Background: A detailed ultrasound examination of the fetal urinary tract as part of prenatal care is important to detect possibleabnormalities. Early diagnosis can prevent more serious damage such as loss of kidney function. Interstitial nephritis cancompromise renal functionality. Also, acute interstitial nephritis is a frequent cause of acute kidney injury and can becomechronic if not treated. Besides, a renal biopsy can help in the diagnosis and at the staging of the disease. Therefore, thisreport aims to describe the ultrasonographic findings of the renal tissues in a canine fetus affected by interstitial nephritis.Case: Gestational ultrasound evaluations were performed in a female Pug, at the 25th, 45th, and 58th gestational days.Ultrasound examination was performed with a 9.0 MHz linear transducer and a high-resolution digital transducer with afrequency standardized at 17.0 MHz. During the first evaluation, embryonic vesicles were detected and were compatible withthe gestational period. At 45 days of gestation, some abnormalities were observed in the kidneys of one of the fetuses, suchas increased cortical echogenicity, cortical thickening, loss of corticomedullary ratio (1:1), renal pelvis and ureter dilatationby echogenic content. Biparietal and abdominal diameters were also lower than that from the other fetuses, which did notshow abnormalities, being compatible with the estimated gestational age. However, the heart rate was similar among allfetuses. On the 58th day, we observed in the underdeveloped fetus that both kidneys still presented the abnormalities seenpreviously, in addition to the presence of a cystic structure in the right kidney, in the cranial...(AU)
