From: Metastasis of osteosarcoma to the trapezius muscle: a case report
CT and MRI imaging of metastatic osteosarcoma. (a) Computational tomography (CT) imaging of lung metastasis in the early course of the disease. Multiple metastases are seen in both lungs. Axial (b) T1-weighted and (c) T2-weighted magnetic resonance imaging (MRI) scan shows a heterogeneous, ill-defined mass measuring 73 × 45 × 60 mm in the right trapezius muscle. (d) Gadolinium-enhanced T1-weighted image shows a circumscribed signal abnormality in the right trapezius muscle that was moderately enhanced.
