Mushroom cap sign (endometriosis)
Updates to Article Attributes
Body
was changed:
Mushroom cap sign is one of the important signs of deep rectosigmoid endometriosis seen on T2 weighted MRI sequence MRI sequence. It indicates the submucosal involvement in rectosigmoid region.
Radiographic appearance
MRI
Hypertrophic muscularis propria appears as heterogeneous low signal intensity surrounded by high signal intensity of mucosa and submucosa. This gives characteristic appearance of mushroom cap.
