Question: 2 year old with lump under sternum

 greengurl61 - Thu Aug 05, 2010 6:12 am

My 2 year old son has 1 maybe 2 lumps under his xyphoid process and toward the left side under the ribs immediately attached there. What could this be? Lipoma? But it isn't on the surface it seems more internal.
Thanks for any help you can give.

User avatar Hi,
There could be several causes for a lump close to the xiphisternum in this age group.
- benign soft tissue tumors(lipomas, neurofibromas)
- rectus sheath hematomas.

One of the more common causes of abdominal wall trauma in children is lap belt injury. In addition to intraabdominal manifestations such as bowel injury, lap belt injuries can result in contusion or hematoma of the anterior abdominal wall. If there is injury to the structures within the rectus sheath (rectus abdominis muscle, the superior and inferior epigastric vessels), a rectus sheath hematoma results. It can be occur in any part of the rectus sheath(more common below the arcuate line). Occasionally, it occurs as a feature of child abuse.

In your child's case, as there is no history of pain, tenderness or redness(to suggest a rectus sheath hematoma), a lipoma or a neurofibroma are the more likely diagnoses to be entertained.You must show your son to his pediatrician who will be able to arrive at a more definitive diagnosis after examining your son.
Best wishes!
