“…Although myxoma is the most common benign cardiac tumor usually arising from around the fossa ovalis [Rao 2016], the mass originating from the RVOT and extending across the pulmonary valve into the pulmonary artery is extremely rare with only 6 previously reported myxoma cases to our knowledge [Skillington 1987;Mukadam 1994;Kumagai 2008;Tempe 2010;Ivanovic 2010;Katiyar 2020]. Echocardiography and CT are widely used to diagnose myxoma, however, it is not easy to discriminate myxoma from thrombus or others because the tumor includes a central thrombotic component, avoiding enhancement in CT and letting us recognize as an intracardiac thrombus [Katiyar 2020].…”

Right ventricular myxoma is very rare, especially its originating from the right ventricular outflow tract (RVOT) and extending to the main pulmonary artery. Here, we report a case of a giant RVOT myxoma, indistinguishable from pulmonary embolism (PE). Although the myxoma is a candidate for urgent surgery, this case satisfied diagnostic criteria for PE and had no indication for intervention, according to the guideline. The strategy for this mass can be completely different, depending on the diagnosis. Surgical extraction was selected because of atypical clinical course, findings, and nagging debut for neoplasm. Then it made hemodynamic status stable by releasing RVOT obstruction and allowed to reveal the diagnosis as myxoma histopathologically.

“…These patients may present with systemic embolization (cerebral or peripheral) or with symptoms due to intracardiac obstruction [8]. In current practice, myxomas are often discovered in asymptomatic patients, which can be easily missed and lead to delayed diagnosis.…”

BackgroundCardiac myxoma is the most common primary cardiac tumor. Approximately 75–80% of myxomas are located in the left atrium. Occurrence of multiple myxomas is extremely rare.Case presentationWe describe a rare case of biventricular myxomas resulting in right ventricular inflow and tricuspid valve obstruction. The lesions were detected by echocardiography and thoracic computerized tomography (CT) and confirmed on positron emission tomography–computed tomography.ConclusionThe patient underwent successful surgical resection of the multiple cardiac myxomas. This kind of biventricular case has not been previously reported. The patient is asymptomatic as of the 10-month follow-up.
