title: Could Parkinsonism complicate craniotomy and excision of convexity meningioma? A case report.
abstract: Parkinsonism is a neurodegenerative clinical disorder characterized by varying combinations and degrees of rest tremor, rigidity, slowing of voluntary movements and postural instability. Amongst the aetiologic factors, massive post-craniotormy haematoma has not been previously considered. This report is to arouse the suspicion that vascular displacement in the midbrain resulting from a massive unilateral intracranial haematoma could lead to the unusual complication of Parkinsonism. This is the report of a 55-year old retired male banker, without any previously identifiable risk factor except for his age, who developed Parkinsonism following a huge acute extradural haematoma that complicated a craniotomy for the excision of a haemorrhagic convexity meningioma. The patient was placed on medical treatment resulting in a slow but progressive neurological improvement. Reports of Parkinsonism following post-tumour excision are probably, very rare. We, hereby, report a case of Parkinsonism complicating a gross total excision of a convexity meningioma.
