Jugular foramen tumor causing isolated hypoglossal nerve palsy: a case report

Multisequence MRI confirmed compression of the hypoglossal nerve by a left jugular foramen tumor. This case is unique in that the tumor, despite its location, manifested solely as hypoglossal nerve palsy, an atypical presentation that can lead to misdiagnosis. This case report highlights the importance of high-resolution imaging and multidisciplinary collaboration in diagnosing skull base lesions and explores the anatomical relationship between the hypoglossal nerve and jugular foramen in disease pathogenesis.
