Introduction: Hydrocephalus is characterized by imbalance of cerebrospinal fluid formation and absorption. It is manifested as a dilatation of the ventricular system. Computed tomography (CT) is useful in determining the ventricular size and shape as well as the amount of the cerebral cortex present in the evaluation of suspected hydrocephalus. Aim and Objectives: Detection of hydrocephalus and determining the cause of hydrocephalus. Differentiating communicating from noncommunicating (obstructive) hydrocephalus. to assess the severity of the hydrocephalus and seek for any consequences. Materials and Methods: This prospective study included 50 patients referred to the Acharya Vinoba Bhave Rural Hospital, Sawangi (Meghe), Wardha, for 1 year. Patients clinically diagnosed with hydrocephalus were included in the study. Multidetector CT (MDCT) imaging was performed on Siemens 16 Slice MDCT machine. Multiplanar reformation and three-dimensional reconstruction were done wherever necessary. Results: 20% were diagnosed to have meningitis, 10% had Intraparenchymal haemorrhage and Intraventricular extension, 12% had aqueduct stenosis, and 12% had communicating hydrocephalus. In the study, 40% of them had communicating-type hydrocephalus or extraventricular obstructive hydrocephalus and 60% had obstructive hydrocephalus. On the CT scan, it was observed that at the lateral ventricle, dilatation was observed in four regions. Frontal horn dilatation (98%), body dilatation (98%), and 100% dilatation were seen at the temporal horn and occipital horn. Among 100 patients, 14% had cortical thinning and thus were classified as severe hydrocephalus with a poor prognosis, and 20% had periventricular edema. Conclusion: CT is the best means of obtaining images as it is easily available, fast, reliable, and compatible with standard life support devices.
