Dynamic Enhancement Features of Cavernous Sinus Cavernous Hemangiomas on Conventional Contrast-Enhanced MR Imaging

Abstract

BACKGROUND AND PURPOSE:The reported MR imaging characteristics of cavernous sinus cavernous hemangiomas (CSCHs) in the literature are nonspecific. The purpose of our study was to explore dynamic enhancement features of CSCHs on conventional contrast-enhanced MR imaging and to correlate these features with histopathologic subtypes.

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

“…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.…”

Taken together, epidemiological and conventional imaging findings are insufficient to differentiate between these lesions.…”

Resonancia magnética en hipoacusia y vértigo

“…La hemorragia es una complicación común, pudiendo existir diferentes fases evolutivas [15,16]. Se consideran angiomas venosos histoló-gicamente mixtos [14].…”

Imaging Lesions of the Cavernous Sinus

“…Other times, they show nonspecific intense homogeneous or heterogeneous contrast enhancement (Fig 4). [16][17][18][19] Meningioma Most CS meningiomas arise from the lateral dural wall, but sometimes they may be exclusively inside the CS. A meningioma is usually hypo-to isointense with respect to gray matter in all MR imaging sequences and enhances intensely (Fig 5A).…”
