There are many studies on post-operative cognitive function after surgical clipping (SC) and endovascular coiling (EC) for unruptured cerebral aneurysms, but few reports focusing on possible subclinical damage. The aim of the present study was to detect the subclinical damage after surgical intervention. ⋯ 123IMP-SPECT revealed a statistically significant reduction in ipsilateral CBF in patients who had an uneventful clinical course and no cognitive problems. The subclinical consequence could persist for at least 2 years following SC, and was less pronounced following EC.

Rathke cleft cysts (RCC) are congenital, non-neoplastic sellar cysts derived from remnant of embryonic Rathke's pouch. Presentation of RCC can be incidental however in larger cysts, presentation can be with headaches, visual deterioration and pituitary and endocrine dysfunction. Here we report a rare case of identical twin boys with Rathke cleft cysts highlighting the likely genetically driven development of cyst in this identical twin and need for cranial imaging in identical twins with anomalies of the brain.

Epidural extramedullary hematopoiesis (EMH) is a rare, underreported phenomenon in which hematopoiesis occurring outside of the medullary environment can cause spinal cord compression. In this systematic review, we evaluate clinical characteristics and evidence-based guidelines for clinical management of EMH and present an illustrative case. ⋯ Epidural EMH is a pathology with limited reporting; this systematic review is the most comprehensive to date. Although available case series data were heterogeneous, our analysis suggested that multimodal treatment with surgical intervention was beneficial. Given the young patient population, we recommend prompt surgical management via decompression of the spine because of the associated low risk of complications and recurrence, and better neurological recovery.

This study aimed to integrate intraoperative ultrasound and magnetic resonance imaging (IMRI) with neuronavigation (NN) to create a multimodal surgical protocol for diffuse gliomas. Clinical outcomes were compared to the standard NN-guided protocol. ⋯ Compared to standard NN-guided surgery, multimodal-integrated surgery using NN, IMRI, and intraoperative ultrasound significantly increased the EOR and GTR rates for diffuse gliomas.

Surgical interventions for arachnoid cysts and glioependymal cysts primarily focus on cyst decompression and establishing communication with cerebrospinal fluid (CSF) spaces. However, a standardized surgical strategy for symptomatic convexity cysts lacking surrounding CSF space is still lacking due to the limited number of cases. This systematic review aims to evaluate surgical interventions for symptomatic convexity cysts and proposes a safe and effective treatment approach we have developed. ⋯ Furthermore, the surgery was conducted with the patient fully awake, and the use of electrical stimulation mapping enabled preservation of higher neurocognitive functions, including language, working memory, and spatial cognition, at the puncture site. This novel approach offers advantages such as minimally invasive procedure, preservation of safe brain function, and long-term patency. Further studies are warranted to validate these findings and improve surgical strategies for convexity cysts.
