Undiagnosed Endometriosis: A Rare Case of Frozen Pelvis

A 40-year-old woman, para two live two, arrived at the emergency room complaining of dysmenorrhoea for three years and postcoital bleeding for four years. She had no previous history of any operation. Her presentation was consistent with acute pain in the abdomen, and she took treatment for that, but it was not relieved. She had no significant family history. Her vital signs, urinalysis, and complete blood count were within normal limits. Her ultrasonography report showed a bilateral ovarian cysts with a 12-week-sized uterus [Table/Fig-1]. The differential diagnoses of frozen pelvis included pelvic inflammatory disease, pelvic adhesion disease, recurrent ovarian cysts, leiomyoma, adenomyosis, and hydrosalpinx.
