Figure 5 (A and B): Trochlear nerve schwannoma in a 53-year-old man with neurofibromatosis 2. Axial B-FFE (A) and post-contrast T1-weighted (B) images show well-defined nodule (arrow) arising from a trochlear nerve in the right ambient cistern. The nodule shows homogeneous enhancement on contrast imaging. Enhancing lesions are also seen in the right cerebellopontine cistern and para sellar regions, are part of vestibular and trigeminal schwannomas. No biopsy of trochlear nerve schwannoma was done. The lesion has been included in cyberknife therapy of vestibular schwannoma
