Secondary Parkinsonism Due to a Large Anterior Cranial Fossa Meningioma

Secondary Parkinson’s disease or subacute Parkinson’s may occur after stroke, drug overdose carbon monoxide or manganese toxicity, and rarely owing to a brain tumor. Loss of dopaminergic neurons in the substansia negra pars compacta (SNc), or presence of the proteinaceous inclusions called Lewy bodies are thought to be the cause of Parkinson’s disease. Notwithstanding, in the past few decades, many case reports have been published describing Parkinson’s symptoms following either stroke, ischemia, toxicity, brain haemorrhage or rarely neoplasm. LEARNING POINTS: Brain tumours can cause secondary parkinsonism. This type of secondary parkinsonism improves when the tumour is removed.
