Case Reports
"Sentinel seizure" as a warning sign preceding fatal rupture of a giant middle cerebral artery aneurysm.
Sentinel headache is a well-known warning sign preceding subarachnoid hemorrhage (SAH) caused by rupture of an intracranial aneurysm. New-onset seizure or "sentinel seizure" preceding aneurysmal SAH, however, is uncommon. ⋯ As with sentinel headache, new-onset seizures in patients with unruptured intracranial aneurysms might prompt immediate treatment to prevent imminent SAH with its subsequent high morbidity and mortality.

Case Reports
DTI tractography detecting isolated oculomotor nerve damage after brain traumatic injury.
A 24-year-old woman was hit by a bus and suffered an isolated complete oculomotor nerve palsy. Computed tomography scan did not show a skull base fracture. ⋯ Diffusion tensor imaging fiber tractography confirmed a sharp arrest of the left oculomotor nerve. This recent imaging technique could be of interest to assess white fiber damage and help make a diagnosis or prognosis.

A 40-year-old man was referred to our center with a 4-month history of progressive quadriparesis. Previous brain imaging revealed no abnormality. Magnetic resonance imaging (MRI) with contrast of the cervicothoracic spine revealed 2 heterogeneously enhancing lesions at the level of C3-C5 and T2-T4 (A); T1- and T2-weighted MRI showed hypointense and hyperintense lesions, respectively, which is characteristic of spinal cord astrocytoma (B and C). ⋯ Though resection was attempted, surgery was aborted due to hemodynamic instability and signal changes in neuromonitoring. The patient stabilized in the intensive care unit and experienced slight improvement in upper extremity strength. After discharge without further complications, the patient was expected to return for further adjuvant therapy/surgical planning but unfortunately passed away 1.5 months after his operation, most likely to rapid disease progression.

The nomenclature adopted for endoscopic medial maxillectomies (EMMs) is exceedingly heterogeneous. The aim of this study was to objectively measure surgical exposure in a preclinical anatomic setting to validate a classification for modular EMMs. ⋯ This modular classification of EMMs, based on quantitative analysis in a preclinical setting, should allow for better personalized preoperative surgical planning and provides standardization of nomenclature.

A 56-year-old man was admitted to our hospital with intermittent right facial numbness for 1 year and instability on walking for 6 months. Magnetic resonance imaging revealed an ovoid and well-demarcated intra-axial pontine lesion. ⋯ Preoperative symptoms resolved completely 3 months after surgery and no evidence of recurrence was found during 3 years of follow-up. Although total resection of enterogenous cysts is recommended, cyst fenestration may be useful if the cyst is adherent to vital neurovascular structures.
