Fig. 1A. 50-year-old man with acute myeloid leukemia and histologically
proven invasive pulmonary aspergillosis in left upper lobe. Contrast-enhanced
axial CT scan of chest obtained at lung window settings shows nodule with
peripheral ground-glass opacity, representing halo sign.

Fig. 1B. 50-year-old man with acute myeloid leukemia and histologically
proven invasive pulmonary aspergillosis in left upper lobe. Contrast-enhanced
30-mm coronal maximum-intensity-projection image with clear depiction of
peripheral pulmonary arteries shows interruption of peripheral segmental
pulmonary artery at level of halo surrounding nodule, corresponding to
vascular occlusion (arrow).

Fig. 1C. 50-year-old man with acute myeloid leukemia and histologically
proven invasive pulmonary aspergillosis in left upper lobe. Magnified
contrast-enhanced 30-mm coronal maximum-intensity-projection image confirms
interruption of same peripheral segmental pulmonary artery (arrow) at
level of halo surrounding nodule.

Fig. 2A. 47-year-old man with non-Hodgkin's lymphoma and histologically
proven atypical Mycobacterium consolidation in left lower lobe.
Contrast-enhanced axial CT scan of chest obtained at lung window settings
shows focal area of air-space consolidation in posterior basal segment of left
lower lobe.

Fig. 2B. 47-year-old man with non-Hodgkin's lymphoma and histologically
proven atypical Mycobacterium consolidation in left lower lobe.
Contrast-enhanced 30-mm coronal maximum-intensity-projection image shows
patent arteries (arrowheads) inside focal consolidation in posterior
basal segment of left lower lobe without any evidence of occluded vessels.

Fig. 2D. 47-year-old man with non-Hodgkin's lymphoma and histologically
proven atypical Mycobacterium consolidation in left lower lobe.
Magnified contrast-enhanced 30-mm coronal-oblique maximum-intensity-projection
image confirms patent arteries throughout air-space consolidation in posterior
basal segment of left lower lobe.

Fig. 3A. 34-year-old man with cough and fever of unknown origin and
biopsy-proven mediastinal diffuse large cell lymphoma extending into lung
parenchyma. Contrast-enhanced axial CT scan of chest obtained at mediastinal
settings shows large solid lesion in middle lobe in contact with pleural
surface.

Fig. 3B. 34-year-old man with cough and fever of unknown origin and
biopsy-proven mediastinal diffuse large cell lymphoma extending into lung
parenchyma. Contrast-enhanced 30-mm axial maximum-intensity-projection (MIP)
image shows patent, tapering, and partially irregular vessels within solid
parts of lesion.
