Development of a delayed acute epidural hematoma (DEDH) represents a rare event, characterized by a high mortality rate. It is defined as an extradural bleeding not evident at the first brain computed tomography (CT) scan performed after traumatic brain injury but evidenced by further radiologic evaluations. ⋯ To the best of our knowledge, this is the first report of a synchronous acute bilateral EDH with the development of a third DEDH located in a separate site. This finding is certainly related to the presence of multiple and bilateral skull fractures. In our experience, we suggest performing an intraoperative CT scan, if available, to early detect the possible development of DEDH.

Gamma Knife radiosurgery (GKRS) outcomes for anterior clinoid process (ACP) meningiomas have not been specifically reported within any meningioma series. We present the initial and largest series in the literature that describes the presenting features, radiosurgery parameters, and radiologic and long-term clinical outcomes for 61 patients with ACP meningiomas treated with GKRS. ⋯ GKRS provides a high rate of tumor volume control for ACP meningiomas as well as a low complication rate. Excellent tumor volume control was associated with smaller tumor size only.

We report a rare case of cervicothoracic intramedullary and extramedullary lipoma. Complete resection of the extramedullary lipoma and almost complete resection of the intramedullary lipoma were performed using a microscope, followed by posterior fusion and internal fixation from C4-T2 to maintain the stability of the cervicothoracic junction. Despite the high risk, it was still necessary to perform the decompression surgery and the surgical results were favorable.

Navigated transcranial magnetic stimulation (nTMS) is being used for different purposes in patients with brain tumors. However, the procedure requires a positive electrophysiological response. For patients with negative response in rest conditions, active motor threshold (AMT) may be used. However, sometimes it is difficult to obtain AMT measures owing to inability of the patient to sustain steady muscle contraction. Herein, we describe a simple method by using a hand dynamometer to obtain AMT measures during nTMS session. ⋯ Although more studies are necessary to validate the method, the hand dynamometer should be considered for patients unable to sustain muscle contraction during AMT measurement.

Morbidity and mortality conferences (MMCs) are now widely implemented in clinical hospitals, but their impact on the education for neurosurgeons remains limited. This prospective study was aimed to assess the efficacy and benefit of MMCs on the education for neurosurgeon. ⋯ Knowledge acquisition from MMCs can significantly reduce "avoidable" morbidity events in both residents and experienced neurosurgeons. The educational effect was more distinct in the residents.
