Acute late presentation of a functioning non-communicating rudimentary uterine horn containing an adenomyosis: A case report.

A functioning noncommunicating rudimentary horn is a rare uterine malformation. The presence of rudimentary uterine horn with adenomyosis is even rarer situation. Clinical presentation varies from mild pain that might present late in the clinical course with complications that can be gynecological such as pelvic pain and endometriosis or obstetrical such as preterm delivery, cesarean section, and ectopic pregnancy. We are reporting a case of a young woman who presented with acute abdominal pain that was superimposed by chronic pelvic pain due to endometriosis and deep pelvic vein thrombosis secondary to an enlarging noncommunicating rudimentary uterine horn containing extensive adenomyosis. With the help of MRI, initial diagnosis was given as rudimentary functioning horn containing fibroid and unilateral renal agenesis. The treatment comprised complete laparoscopic excision of the entire horn, and the patient reported significant improvement afterward. Final histopathology was rudimentary horn containing adenomyosis. Our paper is one of few papers reported adenomyosis in function noncommunication rudimentary horn.
