MRI demonstrated 3 cmx2.5x3.3 cm homogenously contrast enhancing mass in the cerebellar-pontine angle with extension medial to the seventh/eighth nerve complex and slight extension into the internal auditory canal (Fig. 3a). MR venography demonstrated patent transverse/sigmoid sinuses bilaterally. Postoperatively the patient was discharged home postoperative day 3 neurologically intact with post-resection imaging that demonstrated complete resection (Fig. 3b).
