Results of ultrasound guided percutaneous fine-needle puncture cytology in 142 cases of malignant tumors of the liver are reported. The positive cytology was noted in 118 (83.1%) (10 suspicious). The primary liver cancer comprised 99 cases. In 7 lesions, equal to or less than 3 cm in diameters, 6 were positive in cytology. In 20,3-5 cm in size, 18 were positive. In 15 false-negatives, 12 were larger than 5 cm in diameter. Among 43 cases of metastatic liver cancer, 34 showed positive cytology and 9 false-negative. Among 108 cases of benign hepatic diseases, in 49.1%, it was difficult to arrive at definitive diagnosis by ultrasonography only, but in 97.2% malignancy was excluded by ultrasound guided fine-needle puncture cytology. The suspicious false-positive result occurred only in 3 cases. In this series, there were 250 cases of malignant tumors and benign diseases. The overall accurate diagnostic rate was 89.2%. All the patients had been followed for more than 6 months. The differential diagnosis between malignant and benign tumors, causes of misdiagnosis and complications are discussed.
报告了142例肝脏恶性肿瘤的超声引导下经皮细针穿刺细胞学检查结果。细胞学阳性118例（83.1%）（10例可疑）。原发性肝癌99例。直径小于或等于3cm的病灶7个，细胞学阳性6个。大小为3 - 5cm的病灶20个，阳性18个。15例假阴性中，12个直径大于5cm。43例转移性肝癌中，34例细胞学阳性，9例假阴性。108例良性肝病中，仅靠超声检查难以明确诊断的占49.1%，但超声引导下细针穿刺细胞学检查排除恶性病变的占97.2%。可疑假阳性结果仅3例。本系列共250例恶性肿瘤和良性疾病。总体准确诊断率为89.2%。所有患者均随访6个月以上。讨论了恶性与良性肿瘤的鉴别诊断、误诊原因及并发症。
