MR of the Diaphragma Sellae 765
The appearance of the diaphragma sellae is described in cryomicrotomic sections and on MR in patients with and without intraand suprasellar masses. On MR, it appears as a thin band of negligible signal that is best shown when adjacent CSF or a mass has greater signal intensity. Its position or absence can be used to differentiate intrasellar masses with suprasellar components from suprasellar m...

متن کاملOrbital Cystic Schwannoma Originating from the Frontal Nerve
Schwannomas of the orbit are very rare benign neoplasms. Intraorbital cystic schwannomas originating from the frontal nerve are even rarer, with only 1 case reported to date. This is most likely due to the fact that, in most cases, the origin of the orbital schwannoma cannot be identified intraoperatively. The nerve origin is usually speculated from histological examination of the specimen and ...
متن کاملIntra- and Suprasellar Epithelial Cysts
The computed tomographic (CT) and pathologic findings in three cases of intraand suprasellar epithelial cysts (symptomatic Rathke cleft cysts) are described. Literature review revealed that the characteristic CT finding is an intra sellar and/or suprasellar low-density mass that mayor may not be enhanced. The enhancement is ringlike or capsular in nature. Whether the cyst wall is enhanced or no...
متن کاملSchwannoma originating from lower cranial nerves: report of 4 cases.
Four cases of schwannoma originating from the lower cranial nerves are presented. Case 1 is a schwannoma of the vagus nerve in the parapharyngeal space. The operation was performed by the transcervical approach. Although the tumor capsule was not dissected from the vagus nerve, hoarseness and dysphagia happened transiently after the operation. Case 2 is a schwannoma in the jugular foramen. The ...
