Wilms tumor, the most common solid childhood malignancy, is frequently associated with pulmonary metastases, while hepatic metastases occur less frequently. Metastases to the lower lobes of the lungs, when deep in the costophrenic sulcus, may simulate an intraabdominal mass. The differentiation of these lesions is important both diagnostically and therapeutically. Three cases are presented in whom pulmonary sulcus metastases simulated abdominal lesions on computed tomography and could not be clearly localized as thoracic in origin on liver/spleen scintigraphy. Ultrasound evaluation was the most useful; however, integration with other imaging techniques was necessary to correctly identify these lesions as being of pulmonary origin.
肾母细胞瘤是儿童最常见的实体恶性肿瘤，常伴有肺转移，而肝转移相对少见。肺下叶转移灶若位于肋膈沟深处，可能类似腹内肿块。这些病变的鉴别在诊断和治疗上都很重要。本文报告3例，其肺沟转移灶在计算机断层扫描上类似腹部病变，在肝/脾闪烁扫描上无法明确定位为胸部起源。超声评估最为有用；然而，需要与其他影像学技术相结合才能正确识别这些病变为肺源性。
