Ultrasound: The spleen revealed a complex mixed echogenic cystic and hyperechoic parenchymal mass measuring approximately 7+ cm. The mass appeared fairly vascular and occupied much of the mid cranial abdomen. The mass appeared to be deriving from the caudate process of the liver; however, it occupied areas of the pancreas as well. The gastrointestinal tract was deviated by the mass. Free fluid noted in the abdomen, likely owing to mass hemorrhage.

Radiographs: Radiographs revealed undifferentiated cranial abdominal mass and ascites.

Cytology: Submitted are several videos and one image collected from the abdominal mass in the patient. The cellularity is rather uniform throughout all of the videos and the one image consists of necrotic cells. There is necrotic debris interspersed with prominent neutrophils and very few other inflammatory cells. Many of the neutrophils are demonstrating toxicity or degeneration. There are scattered bacteria in the background. In the more hemorrhagic collection, the cellularity is mixed but it is inflammatory. Neutrophils are prominent in those videos as well. The cellularity in all of these videos supports a rather severe chronic inflammatory process. There are excellent collections of cells that support an abscess. There are even scattered structures that suggest coccobacillus bacteria. There is no suggestion of malignant cellularity in the collection.
