Tumor-like disorder of the brachial plexus region in a patient with hemophilia: A case report

Figure 1 Magnetic resonance images of the left upper limb. Sagittal and coronal views of T2-weighted images showed a focal mass on left coracobrachialis muscle (white arrow).

Figure 2  Histopathological examination of the resected mass showed inflammatory infiltration with hemosiderin pigments and fibrosis (hematoxylin and eosin stain, × 100).

Figure 3 Intraoperative findings of the patient. A: An organized mass was exposed prior to excision (black arrow); B: Brachial plexus neurolysis was performed after the mass resection; C: The cut surface of the resected specimen indicated an organized chronic hematoma rather than a neoplasm.

Figure 4  A 12 mo follow-up assessment demonstrated definite improvement in the left shoulder abduction, elbow flexion and grip strength after successful surgery.
