Dynamic magnetic resonance imaging features of cavernous hemangioma in the manubrium: A case report

Figure 1 Chest imaging. A: Axial; B: Coronal thoracic computed tomographic scans showing an expansile and osteolytic mass in the manubrium with cortical destruction.

Figure 2 Thoracic magnetic resonance imaging. A: Slightly heterogeneous hyperintensity in the sternal mass on T2WI; B: Isointensity on T1WI. Contrast-enhanced thoracic magnetic resonance imaging. C: Peripheral nodular enhancement in the early phase; D: Progressive centripetal fill-in in the delayed phase.

Figure 3 Macroscopic appearance of the resected tumor. The specimen revealed a hypervascular appearance.

Figure 4 Histologic findings. Large, dilated, blood-filled vessels lined by flattened endothelium within the sternal manubrium tissue (hematoxylin and eosin stain, magnification × 100).
