The duodenum is part of the small intestine. Sometimes if there is a weak spot in the wall of the intestine, a small bulge (diverticulum) can form. Diverticula usually do not cause symptoms.
There is a moderate amount of stool present in the large intestine (colon). Constipation is a common condition that makes it hard to have bowel movements due to stools being too hard, too small, infrequent or difficult to pass. Chronic constipation may be caused by poor diet, a side effect of medication use, and diseases of the digestive tract (e.g. IBS, diverticular disease). Treatment for constipation includes eating foods high in fiber, increasing water intake, regular exercise, creating a regular schedule for bowel movements and, if needed, using laxatives or enemas.
The cecum is the connection between the small and large intestines. The cecum is normally connected to the abdomen; sometimes during embryonic development, no connection forms and the cecum can move from its normal position in the right lower part of the abdomen. This condition is called mobile cecum and is usually asymptomatic (does not cause symptoms). Rarely, it can cause constipation, abdominal pain and weight loss.
There is a mass (growth) in the pelvis based on your MRI images. This could be harmless or something more meaningful (e.g. a cancerous growth). To determine exactly what this mass is, further imaging is needed.
Cervical fibroids (also called cervical myomas, leiomyomas of the cervix) are abnormal growths of muscle tissue in the cervix. They are thought to be caused by an excess of estrogen, a hormone involved in cellular growth, and may also develop due to an imbalance between estrogen and progesterone. Cervical fibroids are benign (non-cancerous) and are usually asymptomatic (do not cause symptoms), but sometimes can be the cause of abnormal vaginal bleeding, painful sexual intercourse, and abdominal/pelvic pain.
The endocervical cavity (canal) is the space connecting the vagina with the uterus. Sometimes it can be more expanded or wider than usual. It is unclear what causes this finding, but could be associated with history of vaginal birth delivery.
