Fig. 1From: Mediastinal follicular dendritic cell sarcoma: a rare, potentially under-recognized, and often misdiagnosed diseaseAxial CT of case 1 shows a mass with distinct border in the right upper anterior mediastinum (a), which presents an obviously heterogeneous enrichment after enhancement (b). Axial plain (c) and enhanced (d) CT of case 2 reveal that in the right posterior mediastinum, there is a giant lobulated shadow with moderately heterogeneous enhancement. Sagittal (e) and axial (f) positron emission tomography and CT of case 3 indicate a mass in the middle mediastinum with avid fluorodeoxyglucose uptake (SUVmax = 11.95)Back to article page
