Peritoneal Cavity notes Flashcards
Outer layer, lines the walls of the cavity
parietal peritoneum
Inner layer, covers abdominal organs
visceral peritoneum
Small intestine suspended from the posterior
abdominal wall by
mesentary
Transverse colon suspended from the posterior
abdominal wall by the
transverse mesocolon
Sigmoid colon suspended from the posterior
abdominal wall by the
sigmoid mesocolon
The lesser sac communicates with the greater sac
through this small opening
epliploic foramen
The space b/w the liver, pancreas,
& stomach.
lesser sac
pouch of douglas/rectouterine pouch is the equivalent to what in men
rectovesicle pouch
Double layer of peritoneum, extending from the liver
to the lesser curvature of the stomach
lesser omentum
Apron-like fold of peritoneum that hangs from the
greater curvature of the stomach
greater omentum
above diaphragm
pleural
Mass is confirmed to be within the
retroperitoneal cavity when there is
anterior displacement of kidneys/ureters
Retroperitoneal lesions displace echoes
ventrally and cranially
hepatic and subhepatic lesions produce what displacement
inferior and posterior
divides the subphrenic space into right and left components
falciform ligament
Left coronary ligaments anatomically separate
the subphrenic space into
anterior and posterior compartments
Connects the gastric greater curvature to the
superior splenic hilum
gastrosplenic ligament
Separates the lesser sac from the
renosplenic recess
splenorenal ligament
Rectus muscles are seen as a biconvex muscle
group delineated by the
linea alba and linea semilunaris
Extrahepatic loculated collections of bile. May develop because of trauma, GB disease, or biliary surgery
biloma abscess
Malignant solid tumors are more likely found
near the root of the mesentery
Benign solid tumors are more often found
in the periphery near the bowel
Cystic mass is found between the umbilicus and the
bladder. Incomplete regression of the urachus during
development
Urachal cyst
Encapsulated collection of urine, located outside kidney or bladder. Results from renal transplant, closed renal injury or surgical intervention, posterial urethral valves(PUV) obstruction.
May accumulate after a renal transplant due to an
anastomotic leak around the ureter
Urinoma
