Balo's Concentric Sclerosis Mimicking Cerebral Tuberculoma.

Balo's concentric sclerosis (BCS) is considered a rare variant of multiple sclerosis, which often mimics an intracranial neoplasm or abscess. We report the case of a 21-year-old woman presenting with BCS while undergoing treatment for pulmonary tuberculosis. Initial brain magnetic resonance imaging (MRI) findings were similar to those for cerebral tuberculoma, multiple metastases, or abscesses.

Pattern-specific changes and discordant prognostic values of individual leg-muscle motor evoked potentials during spinal surgery.

Objective: The aim of the study is to evaluate the efficacy of muscle motor evoked potentials (mMEPs) in individual leg muscles for spinal surgery monitoring.

Methods: Data were obtained from 209 patients who underwent spine surgery with intra-operative mMEP monitoring in the tibialis anterior (TA) and abductor hallucis (AH) muscles. The mMEP generation, pattern-specific mMEP loss and recovery, and the accuracy of individual mMEP changes in predicting postoperative motor deficit were assessed.

Reflex movements in patients with brain death: a prospective study in a tertiary medical center.

Reflex movements have been reported to occur in up to 75% of brain-dead patients, but this issue has not been addressed in Korea. The patients admitted to our hospital who met the criteria for brain death were enrolled between March 2003 and February 2005. The frequency and type of reflex movements in these patients were evaluated prospectively using a standardized protocol.
