    Abstract:
    AIM: We performed a retrospective study of 267 core needle aspiration biopsies in order to estimate the accuracy of CT-guided aspiration core needle biopsies for the diagnosis and subsequent treatment of malignant lymphoma. MATERIALS AND METHODS: Between 1989 and 1999, 267 CT-guided core needle biopsies were performed in 241 patients with either primary or recurrent malignant lymphoma. Patients age ranged from 4--88 years. One hundred and sixty-six (62.2%) nodal and 101 (37.8%) extranodal aspiration biopsies were performed using either 18G or 20G Turner needles. Statistical method used was Chi-square analysis. RESULTS: An accurate histological diagnosis was made in 199 (82.5%) patients, the remaining 42 (17.4%) patients had non-diagnostic CT biopsies. Thirty-seven of them were diagnosed by a surgical biopsy, four by bone marrow biopsy and in one patient by paracentesis. One hundred and seventy-nine patients had non-Hodgkin's lymphoma (NHL) and 62 had Hodgkin's disease (HD); 23 (9.54%) patients underwent repeated CT biopsy which was diagnostic in 17 (73.9%) and non-diagnostic in six (26%). CONCLUSION: CT-guided aspiration core biopsies were sufficient to establish a diagnosis in lymphoproliferative disorders in 82.5% of cases. In the light of this experience we suggest that imaging-guided core needle biopsy be used as the first step in the work up of many patients with lymphoma.
