Computed tomography of primary XXXX .

@entity1 @entity242 @entity5 @entity8678 @entity1893 @entity1821
The CT examinations and medical records of 33 @entity1 with primary @entity5 were reviewed. Computed tomography findings were then compared with those from scans performed on 122 @entity1 with @entity1893 who presented during the same time interval. @entity8678 had three distinct CT appearances. Twenty-one @entity1 (64%) had large soft tissue masses. Seven @entity1 (21%) had masses with fatty density components, and five @entity1 (15%) had @entity5 that were primarily of water attenuation. With the exception of those @entity1821 that contained recognizable fat, CT could not distinguish among the different cell types. Seventeen @entity1 with @entity1893 had large dominant retroperitoneal soft tissue masses that resembled primary @entity5 . In most cases, however, CT was able to differentiate these @entity5 masses from @entity5 . Although 19 of 20 @entity242 of soft tissue attenuation were heterogeneous, only six of the 17 lymphomas presenting as dominant masses had such an appearance. Computed tomography is extremely helpful in initially evaluating @entity1 with @entity5 and in assisting the surgeon in planning his or her approach by accurately defining @entity5 extent.
