Abstract: Objective To summarize the imaging features of the primary extranodal lymphoma (PENL)and evaluate the diagnos-tic value.Methods The clinical manifestations,imaging findings and pathological types of 50 patients with PENL were analyzed retrospectively.Results Fifty patients of PENL included 4 cases in orbit (8.0%),1 in middle ear and mastoid (2.0%),5 in thyroid (10.0%),2 in breast (4.0%),8 in lung (16.0%),5 in stomach (10.0%),15 in intestine (30.0%),1 in adrenal gland (2.0%),5 in testis (10.0%),2 in prostate (4.0%)and 2 in soft tissue of shoulder and hip (4.0%).In all patients,the nodular type was 40% (20/50),diffuse type was 34% (17/50)and massive type was 26% (13/50).Most lesions were regular (54%,27/50)and had clear margin (94%, 47/50).26 cases (52%)were non-Hodgkin's lymphoma with diffuse large B cell type.Conclusion The imaging findings of PENL are various and nonspecific,which may be easily misdiagnosed.Various imaging methods have different sensitivity for the diagnosis of lymphoma in different sites.
