    (a, b) Contrast-enhanced axial CT shows the presence of anomalous gas in the lesser sac, with communication with the gastric lumen (arrow) consistent with a contained perforation.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    (a, b) Contrast-enhanced axial CT shows the presence of anomalous gas in the lesser sac, with communication with the gastric lumen (arrow) consistent with a contained perforation.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    (c) Contrast-enhanced coronal CT shows the presence of anomalous gas in the lesser sac (arrow), with communication with the gastric lumen consistent with a contained perforation.

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Inflammation;

    (d) Lung window axial CT better depicts the gastric wall discontinuity.

    Coeliacomesenteric trunk
     

    Axial (a) CT image show a large vessel originating from the aorta - the coeliacomesenteric trunk (CMT).

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    (b) shows the three main branches of the coeliac artery within the circle (from right to left - common hepatic artery, left gastric and splenic arteries).

     
    Area of Interest: Abdomen; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    Coronal (c) CT image show the CMT (arrow). Black arrowhead points to the short coeliac artery with an ascendent traject. White arrowhead points to the superior mesenteric artery.

     
    Area of Interest: Abdominal wall; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Congenital;

    The artery superior to the CMT originating in the aorta represents an accessory left gastric artery.
