目的 探讨病毒性脑炎的核磁共振成像(magnetic resonance imaging,MRI)、扩散加权成像(diffusion weighted imaging,DWI)和质子MR波谱(1H magnetic resonance spectroscopy,1H-MRS)表现. 方法 36例病毒性脑炎在急性或亚急性阶段接受了常规MRI、DWI及2D 1H-MRS检查.总结病毒性脑炎常规MRI、DWI及 1H-MRS表现特点,比较病毒性脑炎和对侧正常脑组织的表观弥散系数值(ADC)、胆碱(Cho)、N-乙酰天门冬氨酸(NAA)、肌酸(Cr)差异有无统汁学意义.结果病灶表现多发22例,单发14例,可累及皮层、皮层下、侧脑室周围白质以及基底节-丘脑区.T1WI呈稍低信号,T2WI呈高信号,可有轻度斑片状强化.DWI上呈等或稍高信号11例,均匀高信号4例,不均匀高信号21例.ADC伪彩图上26例扩散加快,另外10例扩散加快与受限同时存在.病毒性脑炎ADC值[(0.93±0.29)×10-3 mm2/s]较对侧腑白质[(0.76±0.32)×10-3mm2/s]升高,差异有统计学意义(P=0.007).病毒性脑炎的Cho、Cr和NAA分别为(364.3±56.3)、(178.4±28.2)、(203.7±33.8),较对侧[分别为(440.2±52.8)、(269.3 ±37.5)、(386.5±68.5)]相应波峰降低,差异有统计学意义(P<0.01,P<0.05),有3例见Lac峰. 结论 DWI、1H-MRS反映了病毒性脑炎的组织及代谢特点,是常规MRI有益的补充. 相似文献

目的:探讨小儿癫痫的临床特点及治疗。方法:对经临床及脑电图诊断为癫痫的54例患儿进行临床观察,并根据发作类型选药;采用丙戊酸钠(VPA)或卡马西平(CBZ)单药治疗,并监测药物浓度及随访脑电图(EEG)。结果:临床表现为全身性发作37例,局灶性发作17例。37例单用VPA治疗,6个月后发作获完全控制,VPA平均血药浓度89.2mg/L;17例单用CBZ治疗,6个月后获完全控制,CBZ平均血药浓度6.37mg/L。治疗前EEG异常52例,治疗后恢复34例。结论:小儿癫痫的发作形式多种多样,具有反复发作、暂时性的特点。丙戊酸钠或卡马西平单药治疗小儿癫痫具有良好的疗效,血药浓度监测对治疗有指导作用,脑电图不能作为判定疗效的唯一指标。 相似文献

Four cases of sinonasal and nasopharyngeal adenoidcystic carcinoma that came to the RIMS Hospital, Imphal during the period of July, 2002 to March, 2003 are reported in this article. The age incidence ranged from 30 to 80 years and the mean age was 47.5 years; with male to female ratio of 1:1. The average duration from first sympton in the patient to the date of his medical consultation was 17.8 months. Nasal obstruction was the first symptom two cases; lump sensation in the throat and headache in the third and fourth cases respectively. Despite the evidence of rapid and extensive local spread there were definitely delays from the patients' end to consult a clinician. Whereas the tumour itself is not common, the usual sites, if it occurs, are palate and minor salivary glands and rarely mucous and seromucinous glands elsewhere. 相似文献

目的: 探讨脑囊尾蚴病的临床及磁共振(MRI)特点。方法: 对81例脑囊尾蚴病患者的临床资料和头颅MRI进行回顾性分析。结果: 81例脑囊尾蚴病头颅MRI表现分为脑实质型73例、脑室型5例和混合型3例;活虫期、退变死亡期、非活动期及混杂期四期,以脑实质型和退变死亡期最常见。杀虫治疗一般需要3~5个疗程。结论: 头颅MRI可以对脑囊尾蚴病进行准确分型、分期,为用药及疗程的确定提供依据,还可用于CT检查阴性的脑囊尾蚴病的确诊。 相似文献

Pulmonary infections mimicking cancer: report of four cases 总被引:3,自引:0,他引:3
Lung infections infrequently simulate cancer, and their differentiation, based on imaging findings, can sometimes be difficult. The infections may be fungal, mycobacterial, parasitic or, rarely, viral. A biopsy is required to prove the infectious nature of the lesions. A specific diagnosis is necessary for initiation of appropriate therapy. We report four cases of chronic pulmonary infections, which were wrongly diagnosed as bronchogenic carcinoma based on radiological features. We also reviewed the existing literature. 相似文献

Pulmonary alveolar microlithiasis (PAM) is a rare disease. There have been only about 400 cases reported internationally since it was first described by Feidirch in 1856 PAM has familial tendency, but there are few reports of four cases in one family. 相似文献

Establishing a diagnosis of syphilis, whatever the stage of the disease, can be difficult because syphilis is a great mimic in clinical morphology and histology. Many patients infected with venereal diseases have oral manifestations, but very few dentists and physicians have the proper experience to diagnose syphilis or other STDs from oral lesions. Oral secondary syphilis appears to be very uncommon, and few cases have been reported over the recent past. We present 4 patients who developed secondary syphilis-related oral lesions of moist ulcers, irregular linear erosions termed 'snail-track' ulcers, or erythematous mucous patches on the labial mucosa, buccal mucosa, palate, or tongue. Concurrent human immunodeficiency virus (HIV) infection was diagnosed in 1 patient. The histological examination in 2 patients showed dense subepithelial inflammatory cell infiltration comprised predominantly of plasma cells, and it was of practical help in the diagnosis of syphilis. The diagnostic value of a histological examination, serologic tests, and treatment of syphilis are discussed. Obviously, coinfection with HIV will complicate the clinical presentation, diagnosis, and management of syphilis. Concurrent HIV infection should be considered in any patient with a sexually transmitted disease including syphilis. 相似文献

Myxoid adrenocortical neoplasms are rare. Surgical resection of the mass is the first-line therapy. Here we reported a total of four patients, aged 44–66 years, diagnosed with myxoid adrenocortical tumor. The clinical characteristics and immunohistochemical features of the tumor are discussed in the current literature.

Superficial cervicovaginal myofibroblastoma: report of four cases and literature review 总被引:1,自引:0,他引:1
In 2001, Laskin et al firstly described a series of 14 seemly distinctive mesenchymal tumors that occurred exclusively in the superficial lamina propria of the vagina and cervix of middle to old-aged women. They proposed the term "superficial cervicovaginal myofibroblastoma (SCVM)" to highlight the unique features of this tumor: the superficial subepithelial location and myofibroblastic differentiation of the minor cells. SCVM appears less well recognized with only three additional reports have been documented in the English literatures.24 In this study, we described four new cases of SCVM to further characterize the clinical and pathological features of this rare entity. 相似文献
