Cyst
A cyst is a fluid-filled sac that can occur in many parts of the body.
When to get help quickly: A cyst needs quicker review if there is severe pain, fever, rapid swelling, vomiting, or signs that it may have burst, twisted, become infected, or blocked an organ.
Common symptoms
Many cysts cause no symptoms. When they do, symptoms may include a lump, pain, swelling, pressure, or symptoms caused by the organ or body part where the cyst is located.
When imaging helps
Imaging helps show whether a cyst looks simple and harmless or more complex, infected, bleeding, or suspicious, and it helps doctors see its exact size and location.
What radiology does
Ultrasound, CT, and MRI help determine whether the cyst looks simple, complex, infected, or suspicious.
What usually happens next
Many cysts are harmless and only observed, while others may need drainage, follow-up imaging, or surgery.
