Retroperitoneal teratomas are rare in adults; they are malignant in 25.8% of cases. The authors report two benign cases in which radiologic examination was essential in establishing the diagnosis. Irregular calcifications, which are visible in 61.5% of reported cases, cannot be considered a sign of benignity, since 12.5% of calcified tumors were malignant. Because of the indeterminate course of the disease, surgical removal is indispensable.
腹膜后畸胎瘤在成人中罕见；25.8%的病例为恶性。作者报告了两例良性病例，其中放射学检查对确诊至关重要。在61.5%的报告病例中可见不规则钙化，但不能将其视为良性的标志，因为12.5%的钙化肿瘤为恶性。由于疾病进程不确定，手术切除必不可少。
