Magnetic Resonance Imaging Manifestations in 13 Cases of Seminal Vesicle Tuberculosis.

OBJECTIVE

This study aimed to examine the radiographic manifestations of seminal vesicle tuberculosis (SVT) on magnetic resonance imaging to gain a deeper understanding of this disease.

METHODS

The clinical symptoms, general conditions, relevant laboratory tests and radiological data of 13 patients diagnosed with SVT were collected through bacteriological examination. A descriptive analysis was used to explore the composition ratio and rate values of the collected data.

RESULTS

All 13 cases (100.0%) showed isointense signals on TWI and hypointense signals on TWI in the affected seminal vesicles, with the disappearance of the multi-chambered high signal on TWI in normal seminal vesicles. Eight cases (61.5%) showed diffusion restriction on DWI of the affected seminal vesicle and significant enhancement on the contrast scan, whereas five cases (38.5%) showed unrestricted diffusion and mild enhancement on the contrast scan. Patients with significant enhancements exhibited higher counts and neutrophil percentages than patients with mild enhancements, with statistically significant differences ( = 2.196, = 0.030; = 2.781, = 0.003, respectively). The counts and percentage of lymphocytes, CD3T cells and CD4T cells were significantly lower in patients with significant enhancements than in those with mild enhancements, with statistically significant differences ( = -2.196, = 0.030; = -2.928, = 0.002; = -2.928, = 0.002; = -2.928, = 0.002, respectively). Patients with significant enhancements were more likely to have active pulmonary tuberculosis than those with mild enhancements, with a statistically significant difference ( = 0.035).

CONCLUSION

Magnetic resonance imaging reveals distinct radiographic features of SVT, and variations in imaging presentations can indicate a patient's immune status.
