Which of the following findings is associated with Neurofibromatosis type 2?

Neurofibromatosis type 2 (NF2) is primarily characterized by the development of bilateral vestibular schwannomas (previously known as acoustic neuromas), which are tumors that arise from Schwann cells of the vestibulocochlear nerve (cranial nerve VIII). These schwannomas can lead to hearing loss, tinnitus, and balance issues because of their location and the functions of the auditory nerve. This association makes it a hallmark finding of NF2.

While optic nerve tumors and meningiomas can be associated with other neurofibromatosis types (particularly in Neurofibromatosis type 1), they are not the defining feature of NF2. Café-au-lait spots are also primarily associated with Neurofibromatosis type 1. The presence of bilateral vestibular schwannomas is pivotal for diagnosing NF2 and distinguishing it from other conditions, as it directly impacts the clinical management and prognosis of patients with this disorder.
