Abstract


A 59-year-old female with history of progressive scleroderma and pulmonary fibrosis was referred for biopsy of a pulmonary nodule that was discovered on computed-tomography (CT) chest surveillance, not present on prior CT-scan.  Imaging was suspicious for granuloma, malignancy or aneurysm. CT-Angiography (CTA), performed immediately before the procedure, did not show enhancement of the mass, followed by placement of coaxial-needle into the mass. Suspicion of aneurysm was again raised and repeat CTA demonstrated contrast filling of the aneurysm. With the coaxial-needle in the aneurysm, embolization of the sac was performed using microfibrillar collagen, followed by confirmation of containment and thrombosis with CT.
