Atypical imaging presentation of a massive intracavitary cardiac thrombus: A case report and brief review of the literature

Abstract

Intracavitary cardiac thrombi, uncommonly found in the right chambers, have been shown to form secondary to endocardial and myocardial diseases. The differential diagnosis for an intracavitary cardiac mass is broad, including primary cardiac tumors, cardiac metastases, anatomic variants, vegetations, and thrombi. Here we present a unique case with a large calcified intracavitary cardiac thrombus in a 26-year-old woman with obesity, immune thrombocytopenic purpura, and a new diagnosis of systemic lupus erythematosus. Initial imaging presentation in this case masqueraded as a tumor, delaying the true diagnosis. A combination of cardiac imaging techniques, including transthoracic and transesophageal echocardiograms, cardiac CT, and cardiac MRI were required to correctly diagnose this calcified bland thrombus.

Computational Analysis of the Related Factors of Deep Vein Thrombosis (DVT) Formation in Patients Undergoing Hip Fracture Surgery

“…The INARI FlowTriever device can remove DVT and significantly reduce the risk of bleeding [ 14 ]. Some studies analyzed and studied the causes of DVT and the locations where DVT frequently occurs [ 15 , 16 ]. Other studies have found that DVT can trigger other diseases [ 2 , 17 – 19 ], such as multiple organ embolism, stroke, and acute myocardial infarction.…”

Prominent crista terminalis mimicking a right atrial mass: A case report and brief review of the literature

“…The improved spatial and temporal resolution of imaging modalities have led to increased detection of normal anatomical variants and structures, which may lead to misdiagnosis. Hence, a comprehensive understanding of normal anatomical variants, and its characteristic appearance on transthoracic echocardiogram, CT and PET/CT is essential [ 1 , 3 , [9] , [10] , [11] , [12] , [13] , [14] ].…”

“…Hence, normal variants are typically distinguished from masses based on their location and ancillary features (including: attenuation values, contrast enhancement and local invasion). Delayed phase (45–60 seconds) can help in differentiating intracavitary thrombus from normal variants [ 9 , 15 , 16 , 19 , 20 ]. Thrombus would remain low attenuating, whereas normal variants will show contrast enhancement similar to adjacent myocardium [ 1 , 3 , 9 ].…”

Giant mediastinal bronchial artery aneurysm mimicking mediastinal mass: A case report and brief review of the literature

“…Pathology in the mediastinum typically originate from lymph nodes, thymus, thyroid, esophagus, neurogenic, vascular and germ cell tumor [20] . Rare etiology would include amyloidosis or cardiac mass extending into the mediastinum [21] , [22] , [23] , [24] . Intrapulmonary bronchial artery aneurysm presents with hemoptysis when ruptured into the trachea or airways.…”
