Heterogeneously hypoechoic collection with multiple foci of gas, measuring 8.3 x 3.2 cm noted in the right psoas muscle.
Case Discussion
Psoas muscle abscess and fluid collections are located in the retrofascial space rather than in the retroperitoneal space because the psoas muscles are located in the iliopsoas compartment posterior to the transversalis fascia, which is the posterior boundary of the retroperitoneum.
