Haemangioma of Cavernous Sinus- A Case Series

Abstract

Extra-axial cavernous sinus haemangioma are rare extra-axial parasellar lesions. These are non-neoplastic lesions, but can behave in a manner like that of neoplastic lesions as their slow growth with progressive enlargement of thin-walled vascular channels may result in extrinsic compression on adjacent retro-orbital neural structures. It is important to diagnose these lesions preoperatively as surgery in these lesions is often complicated by incomplete removal, severe intraoperative haemorrhage and significant operative morbidity and mortality. A parasellar lesion showing homogeneous markedly increased signal on T2 or proton density weighted images with progressive centripetal “filling-in” with contrast on dynamic Magnetic Resonance Imaging (MRI) should suggest the diagnosis. We are presenting three interesting cases of cavernous sinus haemangioma.
