RESUMO
A 3-week-old female dairy calf was presented because of severe weakness and diarrhea. Physical examination and ultrasound findings lead to a tentative diagnosis of intestinal obstruction, although serum biochemistry suggested a primary renal disorder. Reassessment of ultrasound images allowed diagnosis of hydronephrosis that had been misdiagnosed probably because of the clinician's biased Bayesian reasoning. Pyelonephritis without renal failure was diagnosed 2.5 months later. The calf was euthanized and the diagnoses were confirmed.
Une hydronéphrose rénale chez un veau laitier : quand le raisonnement Bayesien du clinicien rend le diagnostic plus difficile. Une génisse âgée de 3 semaines est présenté pour faiblesse générale et diarrhée. L'examen clinique et les images échographiques de l'abdomen sont compatibles avec une obstruction intestinale. Mais les résultats d'analyse biochimique montrent une anomalie rénale. Un examen échographique supplémentaire est compatible avec un diagnostic d'hydronéphrose. Le diagnostic d'hydronéphrose n'avait pas été fait à la première visite probablement suite au raisonnement Bayesien du clinicien. Le veau est revu 2,5 mois plus tard. L'échographie de l'abdomen, les analyses urinaire et sanguine montrent une pyélonéphrite sans insuffisance rénale. Le veau est euthanasié et l'autopsie montre l'hydronéphrose et pyélonéphrite bilatérale.(Traduit par les auteurs).

A female French bulldog was presented with an enlarged clitoris. Abdominal surgery revealed a normal uterus and gonads resembling testes. Histologically, the gonads contained seminiferous tubules. The karyotype was XX, and the SRY gene was not detected. A diagnosis of XX male, SRY negative disorder of sexual development was made.

A 5-year-old Holstein cow was examined for a unilateral enlarged ovary. A clinical diagnosis of ovarian tumor was established before a histological diagnosis of ovarian vascular hamartoma was made. Ovarian vascular hamartoma has not been reported previously in a live animal.
