We investigated whether air in the cisterns or ventricles on postoperative computed tomography (CT) (reflecting the opening of the cerebrospinal fluid spaces during surgery) is a predictor of classical or nodular leptomeningeal disease (LMD) after resection of brain metastases. ⋯ Postoperative air in the cisterns or ventricles can predict early classical or nodular leptomeningeal disease.

Interest in the relational anatomy of the anterior neck among spine surgeons increased after the popularization of anterior cervical discectomy and fusion in the 1950s. Five surface landmarks and their relationship to specific spinal levels have been routinely described, comprising the angle of the mandible for the C2-C3 interspace, the hyoid bone for the C3 body, the thyroid cartilage for the C4-C5 disc, and the cricoid cartilage and carotid tubercle for the C6 body. We aimed to investigate the origins of these anatomic relationships and their application in modern practice.

A 37-year-old man with a history of head trauma surgery 8 years previously was admitted because of persistent pulsatile exophthalmos and intracranial murmur. Angiography results showed that blood from the right internal carotid artery flowed directly into the cavernous sinus , with the arterial system above the cavernous sinus not visualized; early visualization of the right venous sinus system; dilation of the right superior ophthalmic vein and the medial canthal vein. ⋯ After a comprehensive preoperative assessment, we chose spring coil embolization treatment, which resulted in the disappearance of symptoms after treatment. Three months later, on follow-up, the patient reported no longer hearing intracranial murmur, and auscultation of the right temporal region showed no abnormal sounds.
