Pathology MCQ1

A 38-year-old woman has experienced severe abdominal pain over the past day. On examination she is hypotensive and in shock. Laboratory studies show elevated serum lipase. From the representative gross appearance of the mesentery shown in the figure, which of the following events has most
likely occurred?

A Acute pancreatitis
B Gangrenous cholecystitis
C Hepatitis B virus infection
D Small intestinal infarction
E Tuberculous lymphadenitis



Explanation:
The many focal, chalky white deposits in the mesentery, composed mainly of adipocytes, are areas of fat necrosis. The deposits result from the release of pancreatic enzymes such as lipases in a patient with acute pancreatitis. Gangrenous necrosis is mainly coagulative necrosis, but occurs over an extensive area of tissues. Viral hepatitis does not cause cell
necrosis in organs other than liver, and hepatocyte necrosis from viral infections occurs mainly by means of apoptosis. In-
testinal infarction is a form of coagulative necrosis. Infection with tuberculosis leads to caseous necrosis.So, the correct answer is option A(Acute pancreatitis).
