Background: Secondary cardiac tumors are far more frequent than primary tumors. Cardiac metastasis of osteosarcoma is extremely rare. Case Presentation: We report a 14-year-old child with left femur osteosarcoma that had metastasized to the left ventricle after 30 months of follow-up. The diagnosis was confirmed based on the findings of transthoracic echocardiography and fluorodeoxyglucose positron emission tomography/computed tomography. Surgical removal was indicated in the patient, but his parents refused this decision, and the patient was discharged and admitted to a pediatric oncology center for chemotherapy. The patient died after four courses of chemotherapy. Conclusion: Cardiac metastasis of osteosarcoma is a strong predictor of disease. The demographic differences shown in our case include male sex and a short interval between onset and cardiac involvement.

Background: Bilateral Internal Carotid Artery Occlusion (BICAO) is an extremely rare pathological entity which have grave prognosis. It is responsible for 0.4% of completed strokes. Asymptomatic BICAO remains exceptional. Case report: We present a case of a 72-year-old man with asymptomatic bilateral internal carotid artery occlusion associated with stenosis of the right external carotid artery. Discussion: Therapeutic abstention was indicated given the absence of symptoms and the advanced age of our patient. Due to the limited cases reported in the literature whose therapeutic outcomes are controversial, the proper management strategy of BICAO remains unclear. Conclusion: We concluded that the increase in the number of reported cases, preferably series with large sample, as well as a long-term follow up for these patients will allow for a better evaluation of each therapeutic decision select.
