The positron emission tomography/computed tomography scan of a young male, showed increased fluorodeoxyglucose (FDG) uptake in right perihilar lung lesion [black arrow in Figure 1a and red arrows in Figure 1b] compatible with known lung neoplasm. Maximum intensity projection image also showed increased FDG uptake in accessory muscles of respiration-bilateral sternocleidomastoid and intercoastal muscles [blue arrows in Figure 1a] and unilateral, intense FDG uptake in left hemi-diaphragm [red arrows in Figure 1a and c]. On CT, there was no morphological abnormality in any of the above-mentioned muscles with FDG uptake

The PET/CT scan showed increased FDG uptake in right perihilar lung lesion [black arrow in Figure 1a and red arrows in Figure 1b] compatible with known lung neoplasm. Maximum intensity projection image also showed increased FDG uptake in accessory muscles of respiration-bilateral sternocleidomastoid and inter coastal muscles [blue arrows in Figure 1a] and unilateral, intense FDG uptake in left hemi-diaphragm [red arrows in Figure 1a and c].
Coronal computed tomography (CT) image revealed elevated right hemi-diaphragm [arrow in Figure 2a], suggestive of right diaphragmatic paralysis. Fused positron emission tomography/CT image [coronal slice, arrow in Figure 2b], shows intense fluorodeoxyglucose uptake in left hemi-diaphragm. The maximum standardized uptake value of this uptake was 6.1 (normalized for body surface area)
