A rare clinical presentation: a pleomorphic xanthoastrocytoma presenting with intracerebral haemorrhage and metastasizing vigorously-case report and review of the literature.

Metastasis of an intracranial tumour is not a common situation in our daily neurosurgical practice. Pleomorphic xanthoastrocytoma is also a rare glial tumour with relatively a favourable prognosis among other CNS pathologies. Here, we present an anaplastic pleomorphic xanthoastrocytoma case which shows both haematogenous and lymphatic metastasis which is described first time in the up-to-date literature. Our case is a 17-year-old male operated for a right occipital intra-axial lesion with a diagnosis of anaplastic pleomorphic xanthoastrocytoma which recurs 5 years later and metastasize vigorously through haematogenous and lymphatic routes. A rare-presenting symptom for this pathology is also intracerebral haemorrhage. This is the ninth case report in the literature which presents initially with this entity.
