Are all primary omental infarcts truly idiopathic? Five case reports

Figure 1 Omental infarction in a 36-year-old male. A and B: On contrast enhanced transverse (A) and coronal reformat (B) computed tomography images, fat thickening and stranding in omentum in the right upper quadrant formed an approximately 8 cm mass-like lesion with hyperdense peripheral halo (arrows).

Figure 2 Omental infarction in a 38-year-old male. On contrast enhanced transverse computed tomography images, focal area of fat thickening and stranding (arrows) was seen in the omentum adjacent to the transverse colon (TC).

Figure 3 Omental infarction in a 34-year-old man. A and B: On contrast enhanced axial (A) and coronal (B) computed tomography images, a mass like focal hyperdensity with peripheral fat stranding was seen in the left inframesocolic omentum (arrows).
