Isolated Retroperitoneal Deep Infiltrating Endosalpingiosis in Absence of Endometriosis

Abstract

A 36 year-old female presented with a 4-year history of cyclic left lower abdominal pain and severe dyspareunia. Physical exam revealed a 2cm tender, mobile nodule at the left apex of the vagina with normal overlying vaginal mucosa. Magnetic resonance imaging demonstrated a 1.6 × 1.6 × 1.7cm round, solid smooth intramural mass in the bladder base, without mucosal invasion (Figure 1). The patient elected surgical management, with cystoscopy demonstrating a large bulge adjacent to the left ureteral orifice without mucosal involvement (Figure 2).
