NF2 and Vestibular schwannoma: While NF2-associated vestibular schwannomas typically exhibit similar morphologic features as sporadic tumors with a predominance of cellular Antoni A regions which may exhibit palisading nuclei and Verocay bodies (Fig. 2e) and typically a lower proportion hypocellular Antoni B regions (Fig. 2f), they may have an increased mitotic index and higher risk of recurrence compared to sporadic lesions, possibly due to the polyclonal origin of some masses, difficulty with complete resection, and the presence of additional small nodules along the nerves.
