Imaging analysis. A. Chest computed tomography (CT) shows lesion at the apex of the left lung (yellow arrow). B. Abdominal CT shows a left adrenal lesion (yellow arrow). C, D, E, F. ¹⁸F-fluorodeoxy glucose positron emission tomography (¹⁸F-FDG PET) / CT. Arrows indicate high uptake in the pituitary gland (C), left lung lesion (D), and bilateral adrenal glands (E and F). G and H. Pre-treatment pituitary T1-weighted magnetic resonance imaging (MRI). G. Coronal section. H. Sagittal section. Suprasellar lesion (φ13 mm) and thickening of the pituitary stalk (circled in yellow). I and J. Post-treatment pituitary T1-weighted magnetic resonance imaging (MRI). I. Coronal section. J. Sagittal section. After chemotherapy, pituitary lesion disappeared (circled in red).
