Enhanced ultrasonography detection of mucosa-associated lymphoid tissue of the liver with penetrating vessels in a tumor -case report

A case of primary hepatic extranodal marginal zone B-cell mucosa-associated lymphoid tissue (MALT) lymphoma treated by radiofrequency ablation (RFA), and a literature review

“…To the best of our knowledge, 113 cases of primary hepatic MALT lymphoma have been reported in 71 articles to date, 7 – 37 of which 80 cases (including our case) had relatively detailed clinical data ( Table 1 ). Among the patients in these 113 cases, 43 patients were men (38%) and 48 were women (42%) (the sex was not indicated in the remaining cases), with an age range of 30 to 89 years and a median age of 63.5 years.…”

“…In previous reports, PET-CT was performed in 18 cases, and all hepatic MALT lymphomas showed high metabolism with 18F-FDG. 7 , 9 , 11 , 19 , 23 , 26 , 32 , 35 , 40 , 54 – 57 Although the standardized uptake value (SUV) is the most widely used parameter in MALT lymphoma, this measurement is easily affected by many factors. Albano et al.…”

“…In previous reports, PET-CT was performed in 18 cases, and all hepatic MALT lymphomas showed high metabolism with 18F-FDG. 7,9,11,19,23,26,32,35,40,[54][55][56][57] Although the standardized uptake value (SUV) is the most widely used parameter in MALT lymphoma, this measurement is easily affected by many factors. Albano et al 52 recommended that other metabolic parameters (such as metabolic tumor volume (MTV) and total lesion glycolysis (TLG)), which include both morphological and metabolic characteristics, may be useful in predicting treatment response and prognosis.…”
