Value of spiral CT and endoscopic in the diagnosis of primary gastrointestinal malignant lymphoma

[Objective] To study the clinical, endoscopic and CT of primary gastrointestinal malignant lymphoma (PGIML). [Methods] The clinical, endoscopic and CT data in 45 cases of primary gastrointestinal malignant lymphoma were reviewed retrospectively. All cases were confirmed with histological specimen obtained from endoscopic biopsies or surgery. [Results] The main clinical feasures of PGIML patients was abdominal pain.The incidence of PGIML was highest in stomach, seen in 32 of 45 patients (71.1%). The positive rate of endoscopic biopsy, EUS and CT for the diagnosis of PGIML was 55.6.1% (20/36), 100% and 66.7% (20/30) respectively. B-cell lymphoma was the predominant type, seen in 42 of 45 cases (93.3%). [Conclusions] Abdominal pain was the most common symptom and the stomach was the most location in PGIML. Endoscopy and CT examination can improve the accuracy of diagnosis of PGIML. Endoscopic ultrasonography was meaningful for the diagnosis of PGML.
