Five years prior, an abdominal endovascular aneurysm repair (EVAR) was performed, followed by an open repair with proximal graft interposition due to an endoleak type IA two years ago. Laboratory tests revealed only moderately elevated infection markers (CrP 66 mg\/L, WBC 14 GPt\/L). 18F-FDG PET\/CT showed a hypermetabolic peri-aortic mass initially suspected to be inflammatory. However, the patient did not exhibit signs of fever. Because of the equivocal constellation, a fine-needle biopsy was conducted, revealing malignant cells. The patient underwent complete tumor resection including aortic replacement. Histopathology confirmed the diagnosis of an angiosarcoma. The treatment was then supplemented with chemotherapy using doxorubicin and ifosfamide.<\/jats:p>","DOI":"10.3390\/diagnostics16152325","type":"journal-article","created":{"date-parts":[[2026,7,24]],"date-time":"2026-07-24T13:53:26Z","timestamp":1784901206000},"page":"2325","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Primary Angiosarcoma of the Abdominal Aorta Following Endovascular Aneurysm Repair Mimicking Vascular Graft Infection"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-4730-4996","authenticated-orcid":false,"given":"Marcel","family":"Wehmann","sequence":"first","affiliation":[{"name":"Clinic of Nuclear Medicine, Jena University Hospital, 07747 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6462-3851","authenticated-orcid":false,"given":"Martin","family":"Freesmeyer","sequence":"additional","affiliation":[{"name":"Clinic of Nuclear Medicine, Jena University Hospital, 07747 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anika","family":"Biermann","sequence":"additional","affiliation":[{"name":"Section Pathology, Institute of Forensic Medicine, Jena University Hospital, 07747 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00fcrgen","family":"Zanow","sequence":"additional","affiliation":[{"name":"Department of General, Visceral and Vascular Surgery, Jena University Hospital, 07747 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mika","family":"Henkenjohann","sequence":"additional","affiliation":[{"name":"Department of General, Visceral and Vascular Surgery, Jena University Hospital, 07747 Jena, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"373","DOI":"10.1053\/j.semnuclmed.2017.02.009","article-title":"Dual-time point (18)F-FDG-PET and PET\/CT for Differentiating Benign From Malignant Musculoskeletal Lesions: Opportunities and Limitations","volume":"47","author":"Parghane","year":"2017","journal-title":"Semin.
