The aim of our study was to compare the health care utilization and outcomes after surgery for anterior cranial fossa skull base meningioma (AFM), middle cranial fossa skull base meningioma (MFM), and posterior cranial fossa skull base meningioma (PFM) across the United States. ⋯ Overall payments (at 12 months and 24 months) and 90-day payments were not different among the cohorts. Patients with PFM had longer hospital stay and higher complication rate and were less likely to be discharged home with higher utilization of outpatient services at 12 months and 24 months.

Rathke cleft cysts (RCCs) are benign cysts arising from the pars intermedia as a result of incomplete obliteration of the Rathke pouch during development of the pituitary gland. The most common presenting symptoms are headaches, visual disturbances, and endocrinopathies. Recurrence of RCCs after surgical treatment is a well-known phenomenon after surgery with reported recurrence rates as high as 30%. Various methods have been employed to reduce the rate of recurrence. Complete cyst wall resection has been associated with increased rates of perioperative cerebrospinal fluid leak, diabetes insipidus, and carotid injury, while inconsistently demonstrating reduced recurrence rates. Marsupialization, in which the cyst cavity is widely exposed and left open with or without a fat graft suspension, has similarly shown increased morbidity without clear improvement in outcomes. We report here the use of a steroid-eluting sinus stent to maintain patency of the cyst opening. ⋯ Recurrent RCCs are challenging to manage. Strategies to reduce recurrence are typically associated with higher risk and varying success. Stent placement represents a simple, low-risk method of potentially maintaining patency of cyst fenestration.

Numerous studies have reported that irregular alteration of facet orientation (IAFO) is associated with lumbar disc herniation (LDH) in adolescents. The present study investigated the association between IAFO and degenerative lumbar spondylolisthesis (DLS) at the L4-5 segment. ⋯ The data presented here demonstrate that LSL, which is an irregular alteration of facet joint orientation, is associated with the degenerative lumbar spondylolisthesis at L4-5.

Pituitary stalk sectioning is only essential in cases of craniopharyngioma originating from the stalk or metastatic tumor to the stalk. Some patients can discontinue postoperative antidiuretic hormone (ADH) supplementation with special conditions. ⋯ Total removal was achieved in 91% of all cases. Half of the patients could discontinue ADH supplementation, which was associated with preservation of thyroid function. The findings of hypothalamic enhancement on postoperative MRI may be associated with recovery from DI.

A well-documented association exists between the vasa vasorum and vasopathologies, including atherosclerosis. However, information on the role of the vasa vasorum during vascular degenerative changes of vasospasm after subarachnoid hemorrhage (SAH) is insufficient. ⋯ The vasa vasorum and their vasospasm play a crucial role in the pathogenesis of basilar artery degeneration in the vasospasm following SAH.
