Abstract: The cerebral aqueduct and the central medullary canal connect the fourth ventricle of the brain to the third ventricle, making it a crucial component of the ventricular system. Obstructive disease of the brain's limbic system is rather prevalent. Many cases are brought on by tumours coming from the fourth ventricle or the brain matter around the ventricular cavity. The majority of cases require surgical intervention. The ventricle's structure and the system's fluid circulation are altered by these tumours. There is a wealth of information in the literature about how patients with mental health conditions, particularly those with schizophrenia, modify the ventricular system's capacity and alter the shape and symmetry of the ventricles. According to a study, thalamic shrinkage, particularly in the medial nuclei and the surrounding striatum and insular cortex in schizophrenia patients, appears to be a significant factor in ventricular enlargement. [1] A medical imaging technology called magnetic resonance imaging (MRI) creates images of the anatomy and physiological functions of the body in both health and sickness. It creates images of the inside organs of the body using a magnetic field and radio wave energy pulses. In contrast to what may be observed with an X-ray, ultrasound, or computed tomography (CT) scan, MRI provides diverse information on the architecture of the body. Additionally, it could reveal issues that conventional imaging techniques are unable to detect. Strong magnetic fields, radio waves, and field gradients are used by MRI scanners to produce images of the body's organs. [2]
