Home > Conditions > Rathke’s Cleft Cyst
Rathke’s cleft cysts—or RCCs—are lesions located at the base of the brain. They are thought to occur when part of the embryonic Rathke’s pouch, which develops in the roof of the mouth, is leftover. Rathke’s cleft cysts are benign growths.
Rathke’s Cleft Cyst Symptoms:
Rathke’s cleft cysts often produce no symptoms. Patients with symptoms usually have a large Rathke’s cleft cyst that is pressing on other parts of the brain, like the pituitary gland. These symptoms typically include:
- Vision problems, such as reduced visual acuity, loss of part of the visual field or peripheral vision
- Endocrine symptoms, such as unbalanced hormones, diabetes insipidus and menstrual cycle disruptions
Rathke’s cleft cyst are rare but most commonly appear in adults. To diagnose Rathke’s cleft cyst, an MRI or CT scan is needed.
