            Figure 24.14  A 10-year-old Russian Blue presented for anorexia and icterus. Lateral (a) and ventrodorsal (b) radiographic images
            show caudal displacement of the gastric axis due to hepatic enlargement. (c) On abdominal ultrasound, the pancreas is enlarged and
            contains multiple varible sized anechoic noudles. After this patient died, chronic multifocal mild to moderate pancreatic fibrosis along
            with chronic cholecystitis was found on the histopathologic examination.

                                                              Multiple pseudocysts were present in one cat. Aspiration of
