ABSTRACT
Objective: To describe the magnetic resonance imaging [MRI] appearance of central nervous system lymphoma
Methods: We retrospectively reviewed MRI images of 40 patients who had pathologically proven primary central nervous system lymphoma [PCNSL] and received treatment in Binzhou People's Hospital, Shandong, China from January to December in 2014. Location, size and form of tumor was observed and relevant data were recorded for analysis
Results: Foci of 40 cases of PCNSL all located in brain, among which. 18 cases were single [45.0%] and 22 cases were multiple [55.5%]. Of 96 Foci, 84 were supratentorial, 12 were subtentorial. Enhanced MRI scanning showed that, most Foci had significant homogenous enhancement, shaping as multiple nodular or lumpy, and few had ring-enhancement. MRI suggested that, T1 signal of most Foci concentrated on low signal segment and T2 signal gathered on high signal segment, suggesting a significant homogeneous enhancement; moreover, mild and medium edema surrounded the tumor. They were pathologically confirmed as B cell derived non-hodgkin lymphoma. Except one case of Burkitt lymphoma, the others were all diffuse large B cell lymphoma which was observed with diffuse distribution of cancer cells [little cytoplasm, large nucleus, rough perichromatin granule] in same size. Fifteen cases were observed with sleeve-like infiltration of cancer cells around blood vessels. No case was found with hemorrhage, necrosis or calcification
Conclusion: Pathological foundation of PCNSL determines its characteristic MRI performance. Typical case of PCNSL can be diagnosed accurately by MRI
ABSTRACT
Objective: To study the effect and clinical value of mammography in the diagnosis of breast lump so as to improve the diagnosis level of breast cancer
Methods: A retrospective analysis was carried out on clinical data of 110 patients with mammary lump confirmed by pathology to study the compliance of mammography diagnosis and Pathology diagnosis in breast lump, and the detection of microcalcifications, phyllode, and observe the image performance of mammography. Taking infitrating ductal carcinoma [IDC] as an example, the correlation of image performance and clinical pathological features of different types was studied so as to predict if mammography performance was effective in the treatment and prognosis in breast cancer
Results: Taking Breast Imaging Reporting and Data System [Bl-RADS] grade 4A as the critical point, the sensitivity, specificity and accuracy of mammography was 90.80% [109/120], 84.60% [126/149] and 87.40% [235/269]; taking Bl-RADS grade 4B as the critical point, the sensitivity, specificity and accuracy of mammography was 85.00% [102/120], 93.30% [139/149] and 89.60% [241/269]; the correlation analysis suggested that, there was some kind of correlation between the mammography performance and clinical features of breast cancer
Conclusion: Mammography is worth being promoted in clinic for its significant clinical value in diagnosing and identifying breast lump
ABSTRACT
Acute lumbar sprain was divided into two types, one is the spine injury type, and the other is the non-spine injury type. All 30 cases with acute lumbar spine were treated with acupuncture and Tuina, and the results showed 27 cases were healed and 3 cases efficiency.
