Brain computerized tomographic angiography (CTA) in axial, sagittal and coronal planes, respectively (a-c). A large isodense mass around the intense enhancement (pseusoaneurysm) indicating a surrounding thrombus, was evident

Furthermore, a large isodense mass around the hyperdense enhancement was revealed, indicating the surrounding thrombus [Figure 1].

The patient was taken to the operating room for resection of the lesion under general anesthesia through a wedge-shaped skin incision encircling the skin ulceration [Figure 3].
