An epidermoid cyst arising from diploic space in the skull can cause an intracranial mass effect with compression of the underlying venous sinuses. ⋯ Development of diploic venous drainage contributed to avoidance of critical intracranial hypertension during slow growth of a torcular epidermoid cyst.

Previous research has shown a strong correlation between the Ki-67 proliferation index and grade of malignancy in astrocytoma. Ki-67 has also shown encouraging results as a prognostic marker for patients' overall survival (OS). We focus on whether the index is linked to the appearance of glioblastoma on pretreatment magnetic resonance imaging (MRI) or to OS. ⋯ The unique appearance of every glioblastoma on MRI seems to be independent of the Ki-67 index. Furthermore, the Ki-67 index did show a distinct prognostic value for OS within our cohort at a cutoff value of 20% for Ki-67.

Dysphagia is a common complication after anterior cervical discectomy surgery (ACDS). Recent studies have shown that reducing the endotracheal tube cuff pressure, local irrigation with methylprednisolone, and minimizing the pharynx/esophagus retraction can decrease the incidence of postoperative dysphagia after ACDS. This is the first study assessing the efficacy of all these 3 measures simultaneously. ⋯ Postoperative dysphagia occurs frequently after ACDS. We show that the adoption of preventive measures during surgery can reduce the rate of dysphagia. Future evaluations in a large clinical trial are mandatory.

and importance: Epistaxis is a rare presentation of the ruptured cavernous carotid aneurysm (CCA) especially nontraumatic type. Both endovascular therapies and open surgeries have a role in the treatment with various outcomes, but the standard procedure is not well established. We report a successful high-flow bypass with cervical internal carotid artery ligation for aneurysm repair and review the related literature. ⋯ In cases of massive or recurrent epistaxis without coagulopathy or nasal pathology, a CCA should be considered. Immediate cessation of bleeding is necessary. Flow-preservation bypass with proximal ligation of the parent artery is one of the effective procedures for the treatment of this condition with low morbidity.

Despite the fact that technologic advances and surgical experience expand the use of endoscope in spinal surgery, there are few reports on its application in the management of spinal tumors. We present a case report of intradural extramedullary tumor excision with the percutaneous full endoscopic translaminar approach. ⋯ This report supports that full endoscopic spinal intradural extramedullary mass excision may give good results in selected cases and in experienced hands.
