Integrated Molecular-Morphologic Meningioma Classification: A Multicenter Retrospective Analysis, Retrospectively and Prospectively Validated.

Purpose: Meningiomas are the most frequent primary intracranial tumors. Patient outcome varies widely from benign to highly aggressive, ultimately fatal courses. Reliable identification of risk of progression for individual patients is of pivotal importance.

Consent for post-operative visual loss in prone spinal surgery: aligning clinical practice with legal standards.

In March 2015, the Supreme Court's landmark ruling on the common law case of Montgomery vs Lanarkshire Health Board established the doctrine of informed patient consent, setting the legal standards that doctors should abide by. In this review, our primary aim has been to establish whether, despite the well-publicised implications of the ruling in the legal community, the medical profession has altered its practice. To do this, we reviewed the consenting methods applied by surgeons within our field of neurosurgery.

5-ALA fluorescence in intraparenchymal endodermal cysts.

In recent years, new indications have been suggested for 5-ALA, particularly for cystic lesions. We report the use of 5-ALA fluorescence in an intraparenchymal supratentorial endodermal cyst of a 52-year-old female presenting with headache, progressive right side hemiparesis and anomic aphasia. She underwent an image-guided 5-ALA-assisted left minicraniotomy for fenestration of the cystic lesion into the ventricular system.
