Multiple myeloma with cardiac involvement accompanied by partial
superior vena cava obstruction: a case report and literature review
Abstract
Extramedullary involvement of the endocardium is rare in multiple
myeloma. Here we describe a case of multiple myeloma (plasma cell) with
extramedullary plasmablastic transformation and endocardial involvement,
which resulted in partial superior vena cava obstruction. We also
conducted a literature review and summary analysis of space-occupying
lesions in the heart in 12 patients with multiple myeloma (including the
current case) in the last 10 years. Echocardiography is the preferred
radiologic examination method for diagnosis and follow-up in multiple
myeloma, and surgical resection is effective for alleviating symptoms.
