On ultrasound, bowel endometriosis typically looks like a hypoechoic (darker) mass, nodule, or thickening within or attached to the bowel wall, often with irregular edges, sometimes forming a characteristic C-shape or spiculated appearance, and involving the muscular layer, potentially with surrounding adhesions causing tethering. It appears as a solid, irregular lesion, sometimes with bright spots (echogenic foci), and can be difficult to see if very small or superficial, though specialized techniques can help.
The ultrasound can also show signs of endometriosis (like scarring) or show an endometrioma or bowel mass. Your healthcare provider can help you understand your results and, most importantly, what these results mean for your care.
Nodules of endometriosis tend to appear sonographically as solid, hypoechoic, irregular masses. They may contain echogenic foci or small cystic spaces and often show little or no blood flow on color Doppler. lesions can vary in size from a few millimeters to several centimeters.
It was also our clinical impression that many patients with endometriosis reported easy bruising and mucosal bleeding symptoms even in the absence of any trauma.
Bowel Endometriosis Causes
With this condition, doctors usually find a small mass of tissue (lesion) on your bowel wall. More rarely, a lesion can work its way into the muscular layer as well. These lesions grow slowly. They may get bigger, but it's also not uncommon for them to shrink.
Symptoms of endometriosis of the bowel
It is estimated that up to 15% of all women of reproductive age have endometriosis. About one-third of infertile women suffer from endometriosis[3]. Endometriosis affects the bowel in 3%-37% of all cases[4], and in 90% of these cases the rectum or sigmoid colon are also involved[5,6].
pain when you poo or pee. pain during or after sex. extreme tiredness (fatigue) pain or bleeding in other areas, such as in the chest, which may cause shortness of breath and coughing up blood.
Omental endometriosis is a rare entity, with only a few cases reported [7], [8]. Although rare, there have been reports of large endometriomas causing mass effect within the abdominal cavity, with the largest case report describing a 64 kg endometrioma [9].
Superficial Endometriosis
Appearance: Sometimes cells are active, red spots that bleed and look a lot like the inside of the womb, but are surrounded by inflammation. Cysts might be brown or look like tiny black spots, showing they have bled before. Finally, other patches are whitish, probably with scarring.
This wastes time in delaying what is best treated early than late.
Usually the laparoscopic diagnosis derives from the identification of the typical black or dark bluish or deep red spots on the peritoneal surface. One can easily miss the presence of endometriosis when a less marked discoloration is present.
From our experience, the most useful imaging techniques are transvaginal ultrasound (TVUS) and transrectal ultrasound (TRUS), combined with double contrast barium enema (DCBE).
The ultrasound aspect of deep endometriosis is a hypoechoic thickening or the presence of a nodule or mass with regular or irregular contours located in the posterior cervical region or pouch of Douglas(12).
Careful attention to the bowel when performing a pelvic US may allow the sonographer to diagnose GI pelvic diseases such as appendicitis, diverticulitis, colitis, bowel obstruction, mesenteric adenitis, epiploic appendagitis, Crohn disease, and even GI malignancy.
"Endo belly" is the nickname people use for the dramatic swelling that often comes with endometriosis. Your abdomen (belly) may stretch from under your ribs down to your pelvis, leaving your whole midsection tight and painful. Some people say it makes them look six months pregnant.
This is because endometriosis that spreads to the intestines will often present many of the same symptoms as the other diseases, such as painful bowel movements, constipation, nausea, and vomiting.
Endometriosis flare-up
These flare-ups can occur due to hormonal changes, particularly during menstruation. Stress, diet, or lack of rest can also trigger a flare-up. During these episodes, endometrial tissue outside the uterus becomes inflamed, leading to discomfort.

The feeling of needing to pass bowel movements more frequently or urgently than usual. The feeling of not being able to empty your bowel ...
Endometriosis is a chronic condition where tissue similar to the uterine lining grows outside the uterus, causing pain or silent symptoms like bloating, fatigue, and digestive or urinary issues. Chronic bloating. Lower back pain. Fatigue that lingers even after rest.
Extra pelvic endometriosis is an uncommon entity and sites include the bowel, appendix, pleura and lung, abdominal wall, particularly the umbilicus and around surgical scars. Endometriosis in the groin is rare.
Bowel endometriosis is typically classified as Stage 4 (Severe Endometriosis) because it involves deep tissue infiltration. Doctors categorize this form as “Deep Infiltrating Endometriosis” (DIE) since the lesions penetrate more than 5mm beneath the tissue surface.
Medications range from pain relief drugs (such as paracetamol and anti-inflammatories), to hormonal treatments that suppress ovulation and periods. Surgery can be used to remove or destroy the endometriosis. The most common surgery approach is laparoscopy (key-hole surgery).
In some instances of bowel endometriosis, women remain asymptomatic, with 5% of the larger lesions remaining symptom free and in whom surgical resection is probably not indicated. Symptoms may improve with medical treatment; however, deep infiltrating lesions are less likely to resolve.
