Chronic subdural hematoma (CSDH) is a commonly encountered neurosurgical pathology that frequently requires operative intervention. With an increasing ageing demographic, more elderly and comorbid patients will present with symptomatic CSDH. This study evaluated clinical and radiologic factors to create a scoring system to aid prognostication. ⋯ A scoring system has been devised to predict outcome, which can aid in the necessity of surgery in certain patient demographics.

Lumbar sympathetic neurolysis (LSN) is a treatment option for complex regional pain syndrome (CRPS). We examined whether LSN-related temperature changes are associated with clinical outcome and investigated relationships between the outcome of LSN and clinical variables in patients with CRPS-I. ⋯ LSN may be effective in some patients with CRPS, irrespective of temperature changes and temperature asymmetry pattern. A short duration of pain and concurrent cold intolerance significantly predict successful LSN.

The minimum and essential thalamic areas for reducing tremor were investigated in cases treated by superselective thalamotomy in the most lateral part of the ventralis intermedius nucleus (mlp-VIM). ⋯ The important area for reducing tremor was small and narrow and was located in the mlp-VIM, where the proprioceptive ascending signals from the tremor-dominant body part are conducted. Superselective thalamotomy in the mlp-VIM was safe and effective for the long-term in patients with ET and PD.

Telemetric intracranial pressure (ICP) monitoring seems to be a promising therapy-supporting option in shunt-treated patients. Benefits become obvious when headaches are unspecific and clinical symptoms cannot be related to possible overdrainage or underdrainage. In this study, we evaluated a new telemetric device to individually adjust shunt valves according to ICP measurements. ⋯ The Sensor Reservoir is an important and valuable tool for shunt-treated patients suffering from drainage-related problems. The possibility to simultaneously recognize and solve shunt problems represents the decisive advantage. Nevertheless, measurements with the Sensor Reservoir did not allow for the determination of default valve settings or universal target ICP values.

Agenesis of the Anterior Falx Cerebri in a Patient with Planned Interhemispheric Approach to a Third Ventricle Mass.
Complete or partial agenesis of the falx cerebri may occur in pediatric patients with developmental anomalies. However, isolated agenesis of the falx in a developmentally normal adult is exceptionally rare. We describe the first reported case of a patient with a third ventricular mass associated with partial agenesis of the anterior falx cerebri, a circumstance that influenced surgical access to a third ventricular epidermoid cyst. ⋯ Partial agenesis of the falx cerebri is exceedingly rare in a developmentally normal adult, particularly in the presence of an anatomically normal superior sagittal sinus. If present, however, it is important to note this association preoperatively because partial agenesis of the falx cerebri precludes an interhemispheric transcallosal approach to the lateral and third ventricles.
