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).

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).

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

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.

To identify the cause of abdominal pain and vomiting, we conducted computed tomography angiography (CTA) of the entire aorta, which revealed a newly formed pseudoaneurysm in the gallbladder artery (Figure 3).
