Shoulder lipoblastoma: magnetic resonance imaging characteristics.

: The authors describe the magnetic resonance imaging (MRI) characteristics of lipoblastoma of the shoulder in an infant. The appearance of the lesion in MRI scans correlated well with the pathological observation of lobules of immature adipose tissue surrounding masses of myxoid tissue. However, the MRI study of lipoblastoma is nonspecific, and the results of other radiologic modalities, such as plain radiography, ultrasonography and computed tomography, are essential for a confident diagnosis.
