A 50-year-old-smoker patient with no medical history has developed an intrathoracic mass. A CT scan has been firstly performed where a 6-cm-isodense-intrathoracic mass has been found with regular contours associated to other nods with regular contours. In addition, centimetric mediastinal lymph nods have been identified. There was no other extra-thoracic localizations. Besides this atypical presentation, we have realized a 18FDG PET/CT showed a significant intense uptake of 18FDG of the mass (SUVmax=6,5) and a significant intense uptake of 18 FDG (SUVmax=8,1) of the other intrathoracic nods and of the lymph nods (SUVmax=5,2). There was no other extra-thoracic localizations. So we have performed a biopsy of the mass and it has highlighted “a growing of fusiform cell arranged in a beam associated to nuclear palisading pattern and the positivity of S-100 making the diagnosis of schwnnoma” and an endobronchial ultrasound biopsy for lymph nodes that has showed “inflammation and the absence of tumoral cells.”. After surger, the definitive histopathology confirmed the diagnosis of benign schwannoma.
