Primary Aortic Angiosarcoma: A Review of Two Cases Highlighting Unique Imaging and Clinical Characteristics.

Radiol Cardiothorac Imaging 2021 Aug 29;3(4):e210040. Epub 2021 Jul 29.

School of Medicine (C.H.K.), Department of Diagnostic Radiology (A.P.S.L., C.F.), Knight Cancer Institute (M.W., L.E.D.), and Department of Orthopaedics & Rehabilitation (K.R.G.), Oregon Health and Science University, 3181 SW Sam Jackson Park Rd, Portland, OR 97239; and Operative Care Division, Portland VA Medical Center, Portland, Ore (K.R.G.).

Angiosarcomas are rare vascular connective tissue tumors originating from the tunica intima, media, or adventitia and may arise in large vessels. Here two cases of primary angiosarcoma of the aorta are described that highlight initial manifestations and unique complications from diffuse arterial tumor emboli, which led to delayed cancer diagnosis. In patients with aortic lesions, imaging characteristics must be thoughtfully reconciled with clinical scenarios, particularly in patients with no additional evidence of atherosclerosis or vasculitis.

Optimization of a protocol for contrast-enhanced four-dimensional computed tomography imaging of thoracic tumors using minimal contrast agent.

Strahlenther Onkol 2021 Sep 2. Epub 2021 Sep 2.

Department of Oncology, Xinqiao Hospital, Army Medical University, Chongqing, China.

Purpose: The accuracy of target delineation for node-positive thoracic tumors is dependent on both four-dimensional computed tomography (4D-CT) and contrast-enhanced three-dimensional (3D)-CT images; these scans enable the motion visualization of tumors and delineate the nodal areas. Combining the two techniques would be more effective; however, currently, there is no standard protocol for the contrast media injection parameters for contrast-enhanced 4D-CT (CE-4D-CT) scans because of its long scan durations and complexity. Thus, we aimed to perform quantitative and qualitative assessments of the image quality of single contrast-enhanced 4D-CT scans to simplify this process and improve the accuracy of target delineation in order to replace the standard clinical modality involved in administering radiotherapy for thoracic tumors.

Association between nuclear grade of renal cell carcinoma and the aorta-lesion-attenuation-difference.

Abdom Radiol (NY) 2021 Aug 31. Epub 2021 Aug 31.

Department of Urology, University of Florida College of Medicine, Gainesville, FL, 32610, USA.

Introduction And Background: Several features noted on renal mass biopsy (RMB) can influence treatment selection including tumor histology and nuclear grade. However, there is poor concordance between renal cell carcinoma (RCC) nuclear grade on RMB compared to nephrectomy specimens. Here, we evaluate the association of nuclear grade with aorta-lesion-attenuation-difference (ALAD) values determined on preoperative CT scan. Read More

Elective nodal radiotherapy in prostate cancer.

Lancet Oncol 2021 08;22(8):e348-e357

Department of Radiation Oncology, Gustave Roussy Institute, Paris, France.

In patients with prostate cancer who have a high risk of pelvic nodal disease, the use of elective whole pelvis radiotherapy is still controversial. Two large, randomised, controlled trials (RTOG 9413 and GETUG-01) did not show a benefit of elective whole pelvis radiotherapy over prostate-only radiotherapy. In 2020, the POP-RT trial established the role of elective whole pelvis radiotherapy in patients who have more than a 35% risk of lymph node invasion (known as the Roach formula). Read More

Intestinal Autotransplantation and In-Situ Resection of Recurrent Pancreatic Head Intraductal Tubulopapillary Neoplasm with Portal Cavernoma: A Case Report.

Transplant Proc 2021 Oct 14;53(8):2598-2601. Epub 2021 Jul 14.

Department of Anesthesia, University of Miami/Jackson Memorial Hospital, Miami, Florida.

Background: Intraductal tubulopapillary neoplasm (ITPN) is a new entity of a rare premalignant pancreatic neoplasia, and a radical curative resection is indicated. As with other tumors of the root of the mesentery, the proximity of the lesion to large splanchnic vessels, abdominal aorta, and inferior vena cava poses major risks of a massive hemorrhage and visceral ischemia using conventional surgical techniques. At times, these lesions are amenable for resection using novel techniques developed from organ transplantation. Read More

Pathology of the Aorta and Aorta as Homograft.

J Cardiovasc Dev Dis 2021 Jun 29;8(7). Epub 2021 Jun 29.

Department of Cardiac, Thoracic, Vascular Sciences and Public Health, Cardiovascular Pathology, University of Padua Medical School, Via A. Gabelli, 61, 35121 Padua, Italy.

The aorta is not a rigid tube, it is an "organ" with lamellar units, consisting of elastic fibers, extracellular matrix and smooth muscle cells in between as parenchyma. Several diseases may occur in the natural history of the aorta, requiring replacement of both semilunar cusps and ascending aorta. They may be congenital defects, such as bicuspid aortic valve and isthmal coarctation with aortopathy; genetically determined, such as Marfan and William syndromes; degenerative diseases, such as atherosclerosis and medial necrosis with aortic dilatation, valve incompetence and dissecting aneurysm; inflammatory diseases such as Takayasu arteritis, syphilis, giant cell and IgM4 aortitis; neoplasms; and trauma.
