Rathke pouch cyst

Quiste de la bolsa de Rathke

Rathke pouch cysts are epithelium-lined cysts arising from the embryological remnants of Rathke´s pouch. They are usually incidentally identified since the majority are asymptomatic. They become symptomatic when they enlarge enough to compress neighbor structures causing headache, visual disturbances and pituitary dysfunction. They occur mostly in adults in the fourth to fifth decades of life. A case is presented in a 9-year-old female patient who consulted for growth retardation to the endocrinology service. She was treated with growth hormone and a magnetic resonance imaging (MRI) scan reported Rathke´s pouch cyst versus pituitary adenoma.
