Which condition is indicated by a palpable gallbladder in a patient with jaundice and weight loss?

A palpable gallbladder in the context of jaundice and weight loss is indicative of a pancreatic tumor, particularly when it is associated with Courvoisier's sign. This sign arises when a malignant obstruction of the bile duct occurs, often due to a tumor in the head of the pancreas, leading to an enlarged gallbladder. The bile duct obstruction prevents bile from draining into the intestine, resulting in the accumulation of bile and subsequent jaundice.

In this scenario, along with the weight loss, the presence of a palpable gallbladder suggests that the underlying cause is more than just a gallbladder pathology like cholecystitis or gallstones. Instead, it points toward a more sophisticated pathophysiological process, such as malignancy, where the obstructive process is due to an external mass effect rather than an issue solely within the gallbladder itself.

Cholecystitis and cholelithiasis would typically present with right upper quadrant pain, nausea, and other gastrointestinal symptoms rather than a palpable gallbladder in the context of significant weight loss and jaundice. Hemorrhagic pancreatitis, while it can be debilitating and lead to a variety of complications, typically does not result in a palpable gallbladder
