Figure 1: 18F-fluorocholine positron emission tomography/computed tomography (a) MIP revealed focal radiotracer uptake in upper neck on the left side (thick arrow). In addition, multiple foci of increased fluorocholine uptake noted over left shoulder, chest wall and right arm regions (black arrows) corresponding to brown tumors. Fused positron emission tomography/computed tomography (b) and computed tomography (c) images showed soft tissue nodule in the left lateral neck, posterior to left sternocleidomastoid muscle (thick arrow). Four-dimensional - computed tomography (d-f) demonstrated an intensely enhancing lesion (arrow) on arterial phase with washout in venous phase posterior to the left jugular vein at thyroid cartilage level suggesting ectopically located PA
