A Rare Convergence: A Case Report on Bilateral Hypoglossal Schwannoma in a Patient with Charcot-Marie-Tooth Disease 2

Abstract

This case presents a rare co-occurrence of Charcot-Marie-Tooth disease type 2 (CMT2) and schwannoma, shedding light on
the intricate relationship between two neurogenic disorders. CMT is a hereditary sensorimotor peripheral neuropathy while
schwannoma is a benign encapsulated tumor involving Schwann cells. The co-occurrence has been previously described in
2 patients in a family with CMT type 1A. Our case reports the first documented instance of the co-occurrence of bilateral
hypoglossal schwannoma in CMT2.
