Craniopharyngiomas in two consanguineous siblings: case report

OBJECTIVE AND IMPORTANCE: We describe a double case of craniopharyngioma in consanguineous siblings, suggesting the disease is sometimes genetic. CLINICAL PRESENTATION: Two typical adamantine craniopharyngiomas were observed in two consanguineous siblings. The brother and the sister, whose parents were first cousins, developed the tumors at the same age. INTERVENTION: The male patient was operated on using a frontopterional approach, and the tumor was completely resected. The patient remained free from recurrence 9 years after surgery. His older sister died after tumor removal was attempted at another institution. CONCLUSION: To our knowledge, such a connection has never been reported in the literature. It suggests that craniopharyngioma, which is usually sporadic, can also be transmitted in an autosomal recessive manner.
