Summary: After coil embolization for an aneurysm, edema surrounding the aneurysm revealed by magnetic resonance imaging (MRI) is rarely seen and is usually associated with neurological symptoms. Perianeurysmal edema was found by postoperative MRI in three out of 182 patients with cerebral aneurysm, which was treated with Guglielmi Detachable Coil (GDC), and neurological symptoms developed simultaneously. In cases where neurological symptoms improved with conservative medical treatment, a temporary increase in the volume of an aneurysm, due to coil and thrombus formation, may result in edema. In cases where symptoms were not alleviated with conservative medical treatment, persistent water-hammer effect against the residual lumen of the aneurysm as well as an increase in the volume of aneurysm by hemorrhage in the aneurysmal wall may contribute to the development of perianeurysmal edema. Consideration of the mechanism of edema development by neurological symptoms, MRI findings, and angiographic findings is needed in order to select appropriate treatment. |
