Figure 18: (a) Normal pancreas (left) and acute pancreatitis with peripancreatic fluid (right). (b) Acute pancreatitis with necrosis and pseudocyst formation. When inflamed, pancreas enlarges in size and is bulky with peripancreatic fluid, indicative of acute pancreatitis. Severe pancreatitis can present with necrosis, wherein there is a loss of normal appearance of pancreas, intrapancreatic hypoechoic necrotic areas. Thick-walled collections usually represent a pseudocyst or a walled-off necrosis. Internal contents and debris can help in differentiating the two. The presence of foci of air (hyperechoic foci with comet-tail artifact) is suggestive of superadded infection
