CTICasesDisseminated Tuberculosis with Genitourinary Involvement
Imaging findings
Scrotal ultrasound demonstrates a severely enlarged, hypervascular, and inflamed epididymis. Abdominal CT shows a focal filling defect in the right renal collecting system representing papillitis, and chest CT shows chronic scarring in the right upper lobe along with bronchiectasis and airway-centered nodules.
Key takeaways
Disseminated tuberculosis can seed the genitourinary tract via hematogenous spread from the lungs. Chronic tuberculous epididymitis can present as scrotal swelling that does not respond to standard antibacterial treatment and can be associated with renal collecting system filling defects.
