“…The patient of this report did not present clinical symptomatology or renal dysfunction. Diagnosis was incidental during ultrasonography examination of post ovariohysterectomy bleeding suspect corroborating with the literature (Brückner et al, 2010, Seo et al, 2017).…”

“…This alteration was described in males (Allworth and Hoffman, 1999;Seo et al, 2017), however sexual and racial predilection is not well defined in veterinary literature (Lulich et al, 1987;Brückner et al, 2010). In this report the renal ectopia occurred in a female the opposite to what was said by Allworth and Hoffmann (1999) and Seo et al (2017).…”

“…In Veterinary Medicine only two cases of renal ectopia associated with fusion in the left kidney have been described (Allworth e Hoffmann, 1999;Seo et al, 2017). In another case, right kidney ectopia was detected without fusion (Brückner et al, 2010).…”

“…The obtained images by excretory urography and US were similar to those observed in a report that described a case of right renal ectopia associated to renal fusion on the left abdomen in a feline (Allworth and Hoffman, 1999). However, a recent study used ultrasonography and computed tomography images to diagnose ectopia and renal fusion on the right side of the abdomen (Seo et al, 2017).…”

A 3 year old female feline of mixed breed was sent to the diagnostic imaging sector under suspicion of bleeding due to ovariohysterectomy. An abdominal ultrasonography was performed to confirm the initial suspicion. However, no signs of bleeding were found, instead it was observed that the left renal silhouette had two pelvises and was elongated and larger than normal. The right kidney was not found. Excretory urography was requested to evaluate the condition of the ureters. The final diagnosis was crossed renal ectopia with fusion in an asymptomatic cat with no changes in renal function.

Feline abdominal ultrasonography: what’s normal? what’s abnormal? The kidneys and perinephric space

Practical relevance: Abdominal ultrasound plays a vital role in the diagnostic work-up of many cats presenting to general and specialist practitioners. Ultrasound examination of the kidneys and perinephric space can provide important information on several conditions including chronic renal disease, hydronephrosis and perinephric pseudocyst formation. Clinical challenges: Despite ultrasonography being a commonly used modality, many practitioners are not comfortable performing an ultrasound examination or interpreting the resulting images. Even for the experienced ultrasonographer, differentiating between incidental findings, such as a medullary rim sign, and pathological changes can be challenging. Aim: This review, part of an occasional series on feline abdominal ultrasonography, discusses ultrasonographic examination of the normal and diseased kidney and perinephric space. Aimed at general practitioners who wish to improve their knowledge of and confidence in feline abdominal ultrasound, this review is accompanied by highresolution images and videos available online as supplementary material. A subsequent article will address ultrasonography of the collecting system including the renal pelvis and urinary bladder. Equipment: Ultrasound facilities are readily available to most practitioners, although use of ultrasonography as a diagnostic tool is highly dependent on operator experience. Evidence base: Information provided in this article is drawn from the published literature and the author's own clinical experience.

Case series summary A retrospective multicenter case series of renal fusion anomalies in cats was investigated. The aim of this study was to describe the imaging characteristics (radiography, ultrasonography and CT) of renal ectopia and fusion in cats. A total of 13 feline patients (median age 9 years) were included in this multicentric retrospective study. Ultrasound was available in 12/13 cases, radiographs in 4/13 cases and CT in 3/13 cases. Of the 13 cases, seven were left to right fusions, four were right to left fusions, one was on the midline and one was in the pelvic inlet. Adopting a human classification system, there were five lump kidneys, four disc kidneys, one horseshoe kidney, one caudal ectopia, one L-shaped kidney and one pelvic kidney. In 2/13 cases, additional congenital malformations were noted, including an azygous continuation of the caudal vena cava and a peritoneal-pericardial diaphragmatic hernia. Relevance and novel information This study provides further description of the imaging findings in feline patients with fused renal ectopia. The morphologic characteristics of the fused kidneys in cats appear similar to what is published in the human literature. Renal fusion might be an incidental finding in cats, but further investigations are necessary to determine their clinical relevance.
