Jacobson's Nerve Schwannoma Presenting as a Middle Ear Mass Causing Pulsatile Tinnitus: A Case Report
Neurogenic tumors of the middle ear are rare with facial nerve schwannomas (FNS) being the most common (1). Schwannomas may also rarely arise from the tympanic branch of the glossopharyngeal nerve, eponymously named Jacobson's nerve, with fewer than 10 cases in the literature (1–7). We report a case of Jacobson's nerve schwannoma (JNS) in a 22-year-old woman that was clinically and radiographically suggestive of a glomus tumor with a discussion of diagnostic and management considerations. This case represents the youngest patient reported with JNS as the age range in the existing literature is between 34 and 64 years old (4,7).
