How are choledochal cysts diagnosed?
Choledochal cysts can be diagnosed prenatally on an ultrasound.
After your baby is born, you or your child's doctor may notice a right upper quadrant mass, with or without jaundice.
Your child will likely undergo a combination of the following tests to verify the diagnosis:
Computerized tomography scan (CT or CAT scan) — A CT scan shows detailed images of any part of your child’s biliary system.
- CT scans are more detailed than general x-rays.
- Cholangiography — This is a radiographic visualization of your child’s bile ducts after ingestion or injection of a substance that illuminates the ducts.
