Abstract:
OBJECTIVETo explore the imaging characteristics of F-FDG PET-CT and clinical presentation of patients with primary hepatic lymphoma (PHL).
METHODSThe F-FDG PET-CT image data of 6 patients with pathologically diagnosed PHL, were retrospectively analyzed.
RESULTSThe six patients included 4 male cases and 2 female cases, with median age of 65 years old , and all the cases were diagnosed as diffuse large B-cell lymphoma. In regarding of F-FDG PET-CT imaging, all the cases showed hypodense masses and high FDG uptake, with homogenous density in 5 cases and necrostic area of low density in 1 case. The SUVmax was 6.3, 9.5, 12.8, 22.1, 28.4, and 33.5, respectively. Three typical PET-CT imaging findings were as follows: 4 cases appeared as multiple nodes, 1 case was the type of solitary mass, and 1 case was the type of diffuse infiltration. 5 cases showed a mild enhancement by CT scanning, and 2 cases displayed "blood vessel floating" in. In 2 cases, MRI scanning demonstrated low signal intensity on T1WI, and homogeneous signal intensity on T2WI with mild enhancement.
CONCLUSIONThe F-FDG PET-CT manifestation of PBL has a certain characteristics that can providt helpful to diagnose primary hepatic lymphoma.
