Rathke's cleft cyst in two girls with precocious puberty

Rathke's cleft cysts arise from remnants of Rathke's pouch and are usually found incidentally on MRI or autopsy. In childhood, the most common presenting symptoms of Rathke's cleft cysts are endocrine abnormalities, such as reduced growth hormone secretion, hyperprolactinemia, or diabetes insipidus. Non-specific symptoms, such as headache and visual disturbance, may also occur. Although precocious puberty has occasionally been described in association with suprasellar lesions, such as hamartomas, arachnoid cysts, and craniopharyngiomas, to our knowledge there have been no documented cases secondary to Rathke's cleft cysts. We report here two patients, both of whom presented with precocious puberty, and were found to have Rathke's cleft cysts.
