P853 Bilateral lower limb ischemia in a healthy young man what if the heart was hiding the etiology

Cardiac myxoma is the most common benign cardiac tumor with diverse nonspecific clinical manifestations; moreover, atrial myxoma embolization to the peripheral vessels is rare. A 24-year-old man presented tothe emergency departement complaining ofpain and coldness of his two lower extremities. The right femoral pulse was normally felt while the pulses of the left lower limb from the femoral down to the posterior and anterior tibial arteries were not felt. Bilateral thrombectomy was performed on emergency basisand a fatty-like mass from the left femoral artery was removed. The histological examination of this mass was suggestive of myxoma.So, transthoracic echocardiography was done and confirmed the diagnosis of myxoma that was seen in the left atrium and measuring about 10X6 cm in its maximal dimensions. Surgical removal of the myxoma was done later and the patient recovered uneventfully. Conclusion Although myxomas are rare, they should be considered in the differential diagnosis of peripheral embolic disease, especially when an embolic event occurs in a young adult without evidence of endocarditis or arrhythmia. Echocardiography is the modality of choice for diagnosis and follow-up of this type of tumors.
