Objective: To evaluate the efficacy,
feasibility and safety of contrast-enhanced CT-guided core biopsy of
retroperitoneal masses. Materials and Methods: Contrast-enhanced CT-guided
biopsy of retroperitoneal masses was performed in 26 patients.
Histopathological diagnosis was obtained and accuracy was calculated. Two
blinded radiologists determined feasibility of biopsy procedures on routine
CT-guidance, and compared accessibility of target lesions using contrast-enhanced and non-contrast-enhanced CT. Results:
Satisfactory samples were obtained in all 26 patients and pathological
diagnosis was made in 24. Accuracy was 95.5%. Routine CT-guided biopsy
punctures were not satisfaction in 4/26 patients, and contrast-enhanced CT
scans rendered the target lesions more accessible in 16 patients. Conclusion:
Contrast-enhanced CT-guided biopsy increases the feasibility of biopsy of retroperitoneal
masses.
