[|Human|] Hi, I have a hard ball in my stomach that I can feel my heartbeat in. I can move this ball around a little, but it is normally near my belly button. It is uncomfortable to push on but, not painful. My periods have not been regular but, no other symptoms. I am 30, never smoked and not high BP. I have lost 30 pounds in the past few months and wonder if this is just something I can feel now that I am thinner or if it is Abdominal Aortic Aneurysm? I have used Phentermine for weight loss in the past, no other prescriptions or health issues. Thank you!
[|AI|]  Hi. Thanks for your query. Gone through your history. You are feeling a hard ball-can move around-can feel heart beat in it- unconformable when pushed on and is near the belly button.IT is most probably NOT an aneurysm as you are suspecting, because you can move it around. (Aneurysm is fixed and can not be moved).IT is most probably a condition called a mesenteric cyst (mesentery is a membrane from which small intestines are supported and give supply of blood and return of the blood and lymph). The history you have provided is more near this diagnosis. I would advise undergoing an ultrasonography and color Doppler examination to confirm the diagnosis, see for the blood vessels. A CT scan may be needed to confirm the diagnosis and the nature and cause of this cyst. This can be cured by surgery.
