[Etiology, Genetic Features and Clinical Presentations in Craniopharyngiomas].

Craniopharyngiomas are among the most challenging intracranial tumors for neurosurgeons. Their management is complicated due to growth patterns such as infiltration into the pituitary stalk, chiasma, and hypothalamus. Therefore, patients may present with various conditions such as endocrine disorders, visual disturbances, or hypothalamic dysfunction in the first medical examination. Moreover, surgical management is challenging because of the high risk of recurrence. Two well-known histological subtypes include adamantinomatous and papillary craniopharyngiomas, and recent advances in genetic analysis have provided significant findings about these subtypes. The adamantinomatous subtype can be distinguished by mutations in CTNNB1, whereas the V600E mutation of the BRAF gene characterizes the papillary subtype. This review describes the etiology, genetic features, and clinical presentations of craniopharyngiomas.
