To analyze whether multifidus degeneration has a relationship with degenerative lumbar spinal stenosis (LSS). ⋯ Multifidus degeneration, including reduced volume, increased fatty infiltration, and bilateral muscle asymmetry, has an association with LSS.

The coincidence of parasellar aneurysms (IAs) and anterior skull base (ASB) lesions, while rare, presents a management challenge. IAs embedded within, or adjacent to, ASB lesions are at risk in the perioperative period and may have unique presentations, natural histories, and outcomes. The objective of this study was to outline management options and nuances in patients with coexisting IAs and ASB lesions. ⋯ Management decisions for patients with coincident IA and ASB lesions require careful, individualized treatment plans. Coil embolization is well tolerated and does not delay surgery, except in cases requiring stent placement. Inadvertent intraoperative rupture of an adjacent IA during anterior skull base surgery may be treated with emergent coil embolization, flow diversion, or carotid sacrifice, but adequate preoperative planning can reduce this risk.

Percutaneous endoscopic lumbar discectomy (PELD) with remarkable advancements has led to successful results comparable with open discectomy; however, its application in herniated disc (HD) with migration is still challenging and technically demanding. The purpose of this study is to propose various strategies for PELD according to HD with migration. ⋯ An appropriate strategy for PELD is important for successful removal of HD considering the extent of migration and direction.

The dense and complex distribution of neural structures in the brainstem makes it challenging to understand their real configuration. We used the fiber microdissection technique to show the course of the medial and lateral lemnisci within the brainstem. Although these structures seem anatomically alike, they are functionally distinct. ⋯ Using the fiber microdissection technique, we were able to define a general perspective of the topography and architecture of the medial and lateral lemnisci in the brainstem. This perspective should be incorporated into interpretations of magnetic resonance imaging techniques, recognizing both their benefits and limitations. It should also be applied to surgical planning and strategies to achieve a safer and more precise microsurgical procedure.

The Feasibility Analysis for Treatment of Infancy Giant Intracranial Benign Tumor by Delayed-Operation.
The survival rate and prognosis in infants with giant intracranial tumors are significantly worse than in older children. This study aimed to analyze the feasibility of delayed operation for infants with giant intracranial benign tumor by evaluating the initial clinical presentations, expectant treatment measures, perioperative vital signs, and recuperation after surgery. ⋯ Delayed operation enabled infant patients to gain a better physical state, with a stage of full preoperative preparation that may reduce intraoperative/postoperative morbidity and mortality.
