deamino-arginine-vasopressin and Leiomyosarcoma

Nephrogenic diabetes insipidus was diagnosed in a dog with an intestinal leiomyosarcoma. The diagnosis of nephrogenic diabetes insipidus was made on the basis of results of serum biochemical tests, urinalyses, and a water-deprivation test, along with a lack of response to exogenous administration of vasopressin following the water-deprivation test. The temporal association between resection of the intestinal mass and resolution of clinical signs of diabetes insipidus (i.e., polyuria and polydipsia) and between recurrence of clinical signs and detection of metastatic disease suggests that there may have been a causal relationship, and nephrogenic diabetes insipidus may have developed as a paraneoplastic syndrome in this dog.
