A 14 year old boy is presented who was admitted to the psychiatric ward because of delirium. He also had gynaecomastia, facial oedema, striae, and hypertension. He was finally proved to have a mixed oestrogen and cortisol producing adrenal tumour which was removed surgically with complete improvement and no relapse. 相似文献

T1 and T2 measurements on a 1.5-T commercial MR imager 总被引:1,自引:0,他引:1
In order for relaxation times to be used in clinical diagnosis, the precision of the measurement must be determined. The authors measured T1, T2, and proton density in a phantom and in human volunteers to determine the reproducibility of the method. The coefficient of variance of T1 measurements in the phantom during a 15-month period with two software upgrades was 5%. Variance of T2 measurements with any given software was 4% or less, and overall in the 15-month period, with two software changes, the T2 reproducibility was between 6% and 9%. The reproducibility is sufficiently high that precise clinical measurements of T1, T2, and proton density are feasible. 相似文献

INTRODUCTION: Breast cancer with metastatic sentinel lymph nodes (SLN) may have clinico-pathologic factors associated with the presence of positive non-sentinel axillary nodes (NSLN). The aim of the present study was to determine factors that predict involvement of NSLN in breast cancer patients with positive SLN. MATERIAL AND METHODS: A prospective database search identified 80 patients who underwent SLN biopsy for invasive breast cancer between January 1999 and August 2002. Clinico-pathologic data was analyzed to determine factors that predicted additional positive axillary nodes. RESULTS: A total of 23 patients had positive SLN and underwent conventional axillary lymph node dissection. Statistical analysis revealed that lympho-vascular invasion (p~0.00000), SLN metastasis >2 mm (p=0.002), and the presence of extra-nodal involvement (p=0.002), were positive predictors of the metastatic involvement of NSLN. CONCLUSIONS: The likelihood of positive NSLN correlates with pathologic parameters such as the presence of lympho-vascular invasion, size of the SLN metastasis, and extra-nodal involvement. These data may be helpful with the regard to the decision to undertake axillary dissection in breast cancer patients with metastatic sentinel lymph nodes. 相似文献
