Oxidized cellulose (Surgicel(R)) has been used as a haemostatic agent
in neurosurgery for five decades. Complications have been few. Two cas
es are reported of granulomatous reaction to oxidised cellulose two mo
nths and twelve months after removal of intracranial meningiomas. Both
appeared as contrast enhancing space occupying lesions on CT scan and
were taken for recurrence of the tumour.
