The giant aneurysm of the cavernous internal carotid artery is an uncommon event. In the case of giant aneurysmal formation, the patient presents with some signs or symptoms, reported or observed on physical examination, which reveal a possible mass effect with neurovascular compression of the aneurysm, or even a subarachnoid hemorrhage due to the rupture of the aneurysm. We report the case of a 69-year-old patient who was admitted to the emergency department, referred by the basic health unit (BHU) of her locality for neurosurgical evaluation after suffering a mild traumatic brain injury (TBI). The patient, who was asymptomatic, carried with her a tomographic computerized examination of the skull, performed one day after the incident, evidencing left nodular parasellar lesion involving the cavernous sinus, discovered at random. After more specific clinical, laboratory and imaging exams, she was diagnosed with a giant aneurysm of the cavernous segment of the left internal carotid artery (LICA) and was submitted to endovascular embolization for correction.
Hemorragia intracerebral (HIC) é um evento responsável por cerca de 15% de todos os acidentes vasculares cerebrais. Quando associadaà hemorragia intraventricular trata-se de eventos caóticos com altas taxas de morbidade e mortalidade. Relata-se o caso de um pacientede 64 anos que deu entrada no setor de emergência com quadro convulsivo e rebaixamento do nível de consciência. Após o diagnósticotomográfico de HIC associado a hemoventrículo e hidrocefalia aguda foi realizada derivação ventricular externa (DVE) em caráter deurgência e, após tomografias seriadas, optou-se por realizar terapia fibrinolítica intraventricular com Alteplase devido à refratariedadeda absorção do hematoma. Após duas doses de fibrinolítico houve melhora da imagem tomográfica com resolução quase completa docoágulo, não havendo nehuma complicação relacionada ao tratamento específico. Paciente teve alta para enfermaria em treze dias, semdependência do cateter de DVE, mas acabou falecendo por complicações respiratórias após duas semanas.
