Recurrent Cardiac Sarcoma - Demonstration by Magnetic Resonance Imaging and Echocardiography

原發之心臟黏液肉瘤為罕見惡性腫瘤，其復發之影像學所見於文獻上較少見。四十歲男性因心臟黏液肉瘤開刀後復發，經接受第二次腫瘤切除手術證實；心臟超音波影像可見腫瘤依附左心房後壁，於舒張期阻塞二尖瓣開口突入左心室。二次術後兩次磁共振影像顯示腫瘤於右下肺靜脈入口處及左心房後壁左側再度復發。由於腫瘤之超音波密度及磁振訊號與心臟肌肉相似，因此追蹤檢查變化為較可靠之復發指標。

Primary cardiac myxosarcoma is a rare primary cardiac malignant tumor. Recurrence demonstrated by imaging findings is hardly found on literature. A 40-year-old male with cardiac myxosarcoma had recurrent tumor after first operation and received second operation, which revealed recurrence. Echocardiography demonstrated a mass attached to the posterior left atrial wall protruding into the mitral orifice during diastole. Magnetic resonance imaging was performed 2 weeks after the second operation and revealed recurrent tumors near the orifice of inferior left pulmonary vein and left posterior wall of the left atrium. Because the echogenicity and signal intensity of the tumors are similar to that of myocardium, serial follow-up of changes of thickness of cardiac is a more reliable indicator of recurrence.
