Comparative Study
Microsurgery Versus Stereotactic Radiosurgery for Brain Arteriovenous Malformations: A Matched Cohort Study.
Microsurgery (MS) and stereotactic radiosurgery (SRS) remain the preferred interventions for the curative treatment of brain arteriovenous malformations (AVM), but their relative efficacy remains incompletely defined. ⋯ For patients with comparable AVMs, MS and SRS afford similar rates of deficit-free obliteration. Nidal obliteration is more frequently achieved with MS, but this intervention also incurs a greater risk of new permanent neurological deficit.

Evaluation of differences in neuropsychological outcomes in patients undergoing surgical clipping (SC) vs endovascular coiling (EC) for unruptured cerebral aneurysms is essential in guiding patients seeking treatment of asymptomatic cerebral aneurysms. ⋯ Whereas the initial decline in neuropsychological functioning was greater for SC patients, 1 yr after treatment there was no significant difference in neuropsychological outcome among the SC, EC, and healthy control groups.

Liposclerosing myxofibrous tumors (LSMFTs) are rare benign fibro-osseous tumors most frequently occurring in the proximal femur. We report the first case of this rare tumor occurring within the calvarium. ⋯ LSMFT is a rare tumor that should remain on the differential for lesions of the calvarium. When diagnosed, this lesion can be removed with the goal of gross total resection and excellent cosmesis can be achieved.

Hemodynamic factors play a crucial role in the recurrence of intracranial aneurysms after coiling. However, the strongest factor for predicting recurrence remains unclear because each risk factor has been investigated and reported separately. ⋯ The pressure difference in the virtual postcoiling model may be a strong predictor of recurrence after coiling.
