Abstract

Intracranial aneurysm rupture causes subarachnoid hemorrhage in 80% of the cases, and it may be associated with intracerebral hemorrhage and/or intraventricular hemorrhage (IVH) in 34% and 17% of the patients, respectively. However, on rare occasions, aneurysm rupture may be present causing isolate intracerebral hemorrhage or IVH without subarachnoid hemorrhage.

We describe an unusual case of an anterior communicating aneurysm rupture presented with IVH, without subarachnoid hemorrhage.

Although isolated IVH is rare, aneurysm rupture is a possible condition. Patients presenting with head computed tomography revealing IVH without subarachnoid hemorrhage should be promptly investigated with contrasted image exam to identify and treat possible causes, even in the absence of subarachnoid hemorrhage.

Resumo

A ruptura do aneurisma intracraniano causa hemorragia subaracnóidea em 80% dos casos, e pode estar associada a hemorragia intracerebral e / ou hemorragia intraventricular em 34% e 17% dos pacientes, respectivamente. No entanto, em raras ocasiões, a ruptura do aneurisma pode estar presente, causando hemorragia intracerebral isolada ou hemorragia intraventricular, sem hemorragia subaracnóidea. Descrevemos um caso incomum de ruptura de aneurisma de comunicação anterior apresentado com HIV, sem hemorragia subaracnóidea. Embora a hemorragia intraventricular isolada seja rara, a ruptura do aneurisma é uma condição possível. Pacientes que apresentam tomografia computadorizada revelando hemorragia intraventricular, sem hemorragia subaracnóidea devem ser prontamente investigados com exame de imagem contrastada para identificar e tratar possíveis causas, mesmo na ausência de hemorragia subaracnóidea.
