defects: left central scotoma with inferior temporal loss, and right superior temporal field defect.

Findings:

• CT scan indicated an intrasellar tumor with suprasellar extension, appearing isodense.
• Radiological diagnosis suggested adenoma, but post-operative findings confirmed craniopharyngioma.
• All perimetric defects resolved spontaneously prior to surgery.

Implications:

• Spontaneous variations in visual field defects are characteristic of craniopharyngioma.
• Isodensity and lack of calcification on CT scans can lead to misdiagnosis, delaying appropriate treatment.
