In supine patients, infected fluid from the right iliac fossa may ascend in the paracolic gutter to enter the lesser sac. In patients nursed in a sitting position, fluid from the stomach, duodenum, or gallbladder may run down the paracolic gutter to collect in the right iliac fossa or pelvis. This may mimic acute appendicitis or form a pelvic ...
In case of appendicitis, signs such as fever, positive psoas sign, migration of pain from umbilicus to the right iliac fossa increases the likelihood of the disease; while signs such as vomiting before the pain reduces its likelihood to occur. [2]

It crosses the hip joint to insert on the lesser trochanter of the femur. [1] The iliopsoas is classified as an "anterior hip muscle" or "inner hip muscle". [2] The psoas minor does contribute to the ...
