【摘要】目的:分析骶骨肿瘤的类型分布及临床特点。方法:1998年7月~2009年6月,我院骨肿瘤中心诊治
445例骶骨肿瘤患者,男228例,女217例。年龄5~83岁,平均46.4岁。352例患者就诊时有严重腰骶部和/或下
肢疼痛,93例患者因发现局部包块就诊。所有患者均有术后病理诊断。回顾分析所有患者的临床和影像学资料。结果:原发骶骨肿瘤351例,男174例,女177例,平均年龄44.4岁。其中脊索瘤95例,男62例,女33例,平均年龄55.7岁,骶尾区疼痛是主要症状(82例),半数以上患者伴有坐骨神经痛,肿瘤多先累及低位骶骨(S3~S5);神经源性肿瘤76例,男36例,女40例,平均年龄47.7岁,神经纤维瘤43例,神经鞘瘤24例,恶性神经鞘瘤9例,主诉多为坐骨神经痛、会阴部麻木(36例)和无痛性包块(11例),20例患者为查体或其他原因检查时发现,67例骶骨良性神经源性肿瘤起源于S3以上神经者54例,起源于S3以下神经者3例,发生于骶前未累及骶管者10例;骨巨细胞瘤60例,男24例,女36例,平均年龄32岁,腰骶尾部不适(37例)、坐骨神经痛(21例)是主要的临床表现,肿瘤多先累及上位骶骨(S1~S2);骶骨其他原发良性肿瘤及瘤样病变56例,包括畸胎瘤、皮样囊肿、表皮样囊肿共24例;其他原发恶性肿瘤64例,包括软骨肉瘤17例,尤文肉瘤14例,多发性骨髓瘤12例,成骨肉瘤6例等。转移性骶骨肿瘤94例,男54例,女40例,平均年龄54.1岁,包括不明来源转移瘤23例,肺癌转移13例,肾癌转移12例,大肠癌转移10例等。结论:脊索瘤、神经源性肿瘤和骨巨细胞瘤是骶骨常见的三大肿瘤,占骶骨原发肿瘤的2/3。对于出现腰骶部疼痛、下肢疼痛的患者,应警惕骶骨肿瘤的可能。根据患者年龄、病灶部位及影像学表现,可以作出相对正确的初步诊断。【关键词】骶骨;肿瘤;类型;诊断
