Which of the following is false about mucocele of gallbladder?
**Core Concept**
Mucocele of the gallbladder is a condition characterized by the distension of the gallbladder with mucus, often resulting from the obstruction of the cystic duct or the presence of a mucosal defect. This leads to the accumulation of mucus within the gallbladder, which can cause significant discomfort and potentially life-threatening complications if left untreated.
**Why the Correct Answer is Right**
The formation of a mucocele is typically due to the obstruction of the cystic duct, which prevents the normal emptying of the gallbladder. This obstruction can be caused by gallstones, tumors, or other lesions that impede the flow of bile and mucus. As a result, the gallbladder becomes distended with mucus, which can lead to symptoms such as abdominal pain, nausea, and vomiting.
**Why Each Wrong Option is Incorrect**
**Option A:** This statement is true, as mucocele of the gallbladder can indeed cause abdominal pain and discomfort due to the distension of the gallbladder.
**Option B:** This statement is true, as the obstruction of the cystic duct is a common cause of mucocele formation.
**Option C:** This statement is false, as mucocele of the gallbladder is not typically associated with an increased risk of gallbladder cancer. While there may be an increased risk of cancer in cases where the mucocele is caused by a mucosal defect or a tumor, this is not a universal characteristic of mucocele of the gallbladder.
**Clinical Pearl / High-Yield Fact**
It's essential to note that mucocele of the gallbladder can be a challenging diagnosis, as the symptoms may be non-specific and can be similar to those of other gallbladder disorders. A high index of suspicion and imaging studies, such as ultrasound or CT scans, are often necessary to confirm the diagnosis.
**Correct Answer: C.**
