The defining of the normal parameters of spacious relations and symmetry of the ventricular system of the brain depending on the gender and age is currently one of the topical research problems of clinical anatomy. The present research aims to identify the correlation between the morphometric parameters of the fourth ventricle of the brain and the shape of the skull in middle aged people. This is a prospective cohort study. This study was set at the Trinity School of Medicine. A total of 118 normal computed tomography scans of the head of people aged from 21 to 86 years (mean age-48.6 years ± 17.57) were selected for the study. The anteroposterior, transverse diameters, and height of the fourth ventricle were measured and compared in dolichocranial, mesocranial, and brachycranial individuals. The study has shown the presence of a statistically significant difference between morphometric parameters of the fourth ventricle of the brain in dolichocranial, mesocranial, and brachycranial individuals. The morphometric parameters of the fourth ventricle of the brain, such as height, anteroposterior, and transverse diameters, depend on the individual anatomic variability of the skull shape and gender.

SummaryA case of meningioma located in the posterior part of the third ventricle is presented. A review of the common presentations and current trends in management is included.

We present a case of a 4-month-old infant with abnormal eye movements, unusual flat facies, and lack of expression during crying, clinically diagnosed with Möbius syndrome. MR imaging demonstrated absent facial and abducens nerves. A dysplastic right cerebellar hemisphere containing a cleft and multiple clustered cysts was also observed, which, to our knowledge, represents the first documented case of an association between Möbius syndrome and cerebellar dysplasia. A review of pertinent literature is provided.
