The tumor appeared to be growing in the vicinity of the pituitary as evidenced by a small portion of Rathke's cleft epithelium.
Adrenal computed tomography (CT) revealed bilateral adrenal hyperplasia and pituitary magnetic resonance imaging (MRI) demonstrated a hypointense lesion, 7 x 4 mm in size, on the right side of the pituitary gland (Figure 1a and Figure 2) and a cystic lession, 4 mm in size, consistent with Rathke's cleft cyst in the central part of the pituitary (Figure 1b).
