髋关节一过性骨髓水肿综合症的临床和MRI表现

目的:探讨髋关节一过性骨髓水肿综合症的临床特征和MRI表现,旨在提高对本病的认识.方法:回顾性分析我院经临床或随访证实的11例一过性骨髓水肿综合症患者的MRI图像和临床特点;临床措施主要是对症治疗及嘱咐患者减轻负重并按时随访:随访时间为3～6个月.结果:11例一过性骨髓水肿综合症患者男8例,女3例,双侧髋关节同时受累1例,单侧髋关节受累10例,其中右侧4例,左侧6例;病变累及股骨头2例,累及股骨头、颈和股骨粗隆9例;关节腔少量积液5例;初次MRI扫描病变区域骨髓在T1WI为低信号11例;T2WI为高或略高信号9例,等信号2例;T2WI脂肪抑制(STIR)均为高信号;急性期关节腔可伴有少量积液呈长T1、长T2信号改变5例;3个月后复查.患者病变区域骨髓异常信号完全消失2例,大部分消失8例,1例病变范围部分缩小,5例关节腔少量积液均已吸收;6个月后复查9例患者症状完全消失,病变区域骨髓信号正常.结论:MRI对髋关节一过性骨髓水肿综合症的诊断及鉴别诊断有重要价值.

髋关节一过性骨髓水肿综合症的临床特征和MRI表现与鉴别分析

目的分析髋关节一过性骨髓水肿综合症(TBMES)的临床特征及MRI表现。方法回顾性分析经磁共振成像(MRI)检查、随访证实的15例TBMES患者相关资料,观察TBMES临床特征及MRI表现。结果临床特征:所有患者患侧腹股沟区压痛,活动受限;实验室检查类风湿因子、血尿常规检查均正常;15例中单侧髋关节受累13例;累及股骨头、颈、股骨粗隆间12例;关节腔内积液7例。MRI对TBMES检出率明显高于X线片,差异有统计学意义(P<0.05)。股骨近端病变MRI上显示T1WI低信号,T2WI高或略高信号为主(12例),T2WI-STIR高信号;MRI显示关节腔内积液为长T1、长T2信号;MRI显示患侧髋关节周围肌肉层次清楚,无异常信号。随访6个月症状消失,MRI复查无复发。结论 TBMES典型特征为髋部疼痛,MRI诊断TBMES敏感度明显高于X线片,正确掌握TBMES主要征象有利于其诊断及鉴别。

SPIROCHETES—— THE POSSIBLE ETIOLOGICAL FACTOR OF THE CHEILITIS GRANULOMATOSA

To detect spirochetes in sections and to study the therapeutic effect of penicillin in cheilitis granulomatosa (CG) and Melkersson- Rosenthal syndrome (MRS) and the relationship between the spirochetes infection and CG and MRS. Methods. Routine HE sections and Warthin- Starry special staining were carried out in 20 cases of CG and 6 cases of MRS. Meanwhile there were 9 cases of CG and 2 cases of MRS were treated by penicillin (12 000 000u,IV, per day) for two courses (14 days). Results. A kind of spirochete was discovered in the sections of all cases of the CG and MRS .The CG and MRS could be divided into two types histopathologically, that is granuloma type and interstitial inflammatory type (non- granuloma type), those morphological changes tallied with spirochetosis. After treatment by penicillin, the facial and labial swelling of the 11 cases of CG and MRS were abated. Conclusion. CG and MRS probably are infectious diseases caused by spirochetes.
