CT-Guided Percutaneous Needle Biopsy in Patients with Suspected Retroperitoneal Fibrosis: A Retrospective Cohort Study

Purpose The outcome of CT-guided biopsy in patients with suspected retroperitoneal fibrosis (RF), regarded as technically challenging, remains unclear. This study aimed to evaluate the results of CT-guided biopsy in patients with lesions considered in the differential diagnosis of RF and compare them with results from patients with other retroperitoneal lesions.
