Haemorrhagic presentation of low-grade glioma in adults

Intracranial bleeding is rare in patients with low-grade gliomas, above all in adult population. We reviewed the literature of such cases and reported another case of a haemorrhagic low-grade glioma in a 54-year-old woman presenting with a left hemiparesis. Computer tomography (CT) images showed a right basal ganglia haemorrhage with no mass effect. Vascular malformations were ruled out by angiography. Eighteen fluoro–fluoro deossiglucosio (18F-FDG) positron emission tomography (PET/CT) showed a large hypometabolic area corresponding to the lesion. We waited for patient’s improvement. Late magnetic resonance images revealed a low-grade glioma at the bleeding site. Tumour was removed and histopathologic examination revealed a WHO grade II mixed glioma.
