From: Acute abdominal pain in women of reproductive age: keys to suggest a complication of endometriosis
39-year-old female presenting with acute clinical intestinal obstruction. Axial enhanced CT (a, b) shows a large and small bowel distension (arrows), as a consequence of obstruction by a recto-sigmoid mass (white dotted circle, (b)). Features of long-standing left urinary obstruction (black plain circle) may be suggestive of deep endometriosis (a). T2W MRI (c, d) shows a stellar retractile hypoT2 mass of the Douglas pouch with colic asymmetric muscular thickening (white dotted circle) consistent with deep endometriosis of the torus (arrowhead) extending transmurally to the recto-sigmoid with stenosis and left ureter involvement
