What Could Cause a Lump in the Middle of the Abdomen?

There are several conditions that can result in a lump in the middle of the abdomen. One common cause is a hernia, where part of the intestine or other tissue pushes through a weakness in the abdominal wall. A specific type called a Spigelian hernia occurs along the side of the rectus abdominis muscle and can appear as a lump in this region. Other possible causes may include masses, such as tumors, though there are other benign causes as well, such as lipomas or cysts, which are typically soft and non-tender. Although less common, if the lump is tender and pulsatile (throbbing with your heartbeat), it might indicate a vascular condition such as an abdominal aortic aneurysm, Because each of these causes has different implications, it is important to have a healthcare provider evaluate a new or changing abdominal lump to determine the correct diagnosis and appropriate management.
