Multimodality Imaging in the Evaluation of Cardiovascular Manifestations of Malignancy
Figure 2
Fibroma. An ovoid mass partially obstructs the right ventricular outflow tract ((a)–(f), asterisk). The mass is of intermediate intensity on T1-weighted imaging ((a) and (b)) and low signal on T2-weighted imaging (c). This combination of findings would make malignancy relatively unlikely since many neoplasms have a relatively high water content and thus are high signal on T2 sequences. Dramatic contrast uptake is, however, evident on the postgadolinium images ((e) and (f)). Dense fibrous tumors may behave in this way, and the diagnosis of fibroma was later confirmed.
