To evaluate the risk factors of tumor-related epilepsy (TRE) and the relationship between TRE and functional/survival outcomes in patients with high-grade glioma (HGG). ⋯ In patients with HGG, preoperative epilepsy is significantly associated with tumor involvement of the frontal lobe, whereas postoperative epilepsy is associated with preoperative epilepsy and dominant hemispheric location. Also, patients with HGG with preoperative epilepsy have better PFS and OS.

Primary intraventricular hemorrhage (PIVH) is a rare condition in adult patients. PIVH occurs frequently in adult hemorrhagic Moyamoya disease (MMD). Idiopathic PIVH is defined as PIVH without cerebrovascular abnormalities. This study is aimed to compare the baseline characteristics and outcomes of acute MMD-related and idiopathic PIVH. ⋯ Compared with patients with acute idiopathic PIVH, patients with acute MMD-related PIVH have younger age, lower blood pressure, and better renal function. Moreover, patients with acute MMD-related PIVH have lower short-term mortality.

Cerebral arteriovenous malformations (CAVMs) are characterized by altered hemodynamics and associated with angioanatomic changes, such as aneurysms. We encountered a patient with a CAVM-associated dissection of the medial trunk of the posterior inferior cerebellar artery (PICA) instead of an aneurysm. ⋯ This is the first report of a hyperdynamic flow-related dissection of a CAVM-associated feeding vessel. Microsurgical resection of the CAVM allowed for spontaneous resolution of the dissected area by restoration of normal rheodynamics.

Despite increasing use of direct oral anticoagulants (DOACs), guidelines for their perioperative use in spine surgery are still lacking. The main goal of our study was to analyze the occurrence of postoperative bleeding events and possible confounders in patients treated with DOACs who undergo spine surgery. ⋯ Short preoperative discontinuation time of DOACs, even <24 hours, may be justified, considering an increased risk of perioperative packed red blood cell substitution. Care should be taken with patients treated with concomitant blood thinners and patients with pre-existing kidney disease. Postoperative DOAC resumption >72 hours may increase risk of thromboembolic events.

Pituitary adenomas comprise about 3% of all intracranial tumors in pediatric patients. This study examines the role of stereotactic radiosurgery in the management of pediatric acromegaly or patients with Cushing disease (CD). ⋯ GKRS affords reasonable rates of endocrine remission and tumor control in most pediatric patients with functioning adenomas. The most common post-GKRS complication was hypopituitarism, although this occurred in only a few patients. Given the larger at-risk period for pediatric patients, further study is required to evaluate for delayed recurrences and hypopituitarism.
