Brucella and non-Brucella epididymo-orchitis: comparison of ultrasound findings

Ali Haydar Baykan, Hakan Sezgin Sayiner, Ibrahim Inan


Aim: In brucellosis the male genitourinary system can be affected in a small number of patients. In this study we aimed to identify, discuss and compare the radiologic findings of 24 cases with Brucella epididymo-orchitis (BEO) and 285 cases with non-Brucella epididymis orchitis (NBEO).

Material and methods: The study had a retrospective design. The area of involvement, side of involvement (left, right or bilateral), presence of abscess, hydrocele and testicular involvement pattern were analyzed and compared between the BEO and NBEO cases.

Results: The median age of the included cases was 33 years, with a minimum of 0 and maximum of 89. Epididymo-orchitis and isolated orchitis were more frequent in BEO cases while isolated epididymis involvement was more common in patients with non-BEO (p=0.0117). Bilateral involvement was present in 20.8% and 4.6% cases in the BEO and non-BEO groups, respectively (p=0.008). The frequency of abscess was significantly higher in BEO cases (p=0.003).

Conclusion: Although the radiological indications of BEO are similar to those of other types of epididymo-orchitis, abscess formation, bilateral involvement and testicular involvement contribute significantly to diagnosis
