Q

Rectus muscles are seen as a biconvex muscle

group delineated by the

A

20
Q

Extrahepatic loculated collections of bile. May develop because of trauma, GB disease, or biliary surgery

A

biloma abscess

21
Q

Malignant solid tumors are more likely found

A

near the root of the mesentery

22
Q

Benign solid tumors are more often found

A

in the periphery near the bowel

23
Q

Cystic mass is found between the umbilicus and the
bladder. Incomplete regression of the urachus during
development

A

Urachal cyst

24
Q

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

25
Most common sites of peritoneal metastases...
ovaries, stomach, colon
26
represents a mass infiltrating the mesenteric leaves and encasing the SMA.
"Sandwich sign"----lymphoma
27
most often occur in middle-aged men as the result of exposure to asbestos
peritoneal and omental mesotheliomas
28
Collection of fluid that occurs after surgery in the | pelvis, retroperitoneum, or recess cavities. Surgeries include--renal transplant, GYN surgery, vascular surgery.
Lymphoceles
29
2 longitudinal muscles that extend from the xiphoid process to the pubic bone.
rectus abdominus muscles
30
these sheaths join to make the linea alba
rectus sheath
31
hematomas superior to the arcuate line...
will not move across the midline
32
hematomas inferior to the arcuate line...
will extend into the space of retzius/retropubic space
33
Occur as the result of direct blunt trauma, pregnancy, cardiovascular and degenerative muscle diseases, surgical injury, anticoagulation therapy, steroids, or extreme exercise. Lab values may show decreased hematocrit levels
Extraperitoneal hematoma
34
most common area for an abdominal hernia
inguinal
35
Protrusion of a peritoneal-lined sac through | a defect in the weakened abdominal wall
abdominal hernia
36
➢ Demonstration of an abdominal wall defect ➢ Presence of bowel loops or mesenteric fat in a lesion ➢ Exaggeration of the lesion with strain (Valsalva maneuver) ➢ Reducibility of the lesion by gentle pressure sonographically indicate what?
hernia
