Giant right atrial myxoma emerging from the suprahepatic inferior vena cava, extending to the right atrium; a case report and literature review

Atrial myxomas are the most common primary cardiac tumors. In 20% of cases, they arise from the right atrium. Only a few such tumors are reported to have arisen from the inferior vena cava. We present the case of a 20-year-old female with recurrent vomiting and supraventricular tachycardia (SVT), found to have a massive myxoma emerging from the suprahepatic Inferior vena cava (IVC) involving the eustachian valve, and extending to the right atrium. Surgical excision was successful, leading to an uneventful recovery. This case underscores the importance of prompt diagnosis and surgical intervention in managing right atrial myxomas to prevent potential complications such as embolism and sudden death.
