case_images: Pre and postoperative magnetic resonance imaging. (a) T1 gadolinium with an intrasellar cystic image with peripheral enhancement, intracystic nodule without septum or compartments. (b) Inverted T2 showing the displacement of the chiasm and the anterior communicating complex as well as the intra-lesional fluid level, arrow in figure b refers to "nodule" too. (c) Immediate postoperative T1 gadolinium with evidence of an intact pituitary stalk as well as persistence of peripheral enhancement that may correspond to the pituitary gland. (d) T2 inverted with improvement in the disposition of the chiasm and the anterior communicating complex.

case_images: Displacement of the optic chiasm and the anterior communicating complex were observed, as well as intralesional fluid level [Figure 1].
case_images: Intraoperative images of the endoscopic endonasal approach. (a) U-shaped dural incision. (b) Dissection of the anterior, lateral, and inferior walls of Rathke's cleft cyst capsule. (c) Drainage of cyst contents. (d) Dissection and total removal of the capsule. (e) Surgical bed demonstrating total resection of the capsule with integrity of the arachnoid membrane and residual pituitary. (f) Nasoseptal flap rotation.

case_images: The tumor was fully resected without complications or incidents [Figure 2].
case_images: (a-c) A predominantly lymphocytic inflammatory process is identified, with macrophages with clear and extensive cytoplasm (xanthocytes) and giant cells within a fibrous wall, which does not show epithelial lining, and displaces the normal pituitary gland. (d) Reticulin stain confirms the normal architectural distribution of the pituitary gland.

case_images: Histological examination revealed a chronic xanthogranulomatous process with a fibrous wall and epithelial lining compatible with Rathke's pouch cyst [Figure 3].
