Hypoglossal Nerve Palsy Misdiagnosed as Tongue Tumor: A Rare Case of Calcified Hypoglossal Schwannoma

The authors hereby present a case of a calcified schwannoma of the hypoglossal nerve, which led to hypoglossal nerve palsy initially misinterpreted as a tongue tumor. This paper reviews the presentation of schwannoma of the hypoglossal nerve and offers a novel perspective on this rare condition. Diagnostic pitfalls and the diagnostic-therapeutic value are also discussed.
