Initial brain magnetic resonance imaging (MRI) with and without contrast: Postcontrast sagittal (a) and coronal (b) images of homogeneously enhancing diffuse enlargement of the pituitary gland, with somewhat irregular boundaries, measuring up to 1.8 cm in size, and a mild smooth thickening with enhancement involving the pituitary infundibulum. No associated hemorrhage.

A brain magnetic resonance imaging (MRI) with and without contrast was obtained (Figure 1a and b), showing diffuse granulomatous involvement of the pituitary gland consistent with sarcoidosis, and prominence of the bilateral lacrimal glands, reduced in size compared with previous CT, with increased T2 signal within the right lacrimal gland.
Brain magnetic resonance imaging (MRI) with and without contrast post-therapy: Postcontrast sagittal (a) and coronal (b) images showing pituitary lesion resolution, with no new lesions. Pituitary measures 4 mm in height in the midline and approximately 6 mm along the lateral aspects, with a broad 1.3 cm transverse dimension.

Six months later, a follow-up brain MRI with and without contrast (Figure 2a and b) showed complete resolution of the pituitary and infundibular lesions.
