PURPOSE: To evaluate the imaging and clinical features of @entity54273 and to describe the phenomenon of diurnal variation in the size of @entity54273 in @entity1 with @entity3008 . MATERIALS AND METHODS: One hundred twenty-eight @entity1 with @entity3008 underwent chest and abdominopelvic computed tomography (CT). Thirteen @entity1 underwent CT in the morning and afternoon of the same day to assess diurnal variation in @entity54273 size. RESULTS: Twenty-seven of 128 @entity1 (21%) had 54 @entity54273 . The vast majority (96%) of these masses contained material of low attenuation at CT. Associated CT findings included enlarged abdominal lymph nodes, @entity1143 , @entity843 , and dilatation of the thoracic duct. The prevalence of @entity54273 was 15% in @entity1 who had mild @entity358 , 19% in @entity1 who had moderate disease, and 26% in @entity1 who had severe disease. Diurnal variation in size of masses was demonstrated in 12 of 13 @entity1 . Seven of the 27 @entity1 who had masses underwent biopsy; all seven were confirmed to have @entity54273 . The most common symptoms associated with @entity54273 were @entity11035 , @entity490 , and @entity4 of the lower extremities. The majority of the @entity1 reported worsening of symptoms as the day progressed. CONCLUSION: @entity54273 are common in @entity1 with @entity3008 . Diurnal variation in size may explain worsening of symptoms during the day.
