Re: Gastro to Intestinal to..Back??
That makes sense that you thought you were having an attack of appendicitis. That is how the pain of mesenteric lymphandenopathy is described. It is an inflammation of the lymph nodes in the membrane that attaches the intestine to the wall of the abdomen. It is caused by an intestinal infection and can be very painful. And, there is a thickening of the ilium, which is the final end of the small intestine...it is at about the same level as the lowest lumbar discs.
I assume that the back was imaged as a part of the abdominal scans. So this is considered an incidental finding...and is only mentioned in passing. It has nothing to do with your mesenteric lymphandenopathy.
[B]a congenital nonunion of posterior arch of S1, and a mild symmetric disc bulge at L5 - S1.[/B] A congenital nonunion of the posterior arch of the Sacral 1 vertebra...just means that the bone is slightly deformed and has been this way since birth. I don't believe this could be responsible for any back problems. At the disc located between the last lumbar and first sacral vertebrae, there is a small disc bulge that is located in the middle (neither on left or right side). Most people have a disc that is bulging...it is just a sign of living, wear and tear, and is not something one notices unless it becomes larger and irritates or pushes into a spinal nerve. As I mentioned, these are considered incidental findings and most likely are causing you no pain or "issues" whatsoever.
