Other non-neoplastic processes that may manifest as intraluminal filling defects
on excretory phase images include fungus balls, blood clots, sloughed papilla in the setting of papillary necrosis (Figure 11).
Chest CT was performed for further evaluation of the lungs and major vessels in the neck, which revealed multiple bilateral lung consolidations and atelectatic changes and filling defects

Once it reached the target site, a second epidurogram was obtained by injecting 3 mL of the contrast agent for the identification of filling defects
