MDCT Scan Evaluation of Abdominal Lymphoma

Introduction: Accurracy of CT in the staging of patients with lymphoma is widely recognized, and it is now the first investigation of choice in the initial staging and follow up of these patients. The current research aimed to study the role of CT scan of the abdomen in staging of the different types of the lymphoma, to study the differences of the involvement pattern and morphology among the different types of the lymphoma and to assess the role of the CT scan to characterize the morphology of primary lymphomas involving the hollow and solid abdominal viscera. Material and methods: The study was a retrospective survey from 2014 to 2015. CT scan abdomen was performed in 80 patients of histological proved lymphoma; All the scans were performed using 128 slice CT scanner Results: In this retrospective male preponderance study of 80 patients with proven lymphoma, positive findings were seen in 57 (71.2%) patients, with 46% of HD and 84% of NHL patients showed intraabdominal involvement CT accurately detected nodal and extranodal sites of involvement, Conclusion: Lymphnode involvement was the most common manifestation of lymphoma and it was seen in 66% of all the patients. CT showed the exact sites, the pattern of involvement, the morphological features and associated complications like encasement of the vessels, hydronephrosis, biliary obstruction, bony erosion, extramedullry cord compression etc. in both HD and NHL. Extranodal involvement was detected in -patients. The involvement of liver was seen in 28%, spleen in 26.3%, GIT in 14% and renal involvement was seen in 7% of the patients with positive findings. Other sites of involvement include pancreas, psoas muscle and vertebrae.
