  • Figure 1
    Abdominal Ultrasound

    Ultrasound evaluation of epigrastic area shows a hyperechoic lesion (arrow) between the left hepatic lobe (L) and the stomach (S). This lesion was painful and noncompressible. P: Pancreas; A: Aorta; IVC: Inferior Vena...

     
    Area of Interest: Abdomen; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 2
    Abdominal Ultrasound

    On ultrasound the echogenic aspect of the lesion (arrow) is suggestive of being lipomatous, and it cannot be easily discriminate from the adjacent hyperechoic pancreas (P).

     
    Area of Interest: Abdomen; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Tissue characterisation;
     
     
  • Figure 3
    Color Doppler Ultrasound

    No vascular flow is present within the lesion on color Doppler ultrasound interrogation.

     
    Area of Interest: Abdomen; Imaging Technique: Ultrasound-Colour Doppler; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 4
    High-resolution Ultrasound

    High-resolution probe ultrasound evaluation shows attenuation on the posterior aspect of the lesion (*).

     
    Area of Interest: Abdomen; Imaging Technique: Ultrasound; Procedure: Diagnostic procedure; Special Focus: Inflammation;
     
     
  • Figure 5
    Axial contrast-enhanced CT (soft tissue window)

    A fatty lesion (arrow) with hyperattenuating streaks is seen between the left hepatic lobe and the lesser gastric curvature.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 6
    Coronal reconstruction contrast-enhanced CT (soft tissue window)

    The lesion shows mass effect on lesser gastric curvature and is situated between the liver (L) and the stomach (S), an area that corresponds to the lesser omentum.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Ischaemia / Infarction;
     
     
  • Figure 7
    Sagittal reconstruction contrast-enhanced CT (soft tissue window)

    The hyperattenuating lesion on a sagittal view (arrow). Also small amount of free fluid is seen in the Douglas pouch (*).
