一位66岁的男性因呼吸困难入院。胸部X光片和胸部计算机断层扫描(CT)显示左侧胸腔积液和多发肿瘤，提示左侧胸膜间隙有恶性间皮瘤，但没有肺部病变。然而，腹部CT显示右肾肿瘤。超声引导下胸膜肿块的针吸活检提供了转移性肾细胞癌的证据。在右肾根治术和随后的干扰素-a治疗后，胸膜病变显著缩小。虽然胸腔是肾癌的常见受累部位，但单发胸膜转移很少见，而且常常继发于肺部受累。巴特森氏丛是一个由多个连接的无瓣膜的椎静脉组成的网络，可能是肾细胞癌对侧胸膜转移的原因。
A 66-year-old man was admitted with dyspnoea. Chest X-ray and chest computed tomography (CT) demonstrated a left-sided pleural effusion and multiple tumours, suggesting malignant mesothelioma in the left pleural space, but there were no pulmonary lesions. However, abdominal CT revealed a right renal tumour. An ultrasonography-guided needle biopsy of the pleural mass provided evidence of metastatic renal cell carcinoma (RCC). The pleural lesions dramatically decreased in size following right radical nephrectomy and subsequent interferon-a treatment. While the thorax is a frequently affected site of RCC, sole pleural metastases are rare and are often secondary to lung involvement. Batson's plexus, a network of vertebral valve-less veins with multiple connections, is likely responsible for the contralateral pleural metastases of RCC.
