Pituitary MRI showed a pituitary mass. The pelvic ultrasound examination and CT scan showed a right ovarian cyst. The subsequent thyroid hormone replacement was associated with a clinical, a biological and radiological resolution. It was a pituitary and ovarian mass syndrome secondary to primary hypothyroidism.
