The white fiber and gross anatomy relevant for performing amygdalohippocampectomy through the middle temporal gyrus approach for mesial temporal sclerosis has been depicted by white fiber dissection. ⋯ The middle temporal gyrus is a commonly used approach to perform temporal lobectomy and amygdalohippocampectomy for patients with mesial temporal sclerosis. The anatomy relevant to the approach as presented will aid while performing epilepsy surgery.

A 3-month-old first of dizygotic male twins, born at 34 + 5 weeks gestational age, presented with a 4-week history of increasing head circumference and vomiting. He had a tense anterior fontanelle and a head circumference above the 97th percentile. Magnetic resonance imaging showed large bilateral subdural collection with hemosiderin deposits suggestive of hemorrhage. ⋯ Benign enlargement of subarachnoid space has an assumed autosomal/multifactorial inheritance and predisposes to subdural hemorrhage. Ultimately, no safeguarding issues were raised. Both twins continued to be neurologically stable at 2-year follow-up with head circumferences between the 98th and 99th percentiles.

Dural arteriovenous fistulas draining into an isolated sinus often require a multimodal treatment, with transarterial and transvenous approaches.1-6 However, there is no consensus about the injection technique. Some authors suggest filling the sinus with coils in order to have a compact cast without unnecessary migration of the embolic material. We present a case of a patient with left temporal hemorrhage caused by a dural arteriovenous fistula on the isolated left transverse sinus. In this operative video we demonstrate how the arterial flow control during treatment allows us to obtain a compact cast of the embolic material inside the isolated sinus without coils (Video 1).

Vestibular schwannoma is the third most common benign intracranial tumor that can occur sporadically or be associated with neurofibromatosis type 2 (neurofibromatosis type 2 vestibular schwannoma [NF2-VS]). The aim of this study is to provide a comprehensive bioinformatic analysis of methylated-differentially expressed genes (MDEGs) in NF2-VS. ⋯ Analysis of MDEGs may enrich the understanding of the molecular mechanisms of NF2-VS pathogenesis and lay the groundwork for potential biomarkers and therapeutic targets for NF2-VS.

Hemangioendotheliomas are rare, intermediate-grade malignant tumors in the neuraxis, mainly involving the brain and meninges. Hemangioendotheliomas of the spine have been encountered more often in the vertebral body than the intradural space. Here, we present a rare case of a unique intradural hemangioendothelioma of the lumbar spine; only a few such cases exist in the literature.
