Lintene granuloma following microvascular decompression mimicking a cerebellopontine angle tumour

We describe a case of foreign body granuloma caused by lintene (cotton gauze), placed during microvascular decompression of the fifth nerve for trigeminal neuralgia. At presentation, the clinical and radiological findings were suggestive of a tumor. This is only the second case in the literature of a foreign body granuloma occurring owing to the placement of a lintene pledget during microvascular decompression.
