Four patients (2 males, 2 females; ages 15-47 yrs.) with variable clinical, radiographic, and scintigraphic manifestations of progressive diaphyseal dysplasia (PDD) or Engelmann disease were studied with 99mTc methylene diphosphonate bone imaging and radiographic skeletal surveys. Comparison of the results of the two imaging procedures showed that some affected bones were scintigraphically normal but radiographically abnormal and vice versa. These findings suggest that the lesions of PDD may mature, causing a significant decrease in disease activity, and that abnormally increased radiopharmaceutical accumulation during bone scintigraphy appears to be a sensitive indicator of disease activity.  相似文献

目的:通过本研究建立中国婴儿正常脑髓鞘化的时间表。材料与方法:选100例2岁以内的没有神经系统疾病的小儿,按月龄分成5组,用0.35TMR仪在T1加权像(T1WI)和T2加权像(T2WI)上分别观察髓鞘形成的进程及在T2WI上对灰白质分辨进行分期。结果:(1)灰白质分辨分为5期,新生儿100%属Ⅰ期,6个月内的婴儿88%为Ⅱ期,6个月以上的婴儿20%为Ⅲ期、80%为Ⅳ期,14个月时达Ⅴ期,18个月时接近成人。(2)髓鞘化时间,后颅窝结构3~4个月时即达成人早期,内囊后肢在6个月内、前肢在7~10个月,胼胝体压部是4个月、膝部是6个月,顶枕叶10个月,额叶12个月,颞叶15~18个月,皮层下的白质持续到2岁以后。结论:脑灰白质分辨的5期,反映了脑发育的过程,与月龄关系密切,对判断脑发育是否落后非常重要  相似文献

A radiological study of 85 patients with acute pericarditis and effusion included a group of 35 cases observed before the introduction of ultrasonography and a second group of 50 patients in whom the presence of pericarditis had been confirmed by this investigation. The most important conclusions established were the following: --Absence of radiological signs in 55% of cases (group 1 : 46%, group 2 : 60%); normal heart size in 54% (group 1) and 78% (group 2), and increased size in 34% (group 1) and 20% (group 2). --Hilar manifestations (overlapping and obscuring of the left hilar region) in 26% of cases with a clear predominence of the left forms (14 out of 22). The cardiomegaly was not significant in 28% (group 1) and 14% (group 2). --The high frequency of pericarditis with a normal heart size has to be emphasized. The diagnostic value of hilar manifestations is also mentioned; the sign of left hilar overlapping is described in greater detail. --An overall comparison between the two groups shows, more particularly, the equal importance of left hilar manifestations for the radiological diagnosis of pericarditis. In a general way, it would appear that these hilar signs are the only elements which enable objective diagnosis of pericardial effusions on standard films.  相似文献

Lymphangioleiomyomatosis (LAM) is a rare disease that usually affects premenopausal woman and is characterized by cystic lung lesions and lymphatic disorders. We report a case of a 23-year-old woman who presented with diffuse, but increasing abdominal pain. Transabdominal ultrasound showed multiple cystic formations. Due to the patient’s uncharacteristic symptoms, an exploratory laparotomy with tissue sampling was performed, and the diagnosis of LAM was confirmed by two independent pathologists. With computed tomography a broad abdominal, but no pulmonary, manifestation could be established. During sirolimus therapy the patient showed clinical benefit, but only slight progress in computed tomography.  相似文献
