A case of florid intracerebral reaction to haematoma mimicking a tumour

We present a patient with a suspected intracerebral malignant lesion admitted with signs and symptoms of an intracerebral mass lesion and managed operatively. Histological diagnosis demonstrated papillary endothelial hyperplasia (Masson's tumour). This highlights the ability of benign reactive processes associated with intracerebral haematoma to clinically and radiologically mimic neoplastic lesions.
