case_images: A 23-year-old female patient was referred for treatment of a posterior mediastinal tumour to the left of the spinal column that was found incidentally on a chest CT during physical examination one month prior (Figure 1 A/B). Posteroanterior chest x-ray film revealed revealed a left posterior mediastinum soft-tissue mass (white arrow) (Figure 1 C), All laboratory examination results were almost within normal limits. Chest X-ray 12 hours after surgery revealed severe interstitial and alveolar oedema (Figure 1D).
case_images: The microscopic findings show characteristic arrangement in well-defined nests (zellballen) bound by a delicate fibrovascular stroma. The tumor cells vary in size and shape and have a finely granular basophilic or amphiphilic cytoplasm with mild cellular atypia.
