“…CH is more a hamartoma or vascular malformation rather than a neoplasia [3]. Although CH is very rare, CH of the cavernous sinus present like tumors and there can be a medial extension into the sella [7].…”

“…Intrasellar CH's may be symptomatic or asymptomatic. In the literature, besides asymptomatic cases one of which was found during autopsy [4] and another found incidentally, cranial nerve palsies caused by cavernous sinus extension [3,7,8] or secondary vision problems due to optic chiasm compression [9] were reported.…”

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.

“…5 Meningiomas and cavernous haemangiomas often share a similar appearance on conventional pre-and postcontrast MRI sequences: hypo-or isointensity on T 1 WI, slight to prominent hyperintensity on T 2 WI, a homogeneous or heterogeneous appearance, homogeneous or heterogeneous enhancement on postcontrast T 1 W1, and occasional flow voids and dural tails. 25 Around 66.7-87.5% of parasellar cavernous haemangiomas are misdiagnosed as meningiomas, 26,27 and parasellar meningiomas (particularly angiomatous meningiomas) are often mistaken for cavernous haemangiomas. 28 Both meningiomas and parasellar cavernous haemangiomas have a propensity to occur in middle-aged women, 25 which is in accordance with the findings of the present study where patients had a mean age of 47.5 years and a strong female bias.…”

The role of magnetic resonance diffusion-weighted imaging and three-dimensional arterial spin labelling perfusion imaging in the differentiation of parasellar meningioma and cavernous haemangioma

et al. 2014

Objective: To evaluate the diagnostic value of magnetic resonance diffusion-weighted imaging (DWI) and three-dimensional arterial spin labelling perfusion imaging (3D-ASL) in distinguishing cavernous haemangioma from parasellar meningioma, using histological data as a reference standard. Methods: Patients with parasellar meningioma or parasellar cavernous haemangioma underwent conventional T 1 -and T 2 -weighted magnetic resonance imaging (MRI) followed by DWI and 3D-ASL using a 3.0 Tesla MRI. The minimum apparent diffusion coefficient (minADC) from DWI and the maximal normalized cerebral blood flow (nCBF) from 3D-ASL were measured in each tumour. Diagnosis was confirmed by histology. Results: MinADC was significantly lower and nCBF significantly higher in meningioma (n ¼ 19) than cavernous haemangioma (n ¼ 15). There was a significant negative correlation between minADC and nCBF (r ¼ À0.605). Conclusion: DWI and 3D-ASL are useful in differentiating cavernous haemangiomas from parasellar meningiomas, particularly in situations when the appearance on conventional MRI sequences is otherwise ambiguous.
