A sharply demarcated ovoid lesion in the subcutaneous tissue with signal iso-intense to muscular tissue. Sagittal T1 image well demonstrates the superficial location in the upper thigh and the homogeneous hypo-intense signal comparable to muscle. Sagittal T2 FS well demonstrates the homogenous T2 hyperintensity of the lesion. Late series after IV contrast administration show mild enhancement of the lesion. Dynamic contrast enhancement curve showing a slow linear uptake of gadolinium (type 1 pattern).
