Urachal endometrioma: A case report

Abstract

Introduction. We discuss a rare presentation of an unusual case of endometrioma. Case presentation. A 40-year-old Caucasian woman presented with subacute abdominal pain and a suprapubic mass. A final diagnosis was made after the mass was resected and histopathology confirmed an endometrioma originating from an urachal remnant. Select imaging studies and histopathology are presented in this case report. Conclusion. While endometriomata are well known to arise from abdominal scars, the condition described in this case report is a rare example of an endometrioma arising from the urachus. A review of the pathological complications of the urachus is also included. © 2009 Browne et al; licensee BioMed Central Ltd.
