Abstract

Hematoma on the thoracic wall is very rare. We describe here a 63-year-old man with a huge chest wall hematoma and the man had no history of trauma. The patient was found to have a large mass located subjacent to the inferior angle of the right scapula area and the CT and MRI findings were similar to those of an elastofibroma dorsi. We describe the CT and MRI findings of this hematoma and how to make the differential diagnosis from elastofibroma dorsi.

Figure

• 

  Fig. 1 A. The axial noncontrast chest CT scan shows a poorly defined soft tissue mass (arrows) on the posterolateral aspect of the chest wall with an attenuation value similar to that of the neighboring muscle and suspicious linear interspersed hypodense areas. B. The axial postcontrast CT demonstrates no remarkable enhancement of the mass (arrows).

• 

  Fig. 2 A. The coronal T2-weighted MR image shows the soft tissue mass in the right subscapular region with heterogeneous signal intensity that included low signal intensity and high signal intensity linear strands. There is an associated peripheral dark signal rim (arrows). B. The fat suppressed sagittal T2-weighted MR image reveals heterogeneous hyperintensity (arrow). C. The coronal T1-weighted MR image shows an intermediate signal intensity mass lesion (arrow) in the right chest wall, with interspersed lines of high signal. D. The fat suppressed coronal T1-weighted MR image after contrast injection shows peripheral rim enhancement without central enhancement (arrow).

• 

  Fig. 3 The microscopic findings show a mixture of fibrin, several hemosiderin-laden macrophages and blood clots. Neither elastofibroma nor a fat component was present (H & E ×200).
