Ultrasonography Facilitates the Diagnosis of Traumatic Iliopsoas Hemorrhage: A Report of Two Cases with Different Patterns.

ABSTRACT

We report two cases of traumatic iliopsoas hemorrhage, without hemoperitoneum, initially detected by ultrasound. Flexion hip contracture in the first case and incomplete femoral nerve palsy in the second case alerted the sonographer to the possibility of traumatic iliopsoas hemorrhage. The first case involved a 54-year-old man who complained of progressive right flank pain and difficulty in walking after falling to the ground. The second case involved a 34-year-old man who complained of severe lower back pain and numbness and weakness of the left leg after a motorcycle accident. In both cases, iliopsoas hemorrhage was confirmed on subsequent multidetector computed tomography.
