Abdominal findings on magnetic resonance imaging (MRI) indicate enlarged ovaries, and pituitary MRI scan show scarce but apparent lesions. Abdominal MRI scans obtained before the patient visited our hospital show enlarged and polycystic ovaries of approximately 7 cm in diameter. (A) T2 width, axial view. (B) T2 width, sagittal view. (C) A contrast-enhanced coronal T1-weighted MRI scan obtained 2.5 years before surgery. (D) A contrast-enhanced coronal spoiled gradient recalled acquisition MRI scan obtained 1.25 years before surgery. Coronal (E) and sagittal (F) view images of spoiled gradient echo 3-dimensional T1 sequence obtained 2 months before surgery. No adenoma is detected in the first (C) and second (D) MRI scans; however, the third MRI scan, in which spoiled gradient recalled acquisition was used, shows the presence of a distinct microadenoma located in the middle of the pituitary gland in both coronal and sagittal sections (arrow).
