Case report: primary mesenchymal chondrosarcoma of the brain.

ABSTRACT

We report an 11-year-old girl with a very rare tumour, mesenchymal chondrosarcoma of the brain, presenting as a haemorrhagic stroke, in whom angiography originally showed a distal arterial aneurysm. One month later MRI showed a solid tumour in addition to evidence of haemorrhage, and angiography then demonstrated pathological vascularity. The diagnosis was made following craniotomy.
