Giant aneurysms (GA) of middle cerebral artery (MCA) are rare and account for approximately 0.5-4.8% of intracranial artery aneurysms. Early diagnosis of brain GA is critical. Classic digital subtraction angiography (DSA) with the option of three-dimensional rotational angiography remains the “gold standard” in the diagnosis of intracranial aneurysms, including GA. The primary goal of brain GA treatment is to permanently exclude the aneurysm from the circulation while preserving the flow in the candelabra. The secondary goal is to stop the growth of the aneurysm and reduce the ‘mass effect’ symptoms it causes. Despite new endovascular techniques and advances in microsurgery, the treatment of GA MCA is still a therapeutic challenge. There are only a few reports in the literature describing cases of patients diagnosed with GAs of MCA and evaluating various treatment methods. In this article, we present the case of a 78-year-old patient with GA of the right MCA, who underwent effective embolization of the active part of the aneurysm.
