Cavernous angioma of the cavernous sinus: imaging findings.
Cavernous angiomas (cavernomas) of the cavernous sinus are uncommon, with only scattered reports in literature. Unlike their parenchymatous counterparts, they are intensely enhancing para-sellar masses, iso/hypointense in T1- and hyperintense in T2-weighted images. Differential diagnosis with para-sellar meningiomas and schwannomas can be difficult. We report three cases of this condition, desc...

متن کاملCharacteristic MR imaging findings of cavernous hemangiomas in the cavernous sinus.
Cavernous hemangiomas occur very rarely in the cavernous sinus and are difficult to diagnose preoperatively. MR images obtained in five patients with surgically verified cavernous hemangiomas in the cavernous sinus were reviewed. MR images showed hypointensity on T1-weighted images and well-defined hyperintensity on T2-weighted images with marked homogeneous enhancement after contrast material ...
متن کاملThird ventricular cavernous angioma.
Third ventricular cavernous angiomas are rare vascular malformations of the brain. We report an eight-year old boy with a rare third ventricular cavernous angioma that hemorrhaged presenting with symptoms of acute hydrocephalus. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) showed a heterogenous ill-defined, solid and cystic intraventricular mass in the third ventricle which was...
متن کاملVenous Angioma, Cavernous Angioma, and Hemorrhage
In this issue of AJNR, Wilms et al ( 1) add to the ongoing debate whether the venous angioma, more recently called developmental venous anomaly (2), can be symptomatic, whether it alone can bleed, or whether such hemorrhage occurs because of the concomitant occurrence of a cavernous angioma . This debate is not just semantic. It is essential to pathophysiologic understanding of a given lesion s...
