| Popis: | Introduction Primary cardiac tumors are a relatively uncommon condition, which may appear both in asymptomatic patients or in a myriad of clinical presentations. Imaging techniques are crucial for its diagnosis, and a multi-modality approach may be useful in the evaluation of this masses. Case description A 57 year-old man with history of hypertension presented in the emergency department with acute pulmonary edema and cardiogenic shock. He was admitted to the coronary care unit, and on bedside echocardiography a mass on the tricuspid valve was observed. Upon clinical improvement, a cardiac CT and cardiac MRI was performed (figure 1). A solid mass with no calcium content and dependent exclusively on the anterior leaflet of the tricuspid valve was seen on CT-scan (fig 1, A and B). Thrombus on the right atrial appendage could also be appreciated. MRI confirmed the presence of a 18x19 mm mass with isointense signal on T1-turbo spin echo black-blood (fig 1, C) and cine steady-state free precession sequences, whereas an hyperintense signal was evident on T2 weighted images (T2-STIR; fig 1 D). In first pass sequences the central core was hypointense and late gadolinium enhancement showed peripheral enhancement with a non captating central core (fig 1, E). The patient underwent surgery and the anatomopathological results showed a tumor constituted by dense connective tissue, scarce cellular content and an avascular matrix of mucopolysaccharides, elastic fibers and fusiform cells consistent with the diagnosis of papillary fibroelastoma. Discussion The imaging characteristics of papillary fibroelastoma are not commonly reported on MRI. We present an unusually large right-sided fibroelastoma with a characteristic distribution of late gadolinium enhancement, which has not been consistently described on a fibroelastoma. Cardiac tumors are rare, and a non-invasive differential diagnosis is always a challenge. A multi-modality approach (echocardiography, cardiac-CT and cardiac MRI) as well as integration of relevant morphological information, including the location of the lesion and tissue characteristics was essential to the orientate the most plausible diagnosis. The distinctive images are presented. Abstract P729 Figure 1. |
