Analysis of nonmetric cranial variants has been essential for identifying the human population through osteologic analysis and genetic affinities. This study aimed to examine the nonmetric cranial variants to evaluate differences among sex and side correlations in Anatolian dry skulls. This study was carried out on 50 Anatolian adult dry human skulls (22 males, 28 females) with suitable features (nonfractured and/or with necessary features) out of a total of 97 dry skulls. After sex analysis, each skull was photographed from the norma frontalis, lateralis, inferior, and superior. Eleven nonmetrical cranial variants were investigated. The cranial variants and side incidences were analyzed to determine their sex differences and interside correlations. After the classification, traits were marked as "present" or "absent" on the charts. Some variants in female crania were seen more frequently than in males. Most of the variants such as the supraorbital notch, infraorbital and zygomaticofacial foramen, showed high correlations between the right and left sides. Overall, there were no statistically significant sex or side differences found in the Anatolian crania.

Background And Objectives: The coexistence of complete carotico-clinoid bridge (CCB), an ossification between the anterior (ACP) and the middle clinoid (MCP), and an interclinoidal osseous bridge (ICB), between the ACP and the posterior clinoid (PCP), represents an uncommonly reported anatomic variant. If not adequately recognized, osseous bridges may complicate open or endoscopic surgery, along with the pneumatization of the ACP, especially when performing anterior or middle clinoidectomies.
Methods: According to Preferred Reporting Items for Systematic Reviews and Meta-Analyses for Scoping Reviews guidelines, a systematic scoping review was conducted up to June 5, 2023.

Introduction: The MAPT gene encodes Tau, a protein mainly expressed by neurons. Tau protein plays an important role in cerebral microtubule polymerization and stabilization, in axonal transport and synaptic plasticity. Heterozygous pathogenic variation in MAPT are involved in a spectrum of autosomal dominant neurodegenerative diseases known as taupathies, including Alzheimer's disease, Pick's disease, fronto-temporal dementia, cortico-basal degeneration and progressive supranuclear palsy.

: The caroticoclinoid bar (CCB) or caroticoclinoid foramen (CCF) represents a well-described ossified variant of the skull base. It corresponds to an osseous bridge (resulting after homonymous ligament ossification) between the anterior and middle clinoid processes (ACPs and MCPs) surrounding the internal carotid artery (ICA)'s cavernous segment. Although extensive research has been performed on this clinically significant entity, only a few studies have been conducted on its effect on the ICA.

A prominent subarachnoid space (SAS) in infants under 24 months is a very common finding and is a normal variant that can be associated with macrocephaly. This must be differentiated from various pathological conditions that also cause a prominent SAS, including a reduction in brain volume, obstruction to the cerebrospinal fluid (CSF) or malformations of the skull. The inappropriate labelling of normal SAS prominence as enlargement due to pathology and misrepresentation of published literature by some author groups has created confusion medicolegally, contributing to inappropriate conclusions that a normal prominent SAS may cause subdural haemorrhage (SDH) and brain injury.

We report a 28-year-old G2P0 at 24 weeks 5 days who presented for evaluation secondary to suspected skeletal dysplasia in her fetus. Fetal ultrasound imaging demonstrated foreshortened long bones by 9-10 weeks, multiple bowing deformities and fractures, 11 foreshortened paired ribs with fractures, decreased skull mineralization, frontal bossing, enlarged cavum septum pellucidi, and severe fetal growth restriction (< 2%). Findings were concerning for life limiting condition with thoracic circumference < 2.
