Atypical location of a solitary intracranial chondroma without meningeal attachment.

The case of a 19-year-old female patient with a history of severe headache for several months is presented. Computed tomography (CT) as well as magnetic resonance imaging (MRI) revealed an intracranial, space-occupying mass with no meningeal attachment, located in the left frontal lobe. The entire tumour was removed, the pathological examination revealed a chondroma. The origin of this tumour is analysed, the clinical and histological findings are described and the literature is reviewed.
