Bilateral multiple cystic kidney disease and renal cortical abscess in a Boerboel

Abstract

Cystic renal disease is rare in dogs and although infected renal cysts have been reported in humans, no report could be found in dogs. A 58 kg, 5-year-old, castrated, male Boerboel presented with weight loss, pyrexia, lethargy and vomiting, 20 months after an incident of haematuria was reported. The initial ultrasonographic diagnosis was bilateral multiple renal cysts of unknown aetiology. The cysts had significantly increased in size over the 20-month period and some contained echogenic specks which could be related to infection, normal cellular debris or haemorrhage. In both kidneys the renal contours were distorted (the left more than the right). The abnormal shape of the left kidney was largely due to multiple cysts and a large crescent-shaped septate mass on the cranial pole of the kidney. Aspirates of the septate mass were performed (left kidney) and the cytology and culture were indicative of an abscess. It is suggested that the previous incident of haematuria provided a portal of entry for bacteria into the cysts resulting in renal cortical abscess formation.

Renal capsulotomy associated with omentopexy for treatment of bilateral perinephric abscess in a bitch: case report

“…These signs also disappeared after surgery and antibiotic treatment. Similar to the animal in our report, dogs described in the literature (LEWIS et al, 1988;AGUT et al, 2004;KITSHOFF et al, 2011;PINTO FILHO et al, 2013) also presented some clinical signs, even if they were unspecific. Such signs include loss of appetite, fever, depression, and abdominal pain.…”

“…One case in the literature describes a dog with systemic inflammatory response syndrome induced by bacterial dermatitis due to S. pseudintermedius (MIN et al, 2014). Finally, in contrast to other cases where dogs had perinephric abscesses associated with renal cysts (KITSHOFF et al, 2011;PINTO FILHO et al, 2013), in this report the dog had perinephric abscesses without renal cysts; this likely improved the prognosis and recovery.…”

“…Two cases describing bilateral perinephric abscess in dogs also had multiple renal bilateral cysts and culture was positive for Escherichia coli (KITSHOFF et al, 2011;PINTO FILHO et al, 2013). Unexpectedly, in the present case the culture was positive for Staphylococcus pseudintermedius, which is commonly found in skin lesions.…”

“…Such signs include loss of appetite, fever, depression, and abdominal pain. Early diagnosis is important to avoid irreversible damage to the kidneys, and for the infection to be eliminated through surgery and drainage, since conservative treatment using only antibiotics has demonstrated a worse prognosis (HUTCHISON; KAYSEN, 1988;KITSHOFF et al, 2011).…”

Renal abscesses in cats: six cases

“…They have only been described in isolated case reports, in association with pyelonephritis in cats and dogs, and with diabetes mellitus, polycystic disease and nephrolithiasis in dogs. 1–4 A case of post-traumatic RA with nephrocutaneous fistula has also been reported in a dog. 5 This report describes six cats diagnosed with RA and managed with a combination of medical and surgical treatments.…”
