What causes an abdominal mass?
Abdominal masses can be caused by a wide variety of conditions and diseases. An accumulation of new tissue (a tumor), fluid, a bowel obstruction, bacterial infection, fungal infection, parasitic infection, expansion of an organ, or entrapment of an organ can all cause abdominal masses.
Because the causes, treatments, and complications vary so widely, it is very important to have any abdominal mass examined promptly by a physician. Your physician will be able to tell a great deal based on the location of your abdominal mass, as well as the texture, mobility, size, shape, and firmness of the mass. In many cases, imaging, such as a CAT scan or an MRI, may be required.
Common causes of an abdominal mass
Abdominal mass may be caused by a variety of conditions including:
- Abdominal adhesions or scars, especially with past abdominal surgery
- Cancer of the colon, liver, pancreas, reproductive organs, bladder, kidneys, or other organs
- Crohn’s disease (inflammatory bowel disease that can affect any part of the intestine)
- Cysts anywhere in the abdomen
- Enlarged lymph nodes due to inflammation or cancer
- Inflammation or blockage of the gallbladder
- Intestinal obstruction
Rare causes of an abdominal mass
A wide variety of rare causes of abdominal mass exist, including many different types of cancer and rare genetic disorders resulting in cysts or other abdominal masses.
Serious or life-threatening causes of an abdominal mass
In some cases, an abdominal mass may be a symptom of a serious or life-threatening condition that should be immediately evaluated in an emergency setting. These include an abdominal aortic aneurysm.

To diagnose your condition, your doctor or licensed health care practitioner will ask you several questions related to your abdominal mass including:

What are the potential complications of an abdominal mass?
An abdominal mass can be a mild condition that is highly treatable or a serious and life-threatening emergency. Because the causes of abdominal mass vary so widely, complications and prognoses also vary widely.

Once the underlying cause is diagnosed, it is important for you to follow the treatment plan that you and your health care professional design specifically for you to reduce the risk of potential complications including:
- Gastrointestinal perforation and sepsis
- Infertility due to permanent damage to the reproductive tract
- Permanent kidney damage
- Permanent liver damage
