Abstract
OBJECTIVE: This study aimed to compare CT findings in patients with Epstein-Barr virus positive (EBV+) diffuse large B-cell lymphoma (DLBCL) of the elderly with CT findings in patients with Epstein-Barr virus negative (EBV-) DLBCL.
METHODS: We retrospectively identified 9 consecutive patients with EBV+ DLBCL (6 males and 3 females; aged 72-83 years, mean: 76.2 years) and 39 consecutive patients with EBV- DLBCL (19 males and 20 females; aged 53-91 years, mean: 71.3 years) who had undergone CT examinations between September 2007 and August 2016. In each type of disease, clinical and CT findings were evaluated.
RESULTS: No significant differences in B symptom incidence or serum lactate dehydrogenase levels were found between the two diseases. However, the prognosis of patients with EBV+ DLBCL was significantly poorer than that of those with EBV- DLBCL (p < 0.05). Nodal and extranodal necrosis was found in 6 (66.7%) of 9 patients with EBV+ DLBCL and in 6 (15.4%) of 39 patients with EBV- DLBCL (p < 0.005).
CONCLUSION: The CT finding of nodal and extranodal necrosis was significantly more frequent in patients with EBV+ DLBCL than in patients with EBV- DLBCL. Advances in knowledge: This is the first report on the CT findings in patients with EBV+ DLBCL of the elderly. Different CT findings are present in EBV+ DLBCL and EBV- DLBCL.
