Large Lymphoma Involving the Aortic Arch and its Branches: Demonstration by Echocardiography and Contribution to the Assessment of Hemodynamic Repercussions
DOI: 10.47593/2675-312X/20213402eabc138
An 18-year-old man reported cervical adenomegaly that had progressively increased for about one year. The tumor was visible, was non-mobile, had a fibroelastic consistency, was painless on palpation, and showed no signs of inflammation. He was diagnosed with classical Hodgkin’s lymphoma by a lesion biopsy with anatomopathological and immunohistochemical tests (CD15-, CD30-, and PAX-5-antibody–positive). Transthoracic echocardiography showed a large mass with a heterogeneous texture involving the pulmonary artery, the aortic arch (and its main branches), and the proximal descending aorta. Pulse and continuous wave color Doppler showed no evidence of flow impairment in the proximal descending aorta or the proximal segments of the brachiocephalic trunk, left common carotid artery, and left subclavian artery. Contrast chest tomography corroborated the echocardiographic findings, showing an extensive solid mediastinal tumor looking resembling a lymph node conglomerate occupying the anterior and middle compartments of the mediastinum and involving the vascular structures. There were no signs of compression or invasion.
