Angiosarcoma of the Abdominal Aorta After Endovascular Aneurysm Repair

Abstract

Primary angiosarcomas of the aorta are rare, highly aggressive malignant tumors for which there have been limited documented cases in the medical literature. Diagnosis is challenging due to nonspecific symptomatology and imitation of common aortic pathologies. A subset of these primary aortic angiosarcoma cases is seen in association with endovascular aneurysm repair, or EVAR; however, the connection between the 2 entities is not completely understood. Here, we present 18F-FDG PET/CT imaging findings of an angiosarcoma of the aorta in a 69-year-old man status post EVAR.

Rapid Progression of Angiosarcoma in a Man with a Left Psoas Muscle Hematoma and a Recent EVAR of Abdominal Aorta

“…Other risk factors are some familial syndromes (neurofibromatosis, Maffucci syndrome and Klippel-Trenaunay syndrome), exposure to toxins (vinylchloride, thorium dioxide, arsenic, anabolic steroids) and f oreign substances (accidentally retained surgical gauzes, vascular and orthopaedic prostheses and gouty tophus). A correlation between vascular grafts and aneurysms on the site of the graft has also been suggested in literature (4)(5)(6)(7)(8)(9)(10)(11)(12)(13).…”

Primary Hepatic Angiosarcoma Having FDG Uptake at the Similar Level of the Normal Liver Parenchyma

“…[3][4][5] Angiosarcoma of the abdominal aorta, skin, spleen, breast, and heart also showed intense FDG activity. [6][7][8][9][10] However, this case indicates that hepatic angiosarcoma does not necessarily present with increased FDG activity than the normal liver, and it should be taken into consideration as one of the possibilities in multiple hepatic masses with mild FDG activity.…”

Primary Aortic Epithelioid Angiosarcomas With Metastatic Disease Detected by 18F-FDG PET/CT

“…1,2 Angiosarcoma is a malignant tumor derived from vascular endothelial cells or mesenchymal cells. Primary aortic epithelioid angiosarcoma is extremely rare, [3][4][5][6] which can be mimicked as atheroembolic disease. [7][8][9] The pathological examination was very crucial for the diagnosis; however, a biopsy may be obtained from distant metastases or neoplastic embolism.…”
