case_images: Right elbow MRI series showing a large heterogeneously enhancing and likely hemorrhagic mass with dilated vascular structures within the medial aspect of the distal biceps: axial view post-contrast (A), coronal view post-contrast (B), and sagittal view (C).

case_images: Magnetic resonance imaging (MRI) demonstrated a (6.5x4.9x8.5 cm) well-circumscribed, heterogeneously enhancing soft tissue mass within the medial aspect of the distal biceps with mass effect on the median nerve and brachial vasculature (Figure 1).
case_images: Right elbow MRI. No evidence of soft tissue mass or abnormal marrow signal: axial view (A), coronal view (B), and sagittal view (C).

case_images: A one-year post-excision MRI revealed enhancing soft tissue and intramuscular edema within the surgical bed, likely related to post-surgical changes, without evidence of solid nodular enhancing components to suggest recurrence (Figure 2).
