Unsuspected funiculitis and acute epididymitis in 53-year-old man with history of urolithiasis, fever, and left-sided abdominal pain radiating to the ipsilateral flank and groin. CT (a–c) did not confirm clinical suspicion of acute pyelonephritis. Subtle thickening and vascular engorgement (arrowheads) were noted along the left spermatic cord, plus faint hyperenhancement of the ipsilateral epididymal head (thin arrow in c). Additional colour Doppler ultrasound (CD-US) confirmed inhomogeneously hypoechoic (e), hypervascularised (f) epididymal head (calipers). Antibiotics effectively treated Escherichia coli infection [Partially reproduced with permission from Ref. [10]]
