| Discussion | Dx. Cavernous hemangioma in the cavernous sinus Extraaxial cavernous hemangiomas are rare and very rarely arise in the cavernous sinus. Cavernous hemangiomas can grow extra-axially within dural sinuses, particularly the cavernous sinus and present like tumors. The most likely growth mechanism is considered to be progressive ectasia of the blood vessels or their autonomous development at the edges of the lesion; hemorrhagic onset is much rarer in hemangiomas of the cavernous sinus than in the intraparenchymal variety. Characteristic MR imaging findings of cavernous hemangiomas in this location include hypo-intensity on T1-weighted images, marked hyperintensity on T2-weighted images and typical enhancement pattern. Dynamic MR imaging demonstrated the peripheral nodular stains gradually increased during the dynamic study. References 1. Sohn CH, Kim SP, Kim IM, Lee JH, Lee HK.
