title: [Chondroma adjacent to Meckel's cave mimicking a fifth cranial nerve neurinoma. A case report].
abstract: Cranial chondromas are tumours arising from chondrocyte embryonic remnants cells that usually appear in the skull base synchondrosis. In contrast to the rest of the organism, where chondroid tumours are the most common primary bone tumour just behind the haematopoietic lineage ones, they are a rarity at cranial level, with an incidence of less than 1% of intracranial tumours. The case is reported on a 42 year-old male referred to our clinic due to the finding of an extra-axial lesion located close to the Meckel's cave region, with extension to the posterior fossa and brainstem compression after progressive paraparesis of 6 months onset. With the diagnosis of trigeminal schwannoma, a subtotal tumour resection was performed using a combined supra-infratentorial pre-sigmoidal approach. The postoperative histopathology report confirmed the diagnosis of cranial chondroma.
