Abstract
PURPOSE: Extra-axial (dural) cavernomas are rare and constitutes 5% of all cavernomas. They are thought to arise from the venous plexus of the dura. They can reach large sizes before diagnosis and can have an aggressive presentation. METHODS: The authors report a rare case of giant cavernoma based on the posterior fossa dura adjacent to the sigmoid sinus (sino-dural angle) in an 8-year-old boy which was excised with good outcome. The authors describe its clinico-radiological profile and outcome characteristics along with a comprehensive review of relevant literature. RESULTS: This child underwent retromastiod craniectomy and complete excision of the dural cavernoma. The dural attachment was coagulated. Histopathological examination confirmed the diagnosis. CONCLUSION: We report cavernoma needs to be considered in the differential diagnosis of a dural-based posterior fossa lesion in paediatric population as complete excision is possible.
