CT-guided biopsy of malignant lymphoma / 介入放射学杂志

ABSTRACT

Objective To evaluate the value of CT-guided biopsy of deep-located lesion in the diagnosis of lymphoma. Methods CT-guided percutaneous biopsy was performed in 58 patients with 16-20 gauge core-needle biopsy. The locations of lesion involved mediastinun, lung, retroperitonurn, spleen, kidney, adrenalal and musculoskeletal system. Pathology examination included hematoxylin and eosin staining and immunohistochemical assays. Results In 56 out of 58 cases,the biopsy findings could be confirmed by histologic examination including correctly diagnosed 47 malignant lymphomas, corresponding to a sensitivity of 81%;with fuithecmace subclassification 42 of the 47(89.4%) could be as diagnosed malignant lymphomas on the basis of CT-guided biopsy. Conclusions Biopsy of deeply located lymphoma mass under CT guidance has high diagnostic accuracy and low complication rate with convenience for subclassification of malignant lymphomas.
