AIMS AND OBJECTIVES The main aim of the study was to identify the prevalence, lobar distribution of neurocysticercosis in a suburban and rural centre of southern Karnataka. Its distribution in male and female population, distribution among various age groups, distribution in lobes, describe its stages, and presence of perilesional oedema. MATERIAL AND METHODS The study was conducted in the Department of Radiodiagnosis, MVJ Medical College and Research Hospital, Bangalore, for a period of 6 yrs. from January 2009 to December 2015. Data collection was prospective. A computer-assisted search of all the reports of CT brain with the diagnosis of NCC was conducted within the departmental database. A total of 198 patients with NCC were identified and the study was conducted. RESULTS Total 4582 CT studies of brain were reviewed. 198 cases of neurocysticercosis (4.3%) were detected. 115 were males and 83 were females. The age range was 8 to 70 years with a mean age of 30 years. The number of patients under age 20 years (n=46) was more compared to the adult patients. Maximum numbers of patients were seen in 41 to 50 years age group followed by 51 to 60 years. Stage 2 of the disease was noted to be predominant in our study with 61 cases (30%) followed by stage 4. However, individual cases showing multiple stages of NCC were observed in 56 cases. Parietal lobe was more commonly involved followed by temporal, frontal, and occipital lobe. Multiple stages of the NCC in individual cases were seen in 56 cases. The presence of an eccentric enhancing scolex was noted in 57 cases. CONCLUSION The prevalence of neurocysticercosis in our study over a period of six years is 4.3% and it is more commonly observed in the paediatric age group (23.2%) and in male sex (58%).
