Abstract:
Objective To analyze the CT features of primary adrenal lymphoma (PAL)in order to improve the diagnosis of the disease.Methods Clinical and CT findings of 1 1 patients with pathologically confirmed PAL were retrospectively analyzed.Results 18 lesions (10 on the right side,and 8 on the left)were found in all 11 cases of PAL (bilateral lesions in 7 cases).The maximum diameter ranges of the lesions were from 3.8 cm to 12.0 cm (M ± SD:6.5±2.3 cm).The shapes of the lesions were shown as round (2/18),oval (9/18)or irregular (7/18).The plain CT showed all lesions with isodensity or lowGdensity,and the CT attenuation value ranged from 24.5 to 46.3 HU (mean 33.6±5.7 HU).The contrastGenhanced CT showed 16 lesions with slightGmoderate and gradual enhancement,1 lesion with nonenhancement and other 1 with severe enhancement.The CT value of the lesions ranged from 24.9 to 71.4 HU (M±SD:45.1 ± 12.1 HU)in arterial phase and 23.8 to 7 9.9 HU (M±SD:5 5.0±1 3.4 HU)in venous phase.The cystic degeneration in 8 lesions,infiltration of peripheral organs and vessels in 8 lesions,and peritumoral lymphadenectasis in 1 lesion were seen.In the 1 1 cases with 4－48 month followGup after chemotherapy,9 lesions decreased or disappeared,and other 2 decreased first but then increased.Conclusion PAL predominantly occurs in the bilateral adrenal glands and represents isoGlow density soft tissue mass on plain CT.Contrast enhanced CT shows the the solid parts of lesions mostly with mild to moderate gradual enhancement.In addition,the larger lesions are prone to have cystic degeneration and invade surrounding tissues and organs.
