Objective: The purpose of this article is to describe the sonographic findings of muscle infarction in patients with diabetes with MR imaging, CT, and pathologic correlation.
Conclusion: Sonographic findings of diabetic muscle infarction include internal linear echogenic structures coursing through the lesion; an absence of internal motion or swirling of fluid with transducer pressure; and a lack of a predominately anechoic area. We believe that these sonographic characteristics may help differentiate diabetic muscle infarction from abscess or necrotic tumor. Additional study involving direct sonographic comparison of these entities is needed to establish the role of sonography in diagnosis of diabetic muscle infarction.
