Robotic‐Assisted CT ‐Guided Synchronous Percutaneous Lung Biopsy and Cryoablation for Pulmonary Sub‐Solid Nodule: A Case Report

ABSTRACT Percutaneous lung biopsy and cryoablation (CRA) under imaging guidance are safe and effective options in the diagnosis and treatment of pulmonary ground‐glass nodules (GGNs) with favourable outcomes. However, percutaneous puncture procedures conventionally require multiple freehand needle manipulations until a satisfactory needle position is achieved, which leads to unnecessary radiation exposure, complications and failure. Despite increasing utilisation of robotic‐assisted systems in recent years, literature describing their use in CT‐guided percutaneous lung biopsy and CRA for pulmonary GGNs remains limited. Herein, we report our initial experience with robotic‐assisted CT‐guided synchronous percutaneous lung biopsy and CRA of a mixed GGN that was accidentally discovered during a physical health examination in a 77‐year‐old female. The 14‐mm‐sized mixed GGN involving the anterior segment and apical segment of the right upper lobe was successfully biopsied and cryoablated without recurrence at the 7‐month follow‐up. This case highlights the feasibility, safety and greater accuracy of employing a novel robotic‐assisted system in lung biopsy and CRA for pulmonary sub‐solid nodules.
