case_images: Initial CT with 3D reconstruction suggested a high degree of stenosis at the LSPV inlet (Figure 1). CT 3-D reconstruction imaging demonstrated the reestablishment of the LSPV (Figure 1).

case_images: A V/Q scan revealed normal bilateral ventilation (V) but with moderately decreased perfusion (Q) of the left upper lung (Figure 2).

case_images: This V/Q mismatch defect (Figure 3) supports the CT scan findings of severe stenosis of the LSPV. Consequently, the V/Q mismatch decreased; however, this was not entirely resolved (Figure 3).

case_images: Post-procedural imaging was conducted using a hybrid SPECT/CT scanner, where lung scintigraphy was performed (Figure 4).

case_images: Subsequent imaging conducted 2 and 3 months later revealed a ventilation-perfusion mismatch in the left upper lobe of the lung on the V/Q scan and a worsening of the stenosis on the CE-CT scan (Figure 6).

case_images: PTA was then performed, and serial postprocedural imaging revealed a gradual improvement of lung perfusion on the affected lobe (Figure 7).
