Figure 1: A 58-year-old male patient with liver neoplasm located in the segment VIII who developed pneumothorax after undergoing transpulmonary radiofrequency ablation with one bipolar electrode. (a) Preprocedural axial arterial phase computed tomography scan obtained at the level of hepatic dome showed ring-like enhancing mass at segment VIII of liver. he size of the mass was 1.05 cm × 1.38 cm. (b) Intraoperative computed tomography scan showed the electrode with working length of 20 mm passing through the lung parenchyma and was accurately inserted into the lesion. (c) Postprocedural axial arterial phase computed tomography scan showed oval-shaped ablation zone with low attenuation, the enhancing rim which along the periphery of the ablation zone appears to be a relatively concentric and symmetric area with smooth inner margins. (d) Postprocedure image demonstrated a small amount of pneumothorax in the right thorax. The track of the electrode demonst ated strip-shaped hemorrhage in the lung parenchyma
