Chest X-ray showed a well defined consolidated area in the medial and basal portion of left lung (Fig. 1).

Angiography revealed the presence of a smooth bordered consolidation in the left posterior basal para-vertebral region. (Fig. 2, Fig. 3). A systemic feeding artery originating from left posterior lateral wall of the descending aorta was revealed. (Fig. 4, Fig. 5a and b).

Angiography revealed the presence of a smooth bordered consolidation in the left posterior basal para-vertebral region. (Fig. 2, Fig. 3). A systemic feeding artery originating from left posterior lateral wall of the descending aorta was revealed. (Fig. 4, Fig. 5a and b).
Pre embolization digital subtraction angiography after selective catheterization of the left bronchial artery - showing single feeding artery later dividing into two branches to supply the sequestered portion resulting in blush on DSA.

Post embolization DSA revealed marked reduction of the abnormal vascular blush and occlusion of the feeding artery. (Fig. 7, Fig. 8).
Follow up contrast CT of the patient after 3 months showing occlusion of vascularity and minimal reduction in size of the sequestered portion.
