Hemothorax is a rare yet serious complication of percutaneous lung biopsies with reported incidence of 0.092%.1 This is most commonly due to the injury to the intercostal artery or internal mammary artery. However, bleeding due to pulmonary artery involvementis rare and wereport one such case which was managed by percutaneous glue embolization.  \nCase Report  \nA 67-year-old man with chronic kidney disease, anemia, chronic obstructive pulmonary disease, and weight loss presented with a 5.5 􀀁 4 cm mass with spiculated marginsin the right upper lobe on the CT chest ( ►Fig. 1). CT-guided biopsy was performed using a coaxial system of 18G 16-cm long and 2-cm throw. Postbiopsy CT showed mild hemothorax. The patient started complaining of mild pain with a gradual increase, and the need for oxygenation increased  \narticle published online June 11, 2025  \nDOI [https://doi.org/](https://doi.org/)[ ](https://doi.org/)10.1055/s-0045-1809414 . ISSN 0971-3026.  \nfrom 2 to 5 L. A noncontrast CT performed after 1 hour showed an increase in hemothorax occupying half of the right hemithorax ( ►Fig. 2A). The patient did not have any episodes of hemoptysis. Ultrasound (USG) screening revealed a peripheral pulmonary artery pseudoaneurysm adjacent to the pleura measuring approximately 15 􀀁 14mm, confirmed with CT angiography ( ►Fig. 2B–D).  \nGiven the peripheral location and visibility on USG, it was decided to treat the pseudoaneurysm percutaneously under USG and CT guidance. Under USG guidance, the pseudoaneurysm sac was percutaneously punctured with a 22G lumbar puncture needle and injection of glue: lipiodol mixture (1:5 dilution) was performed after carefully positioning the needle within the neck of the pseudoaneurysm ( ►Fig. 3A). USG and CT angiography confirmed complete thrombosis of the pseudoaneurysm with glue cast seen along the peripheral pulmonary artery ( ►Fig. 3B ). Postprocedure, his oxygen requirement came down subsequently with no further increase in hemothorax and the patient was discharged after 2 days in stable condition. Serial USG thorax was performed for monitoring the hemothorax. As the  \n© 2025 . Indian Radiological Association.
