title: Extranodal lymphomas of abdomen and pelvis: imaging findings and differential diagnosis.
abstract: 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.
