Original Article


Very limited information is available on the trans-scrotal ultrasonography of cross-bred Ongole bulls with scrotal swelling in India. The present study was carried out on the bulls presented to the hospital with the history of scrotal swelling. Haematology revealed increased leucocyte count, neutrophilia and mild reduction in haemoglobin levels. Microscopic evaluation of the semen revealed abnormal morphology and the presence of the dead spermatozoa. Trans-scrotal ultrasonography helps in the differential diagnosis of scrotal disorders and to identify the appropriate aetiology for developement of the condition. On ultrasonography, all the bulls showed abnormal scrotal morphology. Among these, one had the presence of normal echogenicity testes which are surrounded by the anechoic fluid which will cover by a hyper echoic scrotal skin. The second one showed the anechoic fluid was mixed with the hyper echoic fibrinous threads and degenerative changes in one testis. Third bull showed the diffused hyper echoic threads scattered within the anechoic fluid and different echogenicity of the two testes. In conclusion, trans-scrotal ultrasonography is helpful in the differential diagnosis of the scrotal swells in large animals.
