The authors present the results of stereotactic radiosurgery performed in a consecutive series of children with arteriovenous malformations (AVMs) and analyze factors associated with successful radiosurgery for this condition. ⋯ Radiosurgery was successful in the treatment of the majority of pediatric patients suffering from AVMs, and morbidity levels were minimal. The radiosurgery-based AVM grading scale accurately predicted these outcomes. Children whose AVMs are obliterated after radiosurgery should undergo repeated angiography after they reach adulthood to rule out the possibility of a recurrent nidus that would expose them to an ongoing risk of hemorrhage.

Controlled Clinical TrialProspective controlled trial of gamma knife surgery for essential trigeminal neuralgia.
Stereotactic radiosurgery is an alternative to conventional surgery for the treatment of trigeminal neuralgia. The authors conducted a prospective evaluation of the safety and efficacy of this method in a large series of patients. ⋯ Radiosurgery is a safe and effective alternative treatment for trigeminal neuralgia and is associated with a particularly low rate of hypesthesia.

Pituitary apoplexy: do histological features influence the clinical presentation and outcome?
A retrospective analysis of a contemporary series of patients with pituitary apoplexy was performed to ascertain whether the histopathological features influence the clinical presentation or the outcome. ⋯ The patients who presented with histological features of pituitary tumor infarction alone had less severe clinical features on presentation, a longer course prior to presentation, and a better outcome than those presenting with hemorrhagic infarction or frank hemorrhage. The endocrine replacement requirements were similar in both groups.

Endoscope-assisted infratentorial-supracerebellar approach to the third ventricle: an anatomical study.
The authors studied the microsurgical anatomy and endoscopic features of the pineal region and third ventricle to describe a combined microsurgical-endoscopic infratentorial-supracerebellar approach to the posterior third ventricle. Such an approach exposes the pineal gland and its complex neurovascular structures so that the third ventricle can be reached through a minimally invasive parapineal incision. ⋯ The infratentorial-supracerebellar approach to the third ventricle follows a natural corridor and requires minimal retraction and resection of critical neural structures. With the use of the endoscope, an unsurpassed view into the third ventricle from a posterior perspective is obtained.

Pituitary apoplexy in the magnetic resonance imaging era: clinical significance of sphenoid sinus mucosal thickening.
The authors report their experience with pituitary apoplexy and evaluate the clinical significance of sphenoid sinus mucosal thickening found on magnetic resonance (MR) imaging. ⋯ Thickened sphenoid sinus mucosa may correlate with higher grades of pituitary apoplexy and worse neurological and endocrinological outcomes.
