A case of splenic torsion with progressive anemia and thrombocytopenia.

A 4-year-old male, castrated Saint Bernard was evaluated for acute onset of lethargy and collapse. Moderately severe anemia and splenomegaly were noted. Immune mediated hemolytic anemia was initially suspected. Abdominal ultrasound demonstrated an absence of splenic blood flow. Splenic torsion was confirmed on exploratory laparotomy and a splenectomy was performed.
