The radiologist reported circumferential wall thickening of the rectum with an air-fluid level (Figure 1). Comparison with the retroperitoneal ultrasound suggested that the presumed fluid-filled rectum was actually the enlarged prostatic utricle located posterior to the bladder (Figures 1 and 2).
Our patient's MRI of the abdomen and pelvis (sagittal and axial) more clearly demonstrates that the fluid-filled structure located in the midline and posterior to the bladder (Bl) is actually an enlarged prostatic utricle (**) filled with debris.
