Transthoracic needle biopsy (TNB) is usually avoided in the presence of pneumothorax. The authors performed computed tomography (CT)-guided transthoracic core biopsy in the presence of pneumothorax in 13 patients (4.9%) selected from 265 patients who received CT-guided TNB over 4 years. These iatrogenic pneumothoraces were induced by previous ultrasound (US)-guided TNB (n = 5), transbronchial lung biopsy (n = 4), and CT-guided biopsy (n = 4). ⋯ A successful second biopsy was performed 7 days later after full expansion of the lung. There were no complications related to the procedures. The authors' experience suggests that CT-guided transthoracic core biopsy using small-bore coaxial technique can be safely performed with high-diagnostic yield in patients with stable iatrogenic pneumothorax.
