This paper presents an imaging report-style description of the “mushroom cap” sign in deep rectosigmoid endometriosis, focusing on the MRI appearance of endometriotic lesions in that anatomic location. It discusses the sign as a specific radiologic feature associated with deep pelvic endometriosis in the rectosigmoid compartment, without providing new patient data. A stated limitation is that the manuscript does not include any human participant or animal study. This paper is centrally about endometriosis — it specifically highlights the “mushroom cap” sign in deep rectosigmoid endometriosis.
