Diffusion tensor magnetic resonance imaging for predicting the consistency of intracranial meningiomas.
The ability of preoperative MRI-sequences to predict the consistency of intracranial meningiomas has not yet been clearly defined. We aim to demonstrate that diffusion tensor imaging (DTI) improves the prediction of intracranial meningiomas consistency. ⋯ FA value and MD and FA maps are useful for prediction of meningioma consistency and, therefore, may be considered in the preoperative routine MRI examination of all patients with intracranial meningiomas.

Gamma Knife radiosurgery for brainstem cavernous malformations: should a patient wait for the rebleed?
The effectiveness of stereotactic radiosurgery (SRS) for cavernous malformation (CM) has not been fully assessed. Consequently, observation is usually recommended when a bleeding CM is initially discovered. Recurrent bleeding occurs with CMs, and these repeat hemorrhages can result in additional morbidity. ⋯ In this study, GKS was demonstrated to be a safe and effective alternative treatment for brain stem CMs that resulted in a reduction in the AHR. Consequently, we suggest that even CM patients who have suffered only a single bleed should not be contraindicated for SRS.

Extended endoscopic endonasal approach for recurrent or residual adult craniopharyngiomas.
The aim of this study was to evaluate the effectiveness of the extended endoscopic endonasal transsphenoidal approach (TSA) for recurrent or residual craniopharyngiomas, focusing on the extent of tumor resection and complications resulting from surgery at a single institution. ⋯ The extended endoscopic endonasal transsphenoidal approach is an effective and safe surgical approach for treating recurrent or residual craniopharyngioma.

Peripheral nerve stimulation by 'sandwich' paddle leads: technical note.
Recently, there has been a burgeoning interest in the utility of peripheral nerve stimulation (PNS) for a variety of chronic focal neuropathic, musculoskeletal and visceral pain conditions. If the source of pain is directly related to a single peripheral nerve, surgical exposure and placing a paddle lead on the nerve are most effective. ⋯ In selected cases where an open surgical PNS lead needs to be placed, the 'sandwich' technique can be used to augment the stimulation without additional morbidity. Although occasionally used in practice, this technique is still unreported.
