Not true regarding choledochal cyst –
**Core Concept**
Choledochal cysts are congenital anomalies of the bile ducts, characterized by dilatation of the intrahepatic or extrahepatic bile ducts. They may be classified into different types based on their location and morphology.
**Why the Correct Answer is Right**
The correct answer is related to the pathophysiology and clinical presentation of choledochal cysts. Choledochal cysts are associated with an increased risk of malignancy, particularly in the distal common bile duct. The dilated bile ducts are prone to stone formation, infection, and cholangitis, leading to symptoms such as abdominal pain, jaundice, and fever.
**Why Each Wrong Option is Incorrect**
**Option A:** Choledochal cysts are always asymptomatic in childhood. This statement is incorrect because choledochal cysts can present with symptoms in childhood, such as abdominal pain, jaundice, and fever.
**Option B:** Choledochal cysts are always unilateral. This statement is incorrect because choledochal cysts can be bilateral, particularly in Caroli's disease.
**Option C:** Choledochal cysts are always associated with anomalous pancreaticobiliary junction. This statement is incorrect because while anomalous pancreaticobiliary junction is a risk factor for choledochal cysts, not all choledochal cysts are associated with this anomaly.
**Clinical Pearl / High-Yield Fact**
It is essential to remember that choledochal cysts are a risk factor for malignancy, and surgical excision is usually recommended to prevent long-term complications.
