Four patients with islet cell tumours were explored with selective angiography. The radiological findings of 3 insulinomas and 1 nonfunctioning tumor are described. The typical hypervascular pattern of parenchimatose phase was found in all. The three insulinomas were successfully treated surgically. The nonfunctioning tumor was not removed due to the pathologists original impression that it was a maligant tumor involving the portal vein. Angiographic pattern, etiology, differential diagnosis and causes of errors are discussed. The method is diagnostically useful and offers important precperative information thus reducing operating time and minimizing the magnitude of the surgery.
对4例胰岛细胞瘤患者进行了选择性血管造影检查。描述了3例胰岛素瘤和1例无功能性肿瘤的放射学表现。所有病例均发现了典型的实质期血管丰富模式。3例胰岛素瘤均成功接受了手术治疗。由于病理学家最初认为该无功能性肿瘤是累及门静脉的恶性肿瘤，因此未予切除。讨论了血管造影模式、病因、鉴别诊断及误诊原因。该方法具有诊断价值，并能提供重要的术前信息，从而缩短手术时间并使手术范围最小化。
