Abstract:

To understand the CT imaging features of epididymal tuberculosis, the author analyzed 56 patients with epididymal tuberculosis admitted to Kunming Third People’s Hospital from September 1, 2020 to October 31, 2021, who were diagnosed with pathology, bacteriology or effective with anti-tuberculosis treatment.The results revealed the median age of 56 patients with epididymal tuberculosis was found to be 42 years old, and 37 cases (66.1%) had symptoms of scrotal swelling and pain. Among them, 9 cases (16.1%) were combined with scrotal skin sinus tract formation. The number of cases with combined pulmonary tuberculosis, renal tuberculosis, syringomyelia and testicular involvement were 29 (51.8%), 26 (46.4%), 24 (42.9%) and 15 (26.8%).CT showed the epididymis was thickened in 56 cases (100.0%), multiple lesions in 34 cases (60.7%).The epididymis was involved unilaterally in 32 cases (57.1%), and the epididymis was calcified in 8 cases (14.3%). The number of cases with only nodular enhancement, only rim enhancement and both were 23 (41.1%), 19 (33.9%) and 14 (25.0%), respectively, on CT-enhanced scans of epididymal lesions in the portal vein phase. It is believed that patients with epididymal tuberculosis mostly have scrotal swelling and pain, and can be combined with pulmonary and renal tuberculosis. CT scans mostly show unilateral epididymal involvement with multiple lesions and nodular or rim enhancement on enhancement CT scans, which have certain CT imaging characteristics.
