Choledochal Cyst – Board-Style Questions

What this deck covers

choledochal cyst in 18 board-style clinical cases with worked explanations. Each case gives you a clinical vignette, four options, the correct answer, and an explanation of why each of the other three is wrong, with the guideline or textbook it follows named on the answer.

Board-style teaching questions for paediatricians and trainees preparing for paediatric board, MRCPCH and licensing examinations. Written from published guidelines and standard paediatric textbooks, with the source named on every answer.

The 18 cases, in order

1. Pain that keeps coming back
2. A cyst on the fetal scan
3. The commonest type
4. Only inside the liver
5. Where the ducts meet
6. Who gets it
7. Cyst or duplication
8. Inside the duodenum
9. Sudden swelling in a baby
10. Joining it back up
11. Seen on the fetal scan, well now
12. Fever years after the operation
13. An old operation
14. Discharged from clinic
15. What the bile showed
16. Years of waiting
17. Too unwell for the big operation
18. Found at 20 weeks

Diagnoses and management options tested

Across the 18 cases you are asked to choose between options such as: Gallstones from haemolysis, Cystic biliary atresia, Type II, a diverticulum of the duct, Polycystic liver from ADPKD, A long common pancreaticobiliary channel, Boys of Northern European descent, Tracer taken up by the thyroid gland only, Long-term antibiotic prophylaxis, Perforation with bile peritonitis, The cyst joined directly to the duodenum, Only if symptoms develop in adult life, Viral hepatitis unrelated to surgery, Cholangiocarcinoma arising from the lining, Stop all review, since excision cures the condition.

Clinical pearls from this deck

• Recurrent pain plus a dilated common duct: choledochal.
• Small cyst and pale stools: exclude cystic atresia.
• Type I, extrahepatic, is the commonest.
• Intrahepatic saccules only: Caroli disease.
• Choledochal cysts: look for a long common channel.
• Choledochal cysts: more girls, more East Asians.

Work through the deck once for recognition, then again a week later to test yourself — each question gives the answer and explains why every other option fails.
