Inguinal ovary as a rare diagnostic sign of Mayer-Rokitansky-Küster-Hauser syndrome.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is a rare syndrome characterized by complete or partial agenesis of the uterus and vagina, due to a congenital defect of the Mullerian duct. Affected individuals have a 46,XX karyotype and a normal female phenotype. MRKH syndrome may be isolated (type I MRKH syndrome) or associated with renal, cardiac, and skeletal anomalies, short stature, and auditory defects. The latter is defined as type II MRKH syndrome or the Müllerian duct aplasia/hypoplasia, renal agenesis/ectopy, and cervicothoracic somite dysplasia (MURCS) association. The majority of patients with MRKH syndrome present with primary amenorrhea. We report a case of type II MRKH syndrome who has been referred by a pediatric surgeon for detection of gonadal function. During an inguinal hernia operation, the left ovary had been observed in the hernia sac. Clinical and radiological evaluation of the patient showed an absence of the uterus and left kidney, and cervical hemi vertebra. Based on these findings, the patient was diagnosed as having type II MRKH syndrome.
