High ways for pathology
 Infection
 Fluid
 Neoplasm

3. Level I
•Upper
abdominal
spaces

4. Embryology

5. Peritoneal folds related to the Spleen& Kidney:-
• Gastrosplenic ligament.
• Splenorenal (lienorenal)
ligament:
connects the spleen to the posterior
abdominal wall over the left
kidney.

6. Lesser Sac

7. Is it important ?!
• Lesser sac fluid =
neighboring pathology

8. Perihepatic spaces

9. Glisson capsule and sheath

10. Cholecystitis

11. Cullen sign

12. Tumour spread

13. Level II
• Retroperitoneum

14. axial

15. Retroperitoneum.
Sagittal

16. Relation to midline

17. Inferior
extensions

18. Ilio-psoas
spaces
• The iliopsoas
compartment consists
of the psoas major,
psoas minor, and
iliacus muscles.
• The psoas major
muscle arises from the
transverse processes
of the 12th thoracic
and lumbar vertebrae
• merges with the iliacus
muscle at the level of
the L5 through S2
vertebrae to form the
iliopsoas muscle.

19. Level III
•Pelvis & down .

20. Pelvic spaces-sagittal

21. Pelvic spaces coronal

22. Perineal spaces

23. Perineal spaces-relation to thigh
