Sciatic and lower extremity neurologic symptoms may be from pathologic involvement of the sacral plexus or sciatic nerve in the region of the greater sciatic foramen. Twenty-five patients were reviewed who presented consecutively over a 4 year period with sciatic symptoms secondary to pathologic changes in the greater sciatic foramen. Malignant neoplasm alone (18 patients) and malignant neoplasm associated with infection (two patients) account for most of these cases. Neurogenic tumors (three patients), both benign and malignant, and infection alone (three patients) were less frequent. Although sciatic symptoms usually derive from spinal abnormalities, the evaluation of sciatic symptoms should not be considered complete without CT scanning of the greater sciatic foramen.
坐骨神经及下肢神经症状可能源于坐骨大孔区域的骶丛或坐骨神经的病理累及。回顾了连续4年出现因坐骨大孔病理改变继发坐骨神经症状的25例患者。其中大多数病例为单纯恶性肿瘤（18例）和伴有感染的恶性肿瘤（2例）。神经源性肿瘤（3例，包括良性和恶性）及单纯感染（3例）则较少见。虽然坐骨神经症状通常源于脊柱异常，但如果未对坐骨大孔进行CT扫描，对坐骨神经症状的评估不应被认为是完整的。
