case_images: Comparison of chest and abdominal CT scans before and after admission. (A) Transverse section of chest HRCT upon admission shows a large bulla in the red arrow region due to COPD. (B) Coronal section image of the chest before hemoptysis shows a newly developed solid nodule in the right lung. (C) Abdominal CT at admission shows no abnormalities in the gallbladder artery. (D) Follow-up chest HRCT image 1 week after admission shows a new solid nodule with a diameter of 21 x 18 mm in the posterior segment of the right lower lobe (red arrow). (E) Coronal section image of the chest after hemoptysis shows a newly developed solid nodule in the right lung. (F) Emergency abdominal CT image taken after abdominal pain and vomiting shows a newly appeared circular low-density dark area at the gallbladder artery (yellow circle).

case_images: Contrast-enhanced CT scan of the patient's lungs. (A,D) Curved planar reconstruction images reveal the dilation of the pulmonary artery at its distal end, forming a pseudoaneurysm (yellow arrow). (B,C,E,F) Volume rendering technology images clearly show a nearly spherical mass pseudoaneurysm at the distal end of the right pulmonary artery (red arrow).

case_images: Further contrast-enhanced CT imaging confirmed the diagnosis of a pseudoaneurysm of the pulmonary artery in the same location (Figure 2).

case_images: Aortic CTA examination after hematemesis. (A,D) Delayed enhancement of the pseudoaneurysm of the gallbladder artery (encircled in red) during the arterial phase of CTA. (B,C,E,F) Reconstructed three-dimensional images clearly show a spherical pseudoaneurysm at the exit of the gallbladder artery. (E) Reconstructed coronal section image shows an enhanced pseudoaneurysm image below the gallbladder.
