- Loss of serosal detail in the cranial abdomen (minor finding)
- Generalized splenomegaly/mass effect, with caudal displacement of abdominal viscera
- Cranial abdominal mass effect, likely originating from the spleen
- Loss of serosal detail consistent with effusion
- Differentials: Splenic enlargement secondary to splenic torsion (correct answer), other causes of generalized splenomegaly
- Ultrasound to look for splenic involvement, examine spleen for decreased perfusion
- All candidates identified a cranial abdominal mass effect, although some felt that abdominal detail was normal, and others attributed loss of detail to a thin body condition. Many candidates attributed the mass effect to either the stomach (outflow obstruction) or to the pancreas (pancreatitis/abscess).
- Highest point totals were given to candidates who listed splenic torsion as first in the differential list, although points were also awarded for a diagnosis of generalized splenomegaly with other differentials.
