A symptomatic Rathke's cleft cyst with pituitary apoplexy: a case report]

We encountered a rare case of symptomatic Rathke's cleft cyst associated with pituitary apoplexy. To our knowledge, six cases have been reported in the literature. The mechanism of this symptom is still obscure because of the rare pathological findings concerning Rathke's cleft cysts. Judging from the operative and the histopathologic findings, we speculate that pituitary apoplexy could occur due to hemorrhage from certain vessels such as compressed portal veins or newly organized vessels of the granulation tissue of the cyst wall.
