Unicentric Castleman's Disease Arising from an Intrapulmonary Lymph Node
Figure 2
Dynamic CT scans of the chest, in plane (a), arterial (b), portal in-flow (c), and equilibrium (d), show a well-defined, lobulated, soft-tissue mass with small calcifications in the right lower lobe. The periphery of the mass was strongly enhanced in the arterial phase, and the parenchyma of the mass was heterogeneously enhanced in the portal in-flow to equilibrium phase.
