Article Abstract
Mega cistera magna (MCM) is a brain development abnormality that occurs in 1% of radiographic images. It occurs when the transverse dimension of the cerebellospinal reservoir is greater than 10 mm. It is the most important reservoir in the cranial cavity. From the front it is limited by the extended medulla, from the rear by the dura mater, and from the top by the cerebellum. Isolated anomalies in the structure of this brain region often do not cause any clinical symptoms. However, more and more attention is paid in research on the participation of the cerebellum in the regulation of cognitive and affective processes. These processes, in turn, may also be related to the regulation of sexual life. The aim of the study is to present the psychosexual functioning of a man diagnosed with MCM, who is suspected of having committed five sexual offenses. The existence of such a structure of the CNS in conjunction with the analysis of the interview, data from the case files and the results of sexological, psychological and psychiatric examinations, made it possible to evaluate the limitation of the respondent's ability to direct his conduct during the alleged acts, while maintaining the ability to recognize their significance.
Aim: To retrospectively evaluate the cranial magnetic resonance imaging (MRI) features and determine the incidence of intracranial arachnoid cysts (ACs) based on sex, age, location, size, affected side, Galassi type, and their association with hydrocephalus, mega cisterna magna (MCM), bone erosion, and midline brain shift in 15,108 patients during outpatient headache evaluations.
Material And Methods: Between 2012 and 2022, cranial MRI scans of 15,108 adult patients aged 20-70 years undergoing outpatient evaluations for headaches were retrospectively reviewed to analyze the features of ACs detected incidentally. Patients who had previously undergone a craniotomy or craniectomy were excluded from the study.
This study examines how the different presentations of posterior fossa arachnoid cysts (PFACs) affect surgical decisions and patient outcomes in children.
A "wait and see" approach is recommended for asymptomatic patients, leading to better outcomes at one year; surgery types like fenestration or shunting show no significant difference in outcomes, but cyst location does matter.
Factors such as patient age, presence of hydrocephalus, and cyst location are crucial in determining the best treatment to reduce complications and improve results after surgery.
* A total of 65 cases were identified, with DWM (41.5%) and MCM (46.2%) being the most common types; the annual incidence rates varied over the years, peaking at 8.75 per 1000 anatomy scans in 2020.

This article discusses the case of an adult woman with comorbid major depressive disorder (MDD) and obsessive-compulsive disorder (OCD). Due to her poor response to initial treatment regimens, a brain computed tomography (CT) was performed, revealing mega cisterna magna (MCM). Subsequently, she responded well to the addition of lorazepam, a benzodiazepine, along with fluvoxamine and quetiapine XR.
