[Cocaine abuse as precipitating factor of tumoral bleeding in an oligoastrocitoma]

Cocaine abuse has been associated with a variety of intracranial haemorrhagic disorders, such as intracerebral, subdural or subarachnoidal haemorrhage. Frequently, these patients harbour underlying vascular malformations, like cerebral aneurysms or arteriovenous malformations (AVM). To the best of our knowledge only two cases of tumoral haemorrhage induced by cocaine abuse have been previously reported. We describe a new case of intracerebral haemorrhage after cocaine inhalation, in which both the preoperative imaging studies and the pathological examination showed a brain tumour as the origin of the haemorrhage. We think that cocaine abuse may be considered as a new precipitating factor in intratumoral haemorrhage.
