Bowel Abdominal wall musculature Cecum ILEOCECAL JUNCTION Terminal ileum Anatomy: Abdomen Iliacus muscle Psoas muscle Iliac blade Abdominal wall musculature Anterior lip of leocecal junction Posterior lip of ileocecal junction Ileocecal junction Ileocecal valve en face (Top) Transverse ultrasound through the RIF shows the cecum, which is represented by curvicurvilinear echogenicity with posterior reverberation. Note the terminal ileum compressed by the curvicurvilinear probe between the abdominal wall musculature and the iliopsoas complex posteriorly. (Middle) High-resolution transverse ultrasound through the RIF shows echogenic (fatty) lips of a normal ileocecal valve. (Bottom) Oblique right sagittal ultrasound through the RIF in the same patient shows the ileocecal junction end on. 79

Bowel Anatomy: Abdomen APPENDIX Subcutaneous adipose tissue Abdominal wall musculature Appendix Tip of appendix Psoas muscle Abdominal wall Appendix Tip of appendix Short axis of normal appendix (Top) Coronal oblique ultrasound through the RIF shows a long-axis normal appendix with a stratified mural appearance. Note the absence of peri appendicular inflammatory changes. (Middle) Transverse oblique ultrasound through the RIF shows a blind-ending tubular structure with a gut signature representing the long-axis view of a normal appendix. (Courtesy A. Law, MD.) (Bottom) Transverse oblique ultrasound through the RIF shows the short-axis view of a normal appendix with preservation of gut signature. Note the normal appearance of peri appendicular fat.
