Descending thoracic aortic aneurysm revealing metastasis of a soft tissue fibrosarcoma: a case report and review of the literature

Clotilde Delerce et al. Clin Sarcoma Res. .

Abstract

Background: Review of the first documented case of aortic wall metastasis from a limb sarcoma.

Case presentation: In a 56-year-old woman with a diagnosis of a high-grade limb fibrosarcoma, an aortic metastasis was revealed by a fast growing aneurysm of the descending thoracic aorta. This was managed with an endoprosthesis.

Conclusion: The presence of an aneurysm in a patient with a sarcoma with a high potential for metastasis and poor cardiovascular risk factors should alert physicians.

Keywords: Aortic aneurysm; Aortic metastasis; Soft tissue sarcoma.

a Coronal gadolinium-enhanced T1-weighted image with fat saturation shows a posterolateral muscular mass of the left thigh with both necrotic and enhanced portions (white star); Saccular aneurysm of the descendant thoracic aorta (white head arrows): arterial phase CT scan of the aneurysm with axial view (b), coronal reconstruction (c) and 3D reconstruction (d). e PET-CT image fusion shows FDG uptake (white arrows) around the aneurysm. f Coronal maximum intensity projection (MIP) reconstruction of postoperative CT shows the endoprosthesis (transparent head arrows) and the excluded aneurysmal cavity (transparent arrow)

Follow-up CT scans shows rapid progression of the lateral aortic metastasis (white head arrows) near the endoprosthesis (white arrows). a Initial postoperative CT scan shows a non-enhancing lateral aortic lesion which is difficult to differentiate from an excluded aneurysmal cavity. b One month later CT scan shows an important tumor’s size increase with a minimal peripheral enhancement (b). c Six months later, CT scan shows an important tumor progression
Fig. 3
Fig. 3
CT scan and MRI performed 6 months after endoprosthesis placement show a large lateral aortic tumor mass (white stars) with a progressive contrast enhancement (white arrows). CT scan shows a minimal contrast enhancement on portal phase (a) and an important one on delayed phase (b). Axial non-contrast (c) and gadolinium-enhanced T1-weighted images with fat saturation on arterial phase (d), portal phase (e) and delayed phase (f) show also a progressive tumor enhancement
