case_images: Six-month surveillance imaging demonstrated rapid tumor growth with extension into the cerebellopontine angle, measuring 1.7 cm in diameter [Figure 1].
case_images: T1-weighted magnetic resonance imaging with contrast following right retro sigmoid craniectomy for tumor resection. Of note a small nodular area of enhancement is seen near the right vestibule (arrow).

case_images: MRI showed a small 2 mm nodular enhancement within the vestibule concerning for residual tumor [Figure 2].
case_images: T1-weighted magnetic resonance imaging with contrast obtained 6 months following translabyrinthine approach for resection of residual tumor. Expected postsurgical changes are seen without clear evidence of recurrent enhancing tumors.
