Figure 21b. An ectopic anal opening in the vaginal fornix of a septate uterus (same patient in Fig 12). The clinical examination showed absent anus in the perineum, with fecal matter coming from the vaginal opening. (a) Sagittal T2-weighted FSE image (4,000/98) obtained with the body coil shows poor detail in the uterine hemicavity and surrounding tissues. (b) An identical sequence used with the pelvic coil shows more detail at the suggested site of the ectopic anal opening (arrow) in the posterior vaginal fornix. Note the markedly distended colon (C).
