Mediastinal Castleman's disease: a missed pre-operative diagnosis?

Mediastinal lymphadenopathy is common and usually requires further evaluation with computed tomography (CT).

Intense enhancement following intravenous contrast medium would indicate the vascularity of the lesion and add weight to the diagnosis.
