Urachal endometrioma: a case report

Abstract

IntroductionWe discuss a rare presentation of an unusual case of endometrioma.Case presentationA 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.ConclusionWhile 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.

Umbilical Endometriosis With Urachal Remnant

Physicians should consider umbilical endometriosis in the differential diagnosis of nodules appearing over ϫ200).…”
