Lymphoma pending drainage is an indication that the patient’s condition meets the criteria related to the diagnosis of lymphoma, but needs to be clearly diagnosed through pathological examination. The examinations that often show lymphoma pending drainage include color ultrasound, CT, puncture biopsy and so on. 1. Color ultrasound: patients with lymphoma may have enlarged lymph nodes under color ultrasound, and according to the size, border and blood supply of the lymph nodes, it also suggests that the possibility of lymphoma is high, but it needs to be further clarified by puncture biopsy, so there may be the result of lymphoma awaiting exclusion on the color ultrasound checklist. 2. CT: CT scanning and enhanced CT also have certain significance in the diagnosis of lymphoma, but still need puncture biopsy to make it clear, so the conclusion of lymphoma to be discharged may also appear on the CT checklist. 3. Puncture biopsy: although puncture biopsy is the gold standard for the diagnosis of lymphoma, it may not be able to be detected through pathological examination because of improper sampling in the process of puncture, so it will also show the conclusion of lymphoma awaiting drainage on the pathological list. Lymphoma pending drainage means that the lymphoma needs further tests to clarify the diagnosis. After the diagnosis of lymphoma, it is important to develop a reasonable treatment plan under the guidance of the doctor and treat it as early as possible.
