To investigate the possible influence of risk factors on seizure outcome after surgery for drug-resistant nonlesional temporal lobe epilepsy (TLE). ⋯ Many patients with drug-resistant nonlesional TLE responded favorably to surgery. The only factor predictive of seizure outcome after surgery was a history of febrile seizure in childhood. It is critical to distinguish among different types of TLE when assessing outcome after surgery.

Comparative Study
Microvascular decompression for trigeminal neuralgia: the role of mechanical allodynia.
This study was conducted to determine whether mechanical allodynia (MA) acts as a predictor of outcome after microvascular decompression (MVD) for trigeminal neuralgia (TN) and to discuss the potential pathologic mechanisms involved. ⋯ The presence of MA is a reliable predictor of immediate and long-term outcome after MVD for TN. Compared with the patients without MA, the incidence rate of intraoperative neurovascular compression was higher in MA-positive patients, who were more likely to achieve a better outcome and lower rate of recurrence after MVD for TN. Application of the information in this study will be helpful in patient selection of MVD for TN.

Prospective international cohort trials have suggested that incidental cerebral aneurysms with diameters less than 10 mm are unlikely to rupture. Consequently, small ruptured cerebral aneurysms should rarely be seen in clinical practice. To verify this theory, dimensions and locations of ruptured cerebral aneurysms were analyzed across the state of Tasmania, Australia. ⋯ Despite findings from prospective international cohort trials, small ruptured intracranial aneurysms are common in clinical practice. In consequence, it seems important to identify those patients with small but vulnerable unruptured aneurysms before conservative management is considered.

Review Case Reports
Pure Intrasellar Meningioma Mimicking Pituitary Macroadenoma: MR Imaging and Review of the Literature.
Intrasellar meningioma originating from the sellar floor is extremely rare and is often indistinguishable from pituitary macroadenoma, both clinically and radiologically. Here, we report a case involving a 68-year-old patient with intrasellar meningioma possibly originating from the sellar floor and present a brief review of all previous cases reported in the English literature.
