To evaluate the performance of computed tomography (CT)-guided percutaneous biopsy of abdominal lesions.

Materials and Methods:

This retrospective, single-center study evaluated patients submitted to CT-guided percutaneous biopsy of abdominal lesions at a cancer center, between January 2014 and June 2015. The images and patient medical records were reviewed using a standardized data collection form.


We included 225 procedures performed in 212 patients, of whom 143 (63.5%) had a prior diagnosis of cancer. Of the 225 lesions biopsied, 88 (39.1%) had a suspected primary origin and 137 (60.9%) were suspected metastatic lesions. Complications occurred in only 14 (6.2%), the most common being self-limited bleeding, which occurred in 12 (85.7%) of the 14. The occurrence of complications was not found to be significantly associated with the lesion location, age of the patient, presence of comorbidities, use of a supplementary technique, vascularization pattern, or proximity of the lesion to large vessels. The pathology findings were sufficient for making the diagnosis in 202 cases (89.8%), and the diagnosis was consistent with the clinical suspicion in 132 (58.6%).


The procedure demonstrated a high (approximately 90%) rate of providing a sufficient sample for the diagnosis and a low complication rate, the most common complication being self-limiting bleeding.
