Lymphoproliferative malignancies constitute a wide spectrum of haematological malignancies and their prevalence is widely increasing. Non-Hodgkin lymphomas and Hodgkin disease, frequently involve extranodal soft tissue structures in the head and neck, thorax and abdomen. These malignancies may involve virtually any type of soft tissues to any extent; hence many different imaging manifestations are possible which may mimic other disorders. The imaging characteristics of extranodal lymphomatous soft tissue involvement are described and classified here according to the site of involvement in 6 cases (primary diseases with orbital, muscle, extra testicular, scalp, sinonasal and pachymeningeal/dural involvement). In majority of these cases at presentation we found a predominantly homogeneous soft tissue mass with mildly high attenuation on CT and a T2 intermediate signal on MRI at these sites without any manifestation of disease elsewhere but on follow-up two out of these six cases developed systemic disease elsewhere. Few consistent patterns were noticed on CT and MRI which might help to include lymphomas as an important differential diagnosis of soft tissue masses. Though a definitive diagnosis requires a biopsy (bone marrow, lymph node, or mass), and other laboratory tests, imaging primarily aims at staging of the disease and identification of new or recurrent disease.
