We appreciated the comments about the saccular pseudoaneurysm originating from the fusiform abdominal aneurysm in the Letter to the Editor from Canyigit et al. [1]. We agree with the comment of Canyigit et al. [1] that this kind of pathology is extremely rare and that penetrating atherosclerotic ulcer is the most likely underlying mechanism of its formation [1]. Contrast-enhanced multidetector computed tomography (MDCT) has become the technique of choice to evaluate aortic disease for its specificity, sensibility, and availability [2].

To our knowledge, the total number of described saccular pseudoaneurysms originating from the fusiform abdominal aneurysm has increased to six cases in total [1, 3, 4]. In our previous paper, we have not emphasized this pathological aspect, because the focus of the case report was on revascularization [3]. However, on MDCT follow-up after endovascular treatment the pseudoaneurysmatic sac showed a considerable reduction in volume [3].
