Primary cardiac osteosarcomas are uncommon tumors. They have an aggressive biology and hence poor prognosis. This report describes a 23-year-old male patient who was referred to our hospital with chest pain. Echocardiography showed a left atrial mass, and tumor excision revealed a cardiac osteosarcoma. Adjuvant cisplatin plus ifosfamide combination chemotherapy provided a disease-free survival of 9 months; unfortunately the patient died of metastatic disease thereafter.

Here we report, for the first time, a combination of five-vessel aortic arch, anomalous origin of the right vertebral artery (VA) from the common carotid artery (CCA), an aberrant right subclavian artery (SCA), and bilateral symmetrical segmental agenesis of VAs.In this case report, we present a patient with moyamoya syndrome (MMS) and Down syndrome (DS) who has bilateral symmetrical segmental agenesis of VAs, left VA originating from aortic arch and anomalous origin of right VA arising from CCA in combination with an aberrant right SCA. Therefore, five vessels are originating from aortic arch. Here, we report, for the first time, a combination of five-vessel aortic arch with an aberrant right SCA and symmetrical segmental agenesis of both VAs. The possible embryological mechanisms of the anomalies as well as an relation with MMS and DS are discussed.
