CT findings of acute ureteral obstruction (report of 3 cases)


Primary malignant lymphoma of the breast Li Fei, Yi-min, LIU Rui-fang, Su Lin [CLC] R445.1 [Document code] D [Article ID] 1681-2824 (2005) 11-1003-011 medical summary patients, female,ugg pas cher, 53 years old, 10 days ago accidentally discovered within the upper quadrant of the right breast with a large egg mass to hospital. Palpation: swelling material hard,abercrombie fitch madrid, no compression, can be active. No local swelling, ulceration, nipple discharge and no depression, no orange peel-like change. Ultrasound findings: in the inner upper quadrant of the right breast and a skin test a low heterogeneous lobulated hypoechoic nodules. Range of about 5.0cm × 2.m. Neat edge, no Crab-like changes, a complete capsule, tumor diameter was significantly smaller than the upper and lower front and rear tracks and trails around the rear echo significantly enhanced. Color Doppler flow imaging: tumor blood flow within the very rich, showing branched distribution, arterial peak flow speed (2m / s), resistance index is not high (0.68). Did not increase between the right costal exploration and lymph nodes. e right arm shows two oval-shaped lymph nodes increases, the range of large nodules about 1.m × 0.6m, Summary save 0.m × 0.3m, two nodules were seen significantly widened the center of the lymph gate strong back the vocal cords. Color Doppler flow imaging, the door can be seen only thin-shaped lymph flow signals. Ultrasound diagnosis: (1) within the upper quadrant of the right breast lesions, the possibility of large malignant. (2) increase the right axillary lymph nodes,nike store outlet, not excluding the possibility of lymph node reactive hyperplasia. Blunt dissection tumor resection surgery, for pathology, frozen section report: breast lymphoma. Carry out breast modified radical mastectomy. Pathological: Primary breast lymphoma, B cell type. Not involving the axillary lymph nodes (0 / 4). Immunohistochemistry: Wide protein () (a), L (+++), C5RO (+), C0 (+++). 2 Discussion Primary breast lymphoma (primarybreastlymphoma,ugg españa, PBL) rare, reported in the literature of primary breast cancer accounts for only 0.04% to 0.5% .... Reports on ultrasound diagnosis is particularly rare. Chinese ademy of Medical Sciences Cancer Hospital, Julius et al reported five cases (1958 to 1999) hospitalized patients, no case of preoperative ultrasound diagnosis. Comprehensive literature and Author: 300142 Tianjin, People's Liberation Army No. 254 Hospital, clinic subjects with special characteristics of this case, sum up sonographic features of PBL and identify points with breast cancer are as follows: (1) PBL mostly lobulated growth, larger mostly close to the oval-shaped, smaller anteroposterior diameter, and breast cancer are often greater than the anteroposterior diameter of the upper and lower tracks or so tracks, spherical and irregular shape. (2) PBL boundary definition, no lymphovascular invasion Crab-like performance, a complete capsule. Capsule-like breast cancer, no echo, in addition to small lesions, the edge showed a Crab-like changes. (3) PBL and breast cancer are not homogeneous internal echoes, internal echoes but lower PBL,ugg boots outlet, most of the region close to the echo. (4) breast cancer may have a small calcifications inside, PBL does not have this change. (5) Most breast cancer back echo attenuation, while the rear echo PBL was significantly enhanced. (6) earlier onset of breast cancer, ipsilateral axillary lymph node metastasis. PBL is generally larger size, but many such phenomenon. (7) PBL and more superficial location, located in the subcutaneous tumor edge (shallow) multi-echo-free mammary glands. Breast cancer is more in the gland layer, were seen around the glands echo around. (8) Color Doppler flow imaging: PBL and the majority of breast cancer are rich in nutrients and blood vessels, but the PBL richer blood flow. Both the peak blood flow velocity were faster, but the vast majority of breast cancer increased arterial resistance index> 0.75, while the PBL resistance index increased significantly (Figure 1). In addition, the combination of clinical findings: PBL non-inverted nipple breast cancer of the skin, skin irritation, ulceration, and orange peel-like change, and no nipple discharge. Although palpation hard, but still active, etc., should be able to make a prompt report of ultrasound diagnosis. (is picture Annex page 2) [
