Content Objective To define a new radiological sign, the central hypo-attenuated lymph node in nodular sclerosis in Hodgkin’s lymphoma in computed tomography (CT).

Materials and methods Throughout the last year, all patients diagnosed with lymphoma were CT - scanned with intravenous non-ionic contrast. CT scans were evaluated by an expert pediatric radiologist and were later pathology- proven to be nodular sclerosis type.

Results 7 newly-diagnosed cases of nodular sclerosis Hodgkin’s lymphoma presented with the central hypo-attenuation of the compromised lymph nodes in the CT-scans. All of them were pathology-proven diagnosed with nodular sclerosis Hodgkin’s lymphoma.

Discussion We propose that the central hypo-attenuated lymph node sign is because of the accumulated lymph inside the compromised lymph node. This finding has been proven with pathology by the presence of collagen bands in the lymph node periphery. There’s still work to be done, a systematic retrospective study on all Hodgkin’s lymphoma at the moment of the diagnosis will determine the sensitivity, specificity, positive predictive value, and negative predictive values for this new radiologic sign.
