In short
In a baby, a bile duct cyst usually shows as yellow skin, pale stools and dark urine. In an older child or an adult, it shows as belly pain, fever or pancreatitis.
Few people have the textbook triad of pain, yellow eyes and a lump together. That is why the cyst is often found late.
A scan settles the question. A cyst found at any age should be planned and treated, because waiting adds risk.
This post explains the signs. For the full path of a bile duct cyst, from first report to treatment, see our choledochal cyst and Caroli treatment page.
In a baby, the first sign is often yellow skin that does not fade, with pale stools and dark urine.
Many newborns look yellow in the first week. That is common and usually settles. Yellow skin that lasts beyond two weeks, or that comes with chalk-pale stools, needs a doctor’s check. A bile duct cyst is one cause. Biliary atresia is another, and it cannot wait, so the two are sorted out together.
Some babies are found before birth. A routine pregnancy scan can show a fluid-filled sac near the liver, and the baby is then checked after delivery. Other babies have a firm lump in the upper right belly, or a swollen belly with poor feeding.
A cyst that blocks bile flow can strain the liver if it is left. This is why a baby with a suspected cyst is assessed early and not “watched for a year”.
An older child more often has belly pain, vomiting and repeated bouts of pancreatitis, with or without yellow eyes.
The textbook triad is belly pain, yellow eyes and a lump you can feel. In practice, only a small share of children show all three at once. Most show one or two, and the signs come and go.
A child may be treated again and again for “acidity”, worms or a stomach bug. The pain sits in the upper belly, often after meals. Fever with chills can appear when the stuck bile gets infected. Repeated pancreatitis in a child with no gallstones and no injury should raise the question of a cyst with an abnormal duct junction.
The first step is a simple ultrasound. A cyst next to the liver is then followed by an MRCP, which we describe in our post on bile duct cyst scans.
In an adult, a bile duct cyst usually shows as repeated upper belly pain, fever with yellow eyes, or pancreatitis that has no clear cause.
A cyst present since birth can stay quiet for decades. Then stones, sludge or infection form inside it, and the symptoms begin. Some adults are found by chance, when a scan is done for another reason.
The table below sets the usual picture side by side. The signs overlap, so use it as a guide and not as a test.
| Age group | Usual signs | Often mistaken for |
|---|---|---|
| Baby | Yellow skin beyond two weeks, pale stools, dark urine, a lump in the belly | Newborn jaundice, biliary atresia |
| Older child | Upper belly pain, vomiting, fever, repeated pancreatitis | Acidity, worms, stomach infection |
| Adult | Repeated pain, fever with yellow eyes, pancreatitis, stones in the duct | Gallstones, ulcer, idiopathic pancreatitis |
| Any age, no symptoms | Nothing, found on a scan done for another reason | A simple liver cyst |
An adult may also have a cyst that has been treated before with a stent or a bile duct drain. These steps relieve the block for a time, but they do not remove the cyst.
The signs look like common problems, and the first scan may be reported as gallstones or a widened duct without naming a cyst.
In adults, the pain and fever are put down to gallstones. The gallbladder is removed, yet the pain returns, because the cyst is still there. In others, repeated pancreatitis is labelled “idiopathic”, which means no cause was found.
Reports can also use words that hide the answer. “Dilated common bile duct” may be a cyst, or it may be a stone further down. Only the full pictures show the difference.
Three clues should make a doctor think of a cyst:
If you have had one of these, bring the actual images, not only the printed reports.
Fever with chills and yellow eyes, severe belly pain, or repeated vomiting need a doctor the same day.
These signs can mean the bile is infected, which is called cholangitis, or that the pancreas is inflamed. Both can turn serious fast. In a baby, pale stools with yellow skin beyond two weeks should be seen within a day or two.
Mild, steady symptoms are still worth a scan. Waiting for a “bad attack” only gives the cyst more time to cause harm.
The plan is to treat the cyst, usually by taking it out and rebuilding the bile flow, once the scan has shown its type.
The type is read from the scan, as described in our post on bile duct cyst types. The operation, cyst removal with a new bile duct join, is covered in our post on cyst removal and the new bile duct join.
Why not wait? A cyst left in place can cause attacks of infection and pancreatitis. Over the years, the lining can also change, and the chance of cancer rises with age. That is why we plan treatment even when symptoms are mild, as explained in our post on cancer risk and lifelong follow-up.
A baby with a suspected cyst and a very ill adult with infection may first need the infection controlled. The surgery is then planned for a safe time.
Yellow skin that lasts beyond two weeks, pale stools and dark urine. Some babies also have a lump in the upper right belly.
Yes. Some people have no symptoms for years. The cyst is then found by chance on a scan done for another reason.
No. Only a few have all three together. Most have one or two signs, and they come and go.
A bile duct cyst can stay behind after the gallbladder is removed. It can keep causing pain, fever or pancreatitis, so it needs a scan.
Yes. When the bile duct and the pancreas duct join abnormally, pancreatic juice can flow back and cause repeated pancreatitis.
No. Both cause yellow skin and pale stools in a baby, but they are different conditions. A scan and tests tell them apart.
Usually yes. A cyst left in place can cause infection and pancreatitis, and the chance of cancer rises with age.
