Extent of resection (EOR) constitutes a crucial factor for patient prognosis in surgery of brain metastases (BMs). According to early studies using postoperative magnetic resonance imaging (MRI), an unexpected residual tumor was not uncommon. Knowledge of potential risk factors for incomplete BM resection would be of major importance to optimize surgical strategies. The aim of this study was to evaluate EOR in a large cohort and analyze potential risk factors for incomplete BM resection. ⋯ Our data indicate that postoperative MRI is able to detect a high portion of unexpected residual tumors after surgery of BMs. Preoperative tumor volume in particular represents an important risk factor for incomplete resection, and hence neurosurgeons should pay special attention to avoid residual tumor tissue.

The impact of household economics on outcomes is not well understood. We examined the relationship of income and surgical outcomes, after controlling for numerous patient characteristics. ⋯ Patients matched on a multitude of characteristics, of lesser household income, had higher long-term mortality after brain tumor resection. Further understanding of this disparity should be sought and differences mitigated.

O-arm computer navigation-assisted technology (OACNAT) has been widely used in the treatment of thoracic ossification of ligamentum flavum (TOLF) in recent years, but there are few in-depth studies on the safety and effectiveness of this approach. The purpose of this study was to investigate the clinical effect of accurate surgical treatment for TOLF with OACNAT. ⋯ The use of OACNAT accurately located the position, size, shape, and boundary of ossification of the ligamentum flavum during the operation, which could guide accurate decompression and improve the accuracy of pedicle screw placement. This approach not only reduced the incidence of incorrect segmental localization and incomplete or excessive decompression but also reduced the risk of related complications and improved the accuracy, safety, and effectiveness of the operation.

Brain metastasis is rare in patients with hepatocellular carcinoma (HCC). The combination of an anti-programmed death 1 inhibitor and an anti-vascular endothelial growth factor drug provides therapeutic opportunities for refractory patients. So far, there are no data on the efficacy of these combined therapies for patients with HCC brain metastasis. ⋯ This case report highlights the efficacy of toripalimab and apatinib in the management of brain metastasis from HCC.

Congenital intranasal encephaloceles (ECs) are rare malformations of the pediatric age, complex to diagnose and treat, above all if associated with genetic syndromes or concomitant dysmorphisms. The aims of the study were to report our experience in managing nasal ECS in children, to evaluate the efficacy and safety of the transnasal endoscopic repair, and to analyze in an overall way the surgical long-term outcomes. Moreover, we sought to contribute to the debate on pathogenesis of ECs, investigating possible related risk factors described in the literature. ⋯ Endonasal endoscopic management of congenital ECs is feasible in children, although regular long-term follow-up is essential. Furthermore, the surgical approach does not seem to affect patients' development and quality of life, although more studies and validated questionnaires are needed. No recurrent risk factors were observed able to justify a certain etiologic relation.
