Abstract

Objectives: This study aims to evaluate the value of CT- guided core needle biopsy in diagnosis retroperitoneal masses at K hospital. Marterial and methods: 37 patients were diagnosed with retroperitoneal mass based on clinical, ultrasound and CT - scanner, were taken CT -guided core needle biopsy preoperative by 16 - 18 G - semi - automatic biopsy at Department of diagnostic imaging of K hospital. All patients had result of pathological diagnosis post – biopsy and post – operative from October 2021 to October 2022. It is descriptive cross-sectional, prospective study. Results: All of patient’s specimens has been pathological diagnosed. In there, 29 cases got malignant masses, and 8 cases got benign mases. 3 cases got mild complication as a small hematoma around the lesion after biopsy processing, 1 case got pain requiring analgesics. There were not any cases got serious bleeding complication, infection and not any cases had tumor transplant complications on the biopsy path with a follow-up period of 3 months. Sensitivity, specificity, positive diagnostic value, negative diagnostic value, and accuracy of  CT – guided core needle biopsy in diagnosis retroperitoneal masses were 93.1%, 100%, 100%, 80%, 94,6%, respectively. Conclusions: CT-guided core needle biopsy for retroperitoneal masses is safe and high valuable method in diagnosing the retroperitoneal tumor’s pathology.
