ABSTRACT
Objectives: To evaluate some radiological characteristics of solitary tumoral lesions in the lung and assess the value of lung biopsy
under computed tomography (CT). Methods: A prospective and cross-sectional study was conducted on 68 patients who had a
solitary pulmonary tumoral lesion; the patients underwent transthoracic biopsy under the guidance of CT in the Department of
Diagnostic Imaging of K hospital and Saint Paul hospital from March 2018 to May 2019. Results: Of 68 patients, 56 and 12 cases
found to be malignant and benign lesions, respectively, by biopsy. There was a difference in size between the cancer group and non
– cancer group. Lobulation and speculation margin is capable of advanced cancer. The overall complications of the transthoracic
biopsy were 47.05%. The incidence of parenchymal hemorrhage and pneumothorax was 36.8% and 10.3%. The incidence of
pneumothorax was related to the pleural needle angle (p= 0.001). Conclusions: CT-guided transthoracic needle biopsy is an effective
and safe diagnostic method for patients with a solitary pulmonary nodule or mass lesions. Pulmonary hemorrhage is the most
common complication after CT-guided percutaneous transthoracic biopsy.
