Non-Hodgkin and Hodgkin lymphomas frequently involve many structures in the abdomen and pelvis. Extranodal disease is more common with Non-Hodgkin’s lymphoma than with Hodgkin's lymphoma. Though it may be part of a systemic lymphoma, single onset of nodal lymphoma is not rare. Extranodal lymphoma has been described in virtually every organ and tissue. In decreasing order of frequency, the spleen, liver, gastrointestinal tract, pancreas, abdominal wall, genitourinary tract, adrenal, peritoneal cavity, and biliary tract are involved. The purpose of this review is to discuss and illustrate the spectrum of appearances of nodal and extranodal lymphomas, including AIDS-related lymphomas, in the abdominopelvic region using a multimodality approach, especially cross-sectional imaging techniques. The most common radiologic patterns of involvement are illustrated. Familiarity with the imaging manifestations that are diagnostically specific for lymphoma is important because imaging plays an important role in the noninvasive management of disease.

Objective Textiloma and gossypiboma are terms used to describe a mass of cotton matrix that is left behind in a body cavity during an operation. This is an uncommon surgical complication. Gossypibomas are most frequently discovered in the abdomen. Such foreign bodies can often mimic tumors or abscesses clinically or radiologically; however, they are rarely reported because of the medicolegal implications. The manifestations and complications of gossypibomas are so variable that diagnosis is difficult and patient morbidity is significant. Conclusion This article discusses the clinical manifestations, pathophysiologic aspects, and most important complications related to gossypibomas; presents the classic imaging features of gossypibomas using a multitechnique approach; and shows some of the typical and atypical sites of gossypibomas.
