case_images: Additionally, there was close proximity of the tumor to the aortic arch, but vessel wall invasion was not evident according to the radiology report (Figure 1).

case_images: The patient immediately underwent a CT angiography that revealed thrombosis of the infrarenal aorta in the presence of atherosclerotic lesions of the iliac arteries bilaterally (Figure 2).
case_images: (a-c) Fine needle biopsy of the primary lung tumor shows moderately differentiated lung adenocarcinoma: (a) hematoxylin and eosin stain x200, (b) TTF-1 positivity x200 and (c) CK7 positivity x200. (d-f) Carcinomatous invasion of the aortic wall: (d and e) hematoxylin and eosin stain x20 and x40, respectively, and (f) TTF-1 positivity x100. (g-i) Tumoral embolus material that shows tumor aggregates in between fibrin and erythrocytes: (g) hematoxylin and eosin stain x40, (h) hematoxylin and eosin stain x100 and (i) Alcian blue stain demonstrates mucin production by the neoplastic cells, x400.

case_images: Histopathological characteristics of thrombus obtained during embolectomy (Figure 3(g)-(i)) were consistent with the histopathology of the biopsy of the primary lung tumor (Figure 3(a)-(c)). The histopathology of the fraction of tumor adjacent to aortic arch revealed invasion of aortic adventitia (Figure 3(d)-(f)).
