Calcitriol induced hypercalcemia in a hunting dog with a disseminated Paecilomyces variotii infection

摘要

A 5-year old hunting dog was presented with reduced appetite, weight loss and polyuria/polydipsia. Hematology and clinical chemistry revealed anemia, leukocytosis, increased liver enzymes, hypoalbuminemia and hypercalcemia. The cytological, pathohistological and microbiological examination identified a disseminated infection with the saprophytic mould fungus Paecilomyces variotii in the biopsies of the spleen and a lymph node. Determination of vitamin D metabolites confirmed a calcitriol induced hypercalcemia.
