To analyse the computerised tomography (CT) imaging features and diagnostic value of seminal duct tuberculosis (TB). The imaging data of male patients with ejaculatory duct TB who underwent surgical treatment in our hospital from 1 January 2019 to 31 December 2019 were retrospectively analysed. Through CT images, seminal duct TB was divided into different types, and the CT image features of different types of TB were analysed. The differences in diagnosis between CT and pathological results were compared. According to the CT manifestations of TB of the intrapelvic segment of seminal duct TB, this disease could be divided into an intra-tubular calcification type, a lumen dilatation and effusion type and a wall thickening type, among which 6 cases (15.8%) were intra-tubular calcification types, 14 cases (36.8%) were lumen dilatation and effusion types and 18 cases (47.4%) were wall thickening types. The diagnostic efficacy of CT in the diagnosis of ejaculatory duct TB: sensitivity = 63.89% (23/36), specificity = 80.01% (44/53), accuracy = 75.28% (67/89), positive predictive value = 51.87% (43/109), negative predictive value = 77.19% (44/57) and kappa = 0.558. CT has high sensitivity and specificity in the diagnosis of seminal duct TB. The classification of seminal duct TB using CT images is of great significance for the diagnosis and treatment of the disease.
