Tricuspid valve metastasis in osteosarcoma, paving way through iliofemoral vessels – An unusual presentation of a usual diagnosis

Abstract

Hematogenous spread of osteosarcoma is a common knowledge, with frequent metastases to lungs and bones. Cardiac involvement is rare finding, most of them depicting contiguous cardiac extension through vessels into the right atrium. Tricuspid metastases are rare. We encountered one such rare case of femur osteosarcoma with multiorgan metastasis including systemic veins, cardiac chambers, and tricuspid valve involvement which presented as diagnostic dilemma. Early detection was crucial for further management and prognostication of patient.
