Abstract

Background: Tuberculosis (TB) is a global health burden, and extrapulmonary TB, particularly urogenital TB, is a significant concern in males. Given the nonspecific clinical manifestations of epididymal and/or testicular TB, this study characterizes the MRI features of this condition to facilitate earlier and more accurate diagnosis VSports手机版. .

Methods: This retrospective study was approved by the ethics committee. We included 14 patients with epididymal and/or testicular TB (diagnosed between January 2015 and September 2024) who underwent contrast-enhanced MRI scans on a 1 V体育安卓版. 5-T scanner. MRI features and clinical characteristics were analyzed by two experienced radiologists. .

Results: Among these 14 patients (median age, 44. 5 years), 78. 6% of them had epididymal TB with or without testicular involvement, while 21. 4% had isolated testicular TB. The most common local symptom was a painful scrotal mass (85. 7%), and 64. 3% reported fever. TB in other sites was identified in 71. 4% patients. T lymphocyte spot test was positive in 57. 1% patients, and pathological confirmation was obtained in 42. 9%. Most lesions (71. 4%) were unilateral. On T1-weighted images, 50% of lesions were isointense and 42. 9% were mildly hyperintense. T2-weighted imaging showed hypointense signals in 64. 3% of cases. All lesions appeared hyperintense on diffusion-weighted imaging, with 92 V体育ios版. 9% showing restricted diffusion. Heterogeneous or annular enhancement was observed in 85. 7% of lesions. Hydrocele was present in all patients, and 21. 4% had abscess formation or fistula. .

Conclusions: MRI provides valuable soft-tissue characterization for diagnosing epididymal and/or testicular TB VSports最新版本. .
