A 50-year-old chronic alcoholic and smoker presents with intermittent episodes of epigastric pain, nausea and vomiting, along with features of malabsorption since the past 6 months. He has lost 12 kg over the last year and was hospitalized for 3 days, 3 years ago with acute abdominal pain. Serum amylase and lipase are only mildly elevated. A CT-scan of the abdomen was done along with MRCP. What is the possible diagnosis:- CECT ABDOMEN MRCP

**Core Concept**
The patient's symptoms and history suggest chronic pancreatitis, which is a progressive inflammatory condition of the pancreas leading to fibrosis and irreversible damage to the gland. Chronic pancreatitis is often associated with a history of heavy alcohol consumption and smoking, which can cause recurrent episodes of pancreatitis.

**Why the Correct Answer is Right**
The CT-scan and MRCP findings, along with the patient's symptoms and history, are consistent with chronic pancreatitis. Chronic pancreatitis can cause malabsorption due to the destruction of pancreatic enzymes, leading to weight loss and abdominal pain. The mildly elevated serum amylase and lipase levels are consistent with chronic pancreatitis, as the levels may not be significantly elevated in this condition. The CT-scan may show calcifications in the pancreas, and the MRCP may show a dilated pancreatic duct.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the patient's symptoms and history are not consistent with pancreatic cancer, which typically presents with jaundice and weight loss in the absence of abdominal pain.

**Option B:** This option is incorrect because the patient's CT-scan and MRCP findings are not consistent with acute pancreatitis, which typically presents with severe abdominal pain and elevated serum amylase and lipase levels.

**Option C:** This option is incorrect because the patient's symptoms and history are not consistent with duodenal ulcer disease, which typically presents with epigastric pain and nausea, but not malabsorption.

**Option D:** This option is incorrect because the patient's symptoms and history are not consistent with gastric cancer, which typically presents with weight loss, abdominal pain, and jaundice in the absence of malabsorption.

**Clinical Pearl / High-Yield Fact**
In patients with chronic pancreatitis, the presence of calcifications on CT-scan and a dilated pancreatic duct on MRCP are highly suggestive of this diagnosis. Additionally, the patient's history of heavy alcohol consumption and smoking is a significant risk factor for chronic pancreatitis.

**Correct Answer:** C.

✓ Correct Answer: B. Chronic pancreatitis
