Extranodal lymphomas of abdomen and pelvis: imaging findings and differential diagnosis

摘要

A wide spectrum of extranodal lymphomas in the abdomen and pelvis is commonly encountered by imaging. Diagnosing these lesions generally requires a multimodality approach. This review highlights imaging appearances of extranodal lymphomas in the abdomen and pelvis with emphasis on computed tomography, magnetic resonance imaging, and positron emission tomography–computed tomography along with the relevant differential diagnosis.
