Eight patients with sciatic nerve and sacral plexus nerve sheath tumors, seen at Louisiana State University Medical Center in Shreveport, are presented. These cases illustrate the broad spectrum of pathology and modes of presentation of patients with nerve sheath tumors in this region. Patients can be divided into 4 groups. Group I includes subgluteal and/or thigh lesions with a well-defined mass on CT. Group II patients have neuroforaminal enlargement (defined by CT) and usually have radicular leg pain. Patients in group III have intrapelvic tumors with extension into the thigh. They usually have a poorly defined mass on CT. Group IV includes patients that have an intrapelvic mass (usually well defined) with radicular leg pain and/or mass effect. CT scanning proved to be the diagnostic procedure of choice. It delineated the location and extent of the tumor and thus was important in determining resectability. The variable course of these tumors is emphasized. A conservative nonoperative approach should be considered in asymptomatic and/or neurologically stable patients.
本文介绍了在什里夫波特的路易斯安那州立大学医学中心就诊的8例坐骨神经和骶丛神经鞘瘤患者。这些病例说明了该区域神经鞘瘤患者的广泛病理类型和表现方式。患者可分为4组。第一组包括臀下和/或大腿部病变，CT显示肿块边界清晰。第二组患者有神经孔扩大（由CT定义），通常有腿部放射性疼痛。第三组患者有盆腔内肿瘤并延伸至大腿，CT上肿块通常边界不清。第四组包括有盆腔内肿块（通常边界清晰）并伴有腿部放射性疼痛和/或肿块效应的患者。CT扫描被证明是首选的诊断方法，它能描绘肿瘤的位置和范围，因此对确定肿瘤的可切除性很重要。强调了这些肿瘤的不同病程。对于无症状和/或神经功能稳定的患者，应考虑采取保守的非手术方法。
