Our main objective was to study the reliability of the Codman MicroSensor (CMS), used for intracranial pressure (ICP) measurements, as it is used in a clinical setting. In particular, the drift from zero was studied. ⋯ In our hands, the CMS device is reliable and easy to use. The ICP recordings are stable over time, and there is only a minor zero drift. The device is today our standard method for ICP measurements.

To evaluate the efficacy and toxicity of radiosurgery in the treatment of cranial base chordoma and chondrosarcoma. ⋯ Cranial base chordomas and chondrosarcomas remain a formidable management challenge. Radiosurgery as an adjunct to surgical resection provides in-field tumor control for some patients, but radiation-related complications are relatively high, especially when radiosurgery is combined with fractionated radiation therapy.

The frontobasal interhemispheric approach for suprasellar tumors currently incorporates technological advancements and refinements in patient selection, operative technique, and postoperative care. This technique is a valid choice for the removal of suprasellar lesions with extension into the third ventricle without major sequelae related to the surgical approach. The method described here reflects the combination of the frontal interhemispheric and trans-lamina terminalis approaches.

We explored relevant regional microanatomy as it relates to the challenging anterior interforniceal (AIF) approach for removing hypothalamic hamartomas. ⋯ The technically safe AIF approach permitted limited interforniceal splitting, no major deep vein manipulation, and adequate visualization of the hypothalamus, infundibular recess, and mamillary bodies.

Intracranial cysts containing an ectopic choroid plexus or choroid plexus-like tissue have seldom been described in the literature. However, there has been no report of a spinal intramedullary cyst containing an ectopic choroid plexus. This is the first case report in the available literature of an ectopic choroid plexus tissue in the spinal cord. ⋯ Although there have been rare case reports of drop metastasis of choroid plexus papillomas in the spine, this is the first case report in the available literature of normal but ectopic choroid plexus tissue in the spinal cord.
