case_images: (A) CT angiogram (soft tissue window) and (B) CT angiogram (lung window) showing anterior mediastinal mass, hilar adenopathy, bilateral lung nodules. (C-E) VATS pathology specimen showing areas of non-necrotizing and poorly-formed necrotizing granulomas without evidence of malignancy. (F) PET-CT showing FDG-avid anterior mediastinal mass and diffuse mildly FDG-avid nodules throughout lung parenchyma.

case_images: Computed tomography (CT) showed an anterior mediastinal mass with soft-tissue nodules throughout the lungs with bilateral perihilar adenopathy, suspicious for diffuse metastatic disease (Figure 1). Pathology demonstrated areas of non-necrotizing and poorly formed necrotizing granulomas without evidence of malignancy (Figure 1). She underwent PET-CT, which showed a large fluorodeoxyglucose-avid anterior mediastinal mass and diffuse mildly fluorodeoxyglucose-avid nodules throughout the lung parenchyma (Figure 1).
