Rathke cleft cyst RCC is an epithelium-lined benign congenital cystic lesion found in the sellar or suprasellar area. Macroadenoma was felt to be less likely due to lack of cavernous sinus invasion and the uniformly thin wall of this lesion. 12 rows Rathke cleft cysts are remnants of the Rathke pouch a structure of ectodermal origin formed. In the cases that. Occasionally this remnant gives rise to a large cyst called the Rathkes cleft cyst RCC. Their incidence has been underestimated before.

It is concluded that MRI is an efficient tool for diagnosis allowing appropriate medical decision making in Rathkes cleft cyst cases based on a retrospective review of 12 cases and a review of the literature. In the sella Rathke pouch gives rise to the adenohypophysis anteriorly and intermediate lobe of the pituitary gland posteriorly. Rathke cleft cyst RCC apoplexy is an uncommon type of lesion that is challenging to diagnose without histopathological samples. Differentiation with MR imaging of a cystic or hemorrhagic pituitary adenoma from a Rathke cleft cyst RCC remains a common issue. Rathke cleft cysts RCCs are benign sellar and suprasellar lesions commonly presenting as asymptomatic incidental findings. To report a case of uncommon presentation of hemorrhagic Rathkes cleft cyst RCC extending into the cavernous sinus causing diplopia.

9 12 Depending on its cystic content and the presence of an associated intracystic nodule an RCC may show various signal. The correlation of gross and pathologically identified hemorrhagic products in the patients included provides a very good correlation with the radiographic findings and further helps clarify the fact that although most Rathkes cleft cysts have evidence of high proteinaceous fluid which can mimic hemorrhage there are certain cysts that present with an actual hemorrhage. Up to 10 cash back Malignant transformation of a Rathkes cleft cyst has never been described. PURPOSE Rathkes cleft cysts are non neoplastic lesions of the sellar area that seldom are symptomatic. To review a series of hemorrhagic RCCs for physicians encountering this rare presentation.
