A Connectomic Atlas of the Human Cerebrum-Chapter 14: Tractographic Description of the Frontal Aslant Tract.
In this supplement, we show a comprehensive anatomic atlas of the human cerebrum demonstrating all 180 distinct regions comprising the cerebral cortex. The location, functional connectivity, and structural connectivity of these regions are outlined, and where possible a discussion is included of the functional significance of these areas. In this chapter, we specifically address the regions integrating to form the frontal aslant tract.

Microsurgical Resection of Ruptured Large Left Temporo-Occipital Arteriovenous Malformation: 3-Dimensional Operative Video.
A 59-yr-old man presented with intraventricular hemorrhage and was found to have a large temporo-occipital arteriovenous malformation (AVM), Spetzler-Martin grade 4. The preoperative intra-arterial digital subtraction angiography (IADSA) showed the AVM was 4 × 4 cm2, had superficial and deep venous drainage, and was fed by multiple branches of the posterior cerebral artery and middle cerebral artery. Preoperative embolization was done in 4 stages. He underwent a left temporo-occipital craniotomy, mastoidectomy, and retrosigmoid craniotomy with a posterior temporal approach. ⋯ The postoperative IADSA demonstrated total resection. At 3-mo follow-up, he had recovered completely (mRS0). This 3-D video shows the technical nuances of microsurgical resection of a complex large AVM. Informed consent was obtained from the patient prior to the surgery that included videotaping of the procedure and its distribution for educational purposes. All relevant patient identifiers have also been removed from the video and accompanying radiology slides.
