We report a case with associated laryngeal paralysis due to a dural arteriovenous fistula near the left jugular foramen. The patient was a 59-year-old male with left-sided recurrent nerve palsy, left-sided glossopharyngeal nerve palsy, left-sided sensorineural hearing loss, pulsating tinnitus and headaches. Although CT examination of the skull base revealed a single mass (φ15mm) near the left jugular foramen, further MRI examination revealed flow void signals at the lesion. The clinical symptoms, such as glossopharyngeal nerve palsy and sensorineural hearing loss, had fluctuated before treatment. MRI findings and symptoms differed from the characteristic progress of head and neck tumors; therefore, we suspected it to be angiectopia. We performed a cerebral angiography. Examination by angiography revealed a dural arteriovenous fistula near the left jugular foramen. We performed the embolotherapy via the artery for the arteriovenous fistula. After the therapy, the arteriovenous fistula disappeared and the clinical symptoms improved.
