Hypercalcemia in a bag: A challenging case

An 18-month-old, spayed female, mixed-breed dog was referred for investigat ion of persistent hypercalcemia. After extensive diagnostic evaluation, a t entative diagnosis of occult lymphosarcoma (LSA) was made and the dog was e uthanized. At necropsy, infection with Heterobilharzia americana was diagno sed. In endemic areas, schistosomiasis should be included in the differenti al diagnosis of hypercalcemia, and a fecal examination should be performed in every dog with a hypercalcemia of unknown origin.
