Abstract:
Postoperative pneumothorax in posterior fusion using pedicle screws is uncommon, but the complication needs to be kept in mind. There are reports of a pseudopneumothorax resulting from artifacts. We report a unique case of a pseudopneumothorax in a patient with scoliosis, diagnosed using O-arm intraoperative computed tomography. The pseudopneumothorax, initially appearing on a chest radiograph, turned out to be an area of partial atelectasis at the lateral border of the right lower lobe. Spine surgeons and anesthesiologists must recheck images and maintain a high degree of suspicion for a pseudopneumothorax when the radiographic image during scoliosis surgery does not match the patient's condition.

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
Radiological Investigation III: Pulmonary Angiogram and PET Scan
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
