[Benign schwannoma with high uptake of 18 fluorodeoxglucose (PET-Scan)].
BACKGROUND
In patients with a previous history of malignancy, the occurrence of a mediastinal mass with significant uptake of 18 Fluorodeoxyglucose on a PET-scan may lead to biopsy or resection.


METHODS
We report the case of a posterior mediastinal mass, with significant uptake of 18 Fluorodeoxyglucose on PET- scan, in a patient with a previous history of testicular seminoma. The lesion was actually a benign schwannoma.


CONCLUSIONS
In the case of a mediastinal mass with conventional imaging being in favour of a neurogenic tumour a PET scan cannot confirm benignity or malignancy.
