Background: Diagnosing abdominal tuberculosis is still a big problem because of lack of clinical symptoms and signs. Early and precise diagnosis leads to successful therapy and a high chance of survival. Therefore, the study is conducted to find the spectrum of findings in tuberculous peritonitis patients in New Delhi, India. Materials and Methods: An observational cross-sectional descriptive study was done at ABVIMS and associated Dr. RML Hospital in New Delhi at the Department of Radio Diagnosis. The investigation lasted 30 months, from January 2021 to June 2023. Ultrasound imaging of the abdomen was done followed by Dual phase CT acquisition using Siemens somatom drive 256 slice CT. The data were collected from a total of 44 study participants. Results: Half of them 22 (50%) were males. The mean age with SD (standard deviation)of the study population was 42.09 (18.40) years. Mantoux test was positive in 25 (56.8%). On ultrasound examinations, most of the study participants had ascites with septations 19 (43.2%). Uniform and smooth thickening and enhancement of the peritoneal lining was the most commonly observed CT finding at 43 (97.7%), followed by ascites at 42 (94.4%). Conclusion: CT imaging offers an easy and early diagnosis of tuberculous peritonitis. Enhancement of peritoneal lining and ascites were the common findings of tuberculous peritonitis on CT imaging.
