Resumen

El consumo de cocaína ha sido implicado en una serie de efectos sobre el SNC, entre los que destacan los ictus hemorrágicos. Estas hemorragias se producen más frecuentemente en pacientes en que se demuestra patología vascular previa, especialmente aneurismas y malformaciones arteriovenosas (MAV) cerebrales. En nuestra revisión de la literatura, sólo hemos encontrado, hasta el momento, dos casos de hemorragia cerebral inducida por cocaína en que la patología de base haya sido un tumor. Presentamos un nuevo caso de hemorragia cerebral producida pocas horas después del consumo por vía nasal de importantes dosis de cocaína, en el que los estudios preoperatorios así como el estudio anatomopatológico revelaron la existencia de un tumor cerebral como origen de la hemorragia. Consideramos que la cocaína puede ser tomada en cuenta como un nuevo factor precipitarte de hemorragia tumoral.

Summary

Cocaine abuse has been associated with a variety of intracranial haemorrhagic disorders, such as intracerebral, subdural or subarachnoidal haemor-rhage. Frecuently, these patients harbour underlying vascular malformations, like cerebral aneurysms or arteriovenous malformations (AVM). To the best of our knowledge only two cases of tumoral haemor-rhage 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.

Key words:
Intracerebral haemorrhage
Cocaine
Intratumoral haemorrhage
