Fig. 1A.56-year-old man with acute alcoholic pancreatitis. Early
unenhanced contiguous axial CT scans show normal pancreas with haziness and
increased attenuation in peripancreatic fat, denoting CT grade C.
Fig. 1B.56-year-old man with acute alcoholic pancreatitis. Early
unenhanced contiguous axial CT scans show normal pancreas with haziness and
increased attenuation in peripancreatic fat, denoting CT grade C.
Fig. 2A.53-year-old man with acute alcoholic pancreatitis. Early
unenhanced axial CT scan shows enlargement of pancreatic body and fluid
collections in anterior and posterior left pararenal spaces (arrows),
denoting CT grade E.
Fig. 1C.56-year-old man with acute alcoholic pancreatitis. After IV
contrast material administration, CT scans obtained at same levels as A
and B show homogeneous enhancement of pancreas, denoting no
necrosis.
Fig. 1D.56-year-old man with acute alcoholic pancreatitis. After IV
contrast material administration, CT scans obtained at same levels as A
and B show homogeneous enhancement of pancreas, denoting no
necrosis.
Fig. 2B.53-year-old man with acute alcoholic pancreatitis. CT scan
after administration of IV contrast material shows normally enhancing proximal
body of pancreas but no enhancement of remaining pancreatic body and tail
(> 50% necrosis).
Fig. 2C.53-year-old man with acute alcoholic pancreatitis. Follow-up
contrast-enhanced CT scan 12 days later shows large fluid collection with
airfluid level (arrows) anterior to partially necrotic
pancreatic body and tail. Abscess caused by Escherichia coli was
surgically drained. Asterisk indicates stomach.
Fig. 3A.47-year-old woman with ERCP-induced acute pancreatitis. Early
unenhanced axial CT scan shows slightly enlarged pancreatic head and body with
poorly defined contours. On more caudal scans (not shown), fluid collections
were observed in anterior right and left pararenal spaces, indicating CT grade
E.
Fig. 3B.47-year-old woman with ERCP-induced acute pancreatitis. After
administration of contrast material, CT scan shows lack of enhancement of
pancreatic head and body (> 50% necrosis) and normal enhancement of
pancreatic tail.
Fig. 3C.47-year-old woman with ERCP-induced acute pancreatitis.
Follow-up contrast-enhanced CT scan 6 weeks later shows development of
encapsulated pancreatic pseudocyst in head and body of pancreas. Surgical
drainage was performed.
