There is a well-circumscribed lobulated lesion centered on the left psoas muscle, homogeneous hypointense to the muscles on T1WI, hyperintense on T2WI, and T2 fat sat. The T1 fat sat postcontrast sequences show a prominent peripheral enhancement with centripetal fill-in on delayed phase.
MRI features are suggestive of a soft tissue hemangioma of intramuscular location on the left psoas muscle.
