Thrombosis induced urinary bladder rupture in a canine patient with controlled primary immune‐mediated thrombocytopenia

Abstract

AbstractA 7‐year‐old, female, spayed springer spaniel presented due to acute stranguria and absence of reported urination by the owner. Two weeks earlier, it had been diagnosed with primary immune‐mediated thrombocytopenia for which it was receiving prednisolone. Imaging revealed the presence of abdominal effusion and severe urinary bladder changes, compatible with cystitis and urinary bladder wall haemorrhage. A urinary bladder wall rupture at its cranioventral pole was confirmed with contrast study. Cytology of the abdominal fluid concluded septic uroabdomen. Surgical management was elected. A large urinary bladder tear was present along with multi‐focal areas of suspected necrosis. The splenic appearance was also considered abnormal. At that stage, euthanasia was elected. Histopathology revealed features suggestive of thrombosis/infarcts in the urinary bladder and spleen.
