Challenges in intraoperative differentiation of craniopharyngioma and Rathke cleft cyst on endoscopic visualization.

Background: Craniopharyngiomas are epithelial tumors derived from the remnants of the Rathke pouch, while Rathke cleft cysts (RCC) are benign cystic lesions originating from the Rathke pouch itself [1]. Rathke cleft cysts comprise 10-15% of the hypophyseal tumors, while craniopharyngiomas are relatively rare, comprising only 2-5% of intracranial tumors [2]. Both located in the sellar and parasellar regions and share clinical symptoms including headache, visual disturbances, and endocrine dysfunction [3].

Rathke cleft cysts are congenital, non-neoplastic sellar cysts derived from remnants of embryonic Rathke pouch. Presentation of Rathke cleft cysts can be incidental; however, in larger cysts, presentation can be with headaches, visual deterioration, and pituitary and endocrine dysfunction. Here we report a rare case of identical twin boys with Rathke cleft cysts, highlighting the likely genetically driven development of cyst in this identical twin and need for cranial imaging in identical twins with anomalies of the brain.

Background: Craniopharyngiomas are benign tumors of the anterior skull base arising from epithelial remnants of Rathke pouch. They mainly occur in the suprasellar space, can be incredibly debilitating, and remain difficult to resect as they frequently involve critical neurovascular structures. Although it is embryologically possible for craniopharyngiomas to arise extracranially along the entire migrational path of Rathke pouch, these remain exceedingly rare, especially among adults, and can be mistaken for nasopharyngeal cancer.

Adamantinomatous craniopharyngioma (ACP) is a rare sellar region tumor seen in 0.5-2 cases per million persons each year, presenting a bimodal distribution that peaks at 5-15 years in children and 45-60 years in adults. Arising from embryonic remnants of the Rathke pouch epithelium, ACPs are associated with calcifications in 90% of cases and grow cranially toward the floor of the diencephalon.

Craniopharyngiomas are challenging tumors of the central nervous system that originate from epithelial remnants of the Rathke pouch. Despite maximum safe resection, these tumors present a high tendency to recur (∼20%-40%), even after apparent gross total resection. The management of recurrent craniopharyngiomas is more challenging, associated with a higher risk of permanent morbidity and complications.
