The middle meningeal artery (MMA) is a major dural vessel that plays a significant role in developing chronic subdural hematomas (cSDH). Understanding its variable anatomy is essential for the effective management of cSDH and the prevention of complications. ⋯ The most common configuration of MMA was Adachi-type IC. The MMA most often originated from the maxillary artery. The anterior branch of the MMA was typically dominant, and the posterior branch most frequently originated from the distal segment. There was no significant impact of Adachi type on treatment results or fluoroscopy time.

Suprasellar hypothalamic-opticochiasmatic glioma (HOCG) and craniopharyngioma (CP) have similar appearances on conventional magnetic resonance imaging (MRI) and are difficult to distinguish. Moreover, these tumors are situated near vital structures like the optic chiasm and hypothalamus, rendering conventional surgery susceptible to significant complications. We mainly discussed the surgical application value and diagnostic value of diffusion tensor imaging (DTI) in HOCG and CP. ⋯ DTI enhances the accuracy of HOCG and CP differentiation. Furthermore, patterns of tractography described in this study assist neurosurgeons in delineating the surgical pathway and tumor resection range without damaging important fiber bundles, thereby avoiding permanent neurological deficits and improving survival quality for patients.

Areas of increased signal intensity, known as T2 hyperintensities (T2Hs), observed on T2-weighted magnetic resonance imaging (MRI) scans, are linked to a spectrum of brain abnormalities in children with neurofibromatosis type 1 (NF1). Defining the radiological characteristics that distinguish non-neoplastic from neoplastic T2Hs in children with NF1 is crucial. Then, we could identify lesions that most likely to require oncologic surveillance. ⋯ Low-risk and medium-risk tumor lesions can both be classified as unidentified bright objects(UBOs).UBOs constituted the majority of T2Hs in children with NF1. High-risk tumor lesions should be considered as probable tumors.With the application of standardized radiologic criteria, a high prevalence of probable brain tumors will be identified in this at-risk population of children, which underscores the importance of vigilant and appropriate oncological surveillance to ensure timely detection and intervention for these tumors.
