Plain radiography and computed tomography. A striated calcification on the right side of the first and second lumbar vertebrates was noted (arrow) in abdominal plain radiography (A,B). Computed tomography revealed a homogenous mass with central calcification (arrow) in the swollen psoas muscle (C). After contrast enhancement, the mass presented a dumbbell-like shape, extending to the intervertebral foramen (D).
