Background: Herein, we report laparoscopic excision of a retroperitoneal Mullerian cyst, which is uniquely located medial to the left adrenal gland, mimicking adrenal adenoma in an adolescent girl.
Case: A healthy 13-year-old adolescent girl presented with secondary amenorrhea. Ultrasound and magnetic resonance imaging showed a solid-cystic mass medial to the left adrenal gland. Laparoscopic cyst excision was performed. The histopathological findings were consistent with a benign cyst of Mullerian origin.
Summary and conclusion: To the best of our knowledge, this is the first case report of Mullerian cyst located medial to the adrenal gland in all age groups.
