Cavernous haemangioma of cavernous sinus : a diagnostic and therapeutic challenge

Cavernous haemangiomas of cavernous sinus are very rare and behave differently from the much commoner parenchymal cavernous haemangiomas. They resemble meningiomas on CT Scan and MRI. Although they appear avascular or mildly vascular on DSA studies they bleed profusely during excision and carry a high morbidity and mortality. These tumours are usually limited by the dura and do not breach it. C.S.F. rhinorrhoea as a presentation is being reported for the first time. The diagnostic and management difficulties are discussed with presentation of two cases and a brief review of literature.
