Intrasellar cavernous hemangioma is an extremely rare lesion. It is usually confused with pituitary adenoma, both clinically and radiologically. It is important to differentiate intrasellar cavernous hemangioma from pituitary tumors because of the risk of severe hemorrhage during operation and the possible complications in the postoperative period. Magnetic resonance imaging characteristics of the lesion may be helpful in differential diagnosis. In this report, we present the magnetic resonance imaging findings of a cavernous hemangioma case, which is totally intrasellar located.

“…18 Although progressive contrast "filling in" in cavernous sinus lesions on conventional contrast-enhanced sequences is not specific, it is suggestive of the diagnosis of CSCHs. 19 As for lesions in which progressive contrast "filling in" cannot be ascertained, a postcontrast delayed MR image is suggested for further evaluation.…”

“…On the other hand, the lateral sellar lesion, like the mass in the pituitary gland, was enhanced early, homogeneously and intensely. Suzuki performed dynamic MRI study of lesions adjacent to the pituitary gland, and reported that intracavernous CAs appeared as peripheral nodular stains with gradually increasing intensity [4]. In our case, dynamic study showed very early staining, as the staining pattern was nodular and gradual, we considered it as CA.…”

We encountered a 49-year-old female presenting with left oculomotor palsy who was found to be co-localized cavernous sinus CA and pituitary adenoma. Although cavernous angiomas (CA) originated from parasellar regions are not so rare, on neuroimaging studies, the characteristics of CA may be difficult to differentiate from those of pituitary adenomas. The co-localization of the two tumors was identified by preoperative dynamic MRI study. As intraoperative histological examination confirmed our preoperative diagnosis, we performed biopsy of the CA only to avoid uncontrollable intraoperative hemorrhage.
