Impressions on floor of female bladder: "the female prostate"

Abstract

The "female prostate" denotes an impression on the base of the female bladder resembling the enlarged male prostate radiographically. Though the finding is widely recognized, confusion exists as to its significance. The differential diagnosis is moderately extensive, and includes retroverted uterus, anterior vaginal tumors, urethral and bladder floor tumors, benign and malignant bony pelvic lesions, urethral diverticulum, and postsurgical changes. Several cases are presented illustrating the previously mentioned causations. An impression on the floor of the female bladder should not be routinely dismissed as inconsequential without thorough evaluation.
