Fig. 2. Anterior peritoneal reflection.

A. Schematic shows anterior peritoneal reflection (arrows) and its apex (^*), i.e., lowermost point of anterior peritoneal reflection.

B. Apex of anterior peritoneal reflection (^*) can be identified on sagittal MRI (left) in this male patient by following peritoneal line (arrowheads) over urinary bladder and seminal vesicle and by noting its termination in anterior rectal wall (^*). On axial view (right), peritoneal attachment makes “seagull”-like appearance.
