Visceral scalloping in pancreatic ascites: An uncommon manifestation of pancreatitis

Abstract
Scalloping of visceral organs like liver and spleen can cause certain peritoneal diseases. It has usually been described with pseudomyxoma peritonei and peritoneal carcinomatosis. Occasionally, it has also been described with certain benign conditions like peritoneal tuberculosis. We describe visceral scalloping in setting of pancreatic diseases. We believe that pancreatic fluid collections exert significant pressure on the visceral organs to result in scalloping of the visceral surfaces.
A 16-year-old male diagnosed as traumatic pancreatic ascites had ascitic fluid amylase levels of 60,000 U/L. Magnetic resonance imaging revealed ascites and scalloping of the liver surface (Figure 1A). Another 31-year-old male, chronic alcoholic, presented with alcohol-related acute pancreatitis. Computed tomography showed acute necrotic collection and scalloping of the liver margin (Figure 1B). Another, 54-year-old male presented with grade 4 traumatic pancreatitis. CECT revealed the presence of scalloped liver margin (Figure 1C). All these three patients were managed with percutaneous drains and one received pancreatic stenting with subsequent improvement.
Depicting scalloping of the liver in pancreatitis.
The radiological finding of visceral scalloping, characteristic for pseudomyxoma peritonei and peritoneal carcinomatosis, has been occasionally reported with benign conditions [1, 2]. To the best of our literature search, it has never been described so far in the setting of acute or chronic pancreatitis. We postulate that indentation/extrinsic compression by pancreatic fluid collections can result in scalloping of viscera.
