In the posterolateral compartment of the left calf, is visible lesion with lobulated margins, adhering to the transverse and posterior intermuscular septum, with lobulated spurs surrounding the peroneal diaphysis posteriorly. This lesion that compresses the neurovascular axis shows low signal intensity in T1 weighted sequences and high signal in T2 weighted sequences and in those with saturation of the adipose tissue. After IV contrast, intense enhancement is appreciated with intra-tumoral cystic degeneration.
