The auditory brainstem response (ABR) may be a predictor of postoperative cochlear nerve function. In this study, the course of intraoperative ABR monitoring was analyzed to find predictive markers for postoperative hearing function. ⋯ Intraoperative ABR development is a predictive factor for postoperative hearing outcome. Deterioration should be avoided, because ABR improvement as a result of good status at the beginning of surgery could not be assumed.

We hypothesized that the entry site of the basivertebral vein into the basivertebral foramen of C2 might localize the subdental synchondrosis between the odontoid process and body of C2, which may be helpful for odontoid fracture classification. ⋯ The basivertebral foramen is a consistently present anatomic reference point for the subdental synchondrosis even if the latter cannot be seen on conventional radiographic imaging. Our MRI data might also be useful in helping differentiate lesions affecting C2 from normal subdental cartilaginous remnants that can be encountered on imaging.

Intracranial Cystic Myofibroblastoma: a Case Report with Literature Review.
Myofibroblastoma is a rare benign soft tissue tumor comprised of contractile myiod cells mostly in mammary gland. Only 4 prior cases arising in the central nervous system have been reported in the literature. We present a case of myofibroblastoma with a cystic component. ⋯ This is a rare condition of a benign soft tissue tumor of mammary gland presented primarily in the brain. The literature on myofibroblastomas arising in the central nervous system is reviewed.
