Importance
Level I
•Upper abdominal spaces
Embryology
Peritoneal folds related to the Spleen& Kidney:-
• Gastrosplenic ligament.
• Splenorenal (lienorenal) ligament:
connects the spleen to the posterior abdominal wall over the left kidney.
Lesser Sac
Is it important ?!
• Lesser sac fluid = neighboring pathology
Perihepatic spaces
Glisson capsule and sheath
Cholecystitis

Tumour spread
Level II
•Retroperitoneum
axial
Retroperitoneum.Sagittal
Relation to midline
Inferior extensions
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.
Level III
•Pelvis & down .
Pelvic spaces-sagittal
Pelvic spaces coronal
Perineal spaces
Perineal spaces-relation to thigh
•Now let’s apply
