Chronic Expanding Hematoma in the Extremities: A Clinical Problem of Adhesion to the Surrounding Tissues

Figure 2

69-year-old female with a chronic expanding hematoma in the deep thigh. MRI shows a huge lesion with cystic features ((a–c) axial image; (d-e) coronal image; (f) sagittal image). The sciatic nerve where it branches into the tibial nerve and the common peroneal nerve is not obvious on axial section. A yellow circle indicates the area where the nerve is supposed to exist (a). MRI shows heterogeneous low to slightly intermediate intensity on T1-weighted imaging (a, d). Heterogeneous low to high signal intensity is seen on T2-weighted (b, e) and fat-suppression T2-weighted imaging (c, f). A fibrous cystic wall is visible after removal of the hemorrhagic coagulation material (g).
