title: Non-Hodgkin lymphoma mimicking primary retroperitoneal tumour on computed tomography.
abstract: We report a case of non-Hodgkin lymphoma with CT showing a single, bulky, and round retroperitoneal mass mimicking primary retroperitoneal tumours or metastatic lymph node. On MRI, the tumour was presumed originating from lymph nodes but we could not judge whether the tumour was due to lymphoma or metastasis.
