Intratumoral calcification in myxoma and myxosarcoma. A–E The transverse view of selected PET (1), CT (2), and fused PET/CT (3) images revealed five myxomas with none to mildly increased ¹⁸F-FDG uptake (white arrow, SUVmax 2.2–4.7). On the non-contrast CT (A2–E2), the tumor presented punctate calcification (yellow arrow). F1–F3 The transverse view of selected PET, CT, and fused PET/CT images revealed a myxosarcoma with mildly increased ¹⁸F-FDG uptake (white arrowhead, SUVmax 3.5). On the non-contrast CT (F2), the tumor presented nodular calcification (yellow arrowhead)
