Free-Floating Thrombus of the Aorta: A Rare Complication of COVID-19-Induced Hypercoagulability.

Free-floating thrombus (FFT) of the aorta is a rare condition characterized by a nonadherent portion of thrombus floating within the aortic lumen. Hypercoagulability is a well-known complication of COVID-19 infection, and thromboses related to COVID-19-related hypercoagulability commonly present in the form of venous or arterial thrombosis such as deep vein thrombosis (DVT), pulmonary embolism (PE), ischemic stroke, and myocardial infarction. Unfortunately, FFT associated with COVID-19 infection has been rarely reported in the literature.

Pembrolizumab-Induced Sarcoid-Like Reaction: FDG-PET Scan Interpretation in the Era of Immunotherapy.

Immunotherapy has revolutionized the treatment of malignant melanomas. Immunotherapy is associated with multi-system toxicities, which are referred to as immune-related adverse events (irAEs). Positron emission tomography (PET) with fluorodeoxyglucose (FDG) and CT is the preferred imaging modality to monitor disease progression in melanoma.

"How Long Do I Have?"-Story of a Myeloma Patient.

Despite uncertainty about a patient’s decision to forgo transplantation for multiple myeloma, the choice raised appreciation of the questions that come up in the life of an oncologist: How do you define the “best” treatment? What should drive cancer care, the years in a patient’s life or the life in those years? Did the physician treat the patient, or did the patient teach the physician?

Importance of performing transesophageal echocardiography in acute stroke patients older than fifty.

Background: The purpose of this study was to determine the value of transesophageal echocardiography (TEE) in determining the presence of cardiac manifestations that required anticoagulation in patients presenting with acute stroke.

Methods: Of 626 consecutive stroke patients who underwent TEE, 188 patients with no obvious etiology for stroke were subcategorized according to age. TEE results were analyzed for cardiac findings suggestive of a cause for embolic stroke, including complex atheromas in the arch/ascending aorta, patent foramen ovale (PFO), atrial septal aneurysm (ASA), and intracavitary thrombi.
