Avitene, generically termed microfibrillar collagen, is a surgical hemostatic agent. Collagen-based hemostats are widely used to trigger platelet aggregation and reinforce the fibrin clot. Rarely, Avitene has been reported to induce a granulomatous reaction in the CNS, usually as a mass-forming lesion known as a textiloma. We report a case of Avitene-induced granulomatous inflammation presenting as meningitis after neurosurgery for WHO grade II atypical meningioma.
