Summary Six Bull Terrier puppies of 2 months had ultrasound exam for detection of any liver, kidney and heart anomalies before sale. All had hyperechogenic septa, in the gall bladder, giving it a honeycomb appearance. The puppy, whose septa were the biggest developed cholecystitis and a gall bladder abscess with two gall stones at the age of 5. Septation of the gall bladder is a very rare malformation in humans. One author formulated the hypothesis of a vacuolation anomaly of the gall bladder which occurred during embryo development. Among the 44 human cases published, 12 concerned asymptomatic patients. Clinical manifestations are most frequently biliary symptoms: vomiting and nausea combined with a pain in the upper quadrant of the abdomen. The prevalence of the anomaly among the population is unknown. This case is, as far as we know, the first description of ultrasound modifications and clinical development of multi-septate gall bladder in dog.

Summary A sterilised 4-year-old cat, living in contact with hunting dogs, was presented following several days of vomiting and diarrhea. In a state of shock, she was hyperesthetic and handling was painful. She had marked inflammatory lesions on her pinnas, abdominal skin and foot digits. Proteinuria was elevated without significant sediment. Blood analysis revealed pre-renal azotemia, and hyperglobulinemia. An abdominal ultrasound examination showed nephromegaly and an echomodified pancreas (snap fPL test negative). A search for anti-nuclear factors was negative. PCR blood analyses were slightly positive for Leptospira spp. and negative for Ehrlichia spp. and Anaplasma spp. A treatment based on cefovecin and methylprednisolone (5 days) then 14 days afterwards, doxycycline (4 weeks) was prescribed. The cat recovered completely. A double serology test, carried out at 5 weeks’ interval, showed a significant seroconversion for Leptospira serogroup Sejroe serovar Saxkoebing (snap FeLV/FIV combo test negative). This case shows that cats can develop clinical leptospirosis without an apparent cause of immunosuppression, with symptoms partly comparable to those of the canine subacute form, and particularities. The Sejroe serogroup will therefore have to be included in the future in serological testing if there is a clinical suspicion of leptospirosis in cats.

We report the diagnosis and follow-up of a septal myocardial abscess in a seven-year-old Anglo-French hound suffering from both renal failure and urinary infection. Serial echocardiography showed the abscess enlarging and progressing into a fistula between the left ventricular outflow tract and the right ventricle. The dog died despite early wide-spectrum intravenous antibiotic therapy. Post-mortem examination confirmed the diagnosis. Bacterial and fungal myocardial abscesses have been described in immunodeficient human beings. To our knowledge, fistulae have rarely been described in dog hearts and only as a consequence of previous valvular endocarditis. In our case, the sigmoid cusps were not involved, so this is the first description of a septal myocardial abscess in a dog.
