Pulmonary sequestration is a rare congenital anomaly, occurring in as many as 6% of patients with congenital pulmonary malformations. Focal aneurysmal dilation of the systemic feeding artery is even more uncommon. HistoriFrom the Department of Radiology, North Shore University Hospital, Hofstra North Shore–Long Island Jewish School of Medicine, 300 Community Dr., Manhasset, NY 11030.

cally, treatment for these lesions has been surgical excision. In recent years, there has been increased success with endovascular treatment, but with only one case published in the English-language literature. We report a case of a 73year-old man with a dysplastic 2.8 ⫻ 1.8 cm aneurysm (curved arrow, Fig 1) of the feeding systemic artery (straight arrow, Fig 1) supplying a right lower-lobe pulmonary sequestration. The lesion (Fig 2) was coil-embolized by using detachable platinum and hydrogel-coated coils and 2 mL of 40% N-butyl cyanoacrylate mixed with Ethiodol and tantalum (Fig 3) to achieve complete and persistent obliteration of the aneurysm. A follow-up magnetic resonance angiographic scan was obtained after 19 months, which demonstrated continued obliteration of the aneurysm (Fig 4).
