      (A) Chest computed tomography (CT) was performed in a 75 year old man who complained of dyspnoea. CT revealed a 43 mm diameter left subclavian artery aneurysm (arrow). As kidney cancer was also suspected in this patient, 18F-fluorodeoxyglucose (18FFDG) positron emission tomography CT was performed, which revealed unexpected focal and intense 18FFDG uptake of the suspected aneurysm. (B) Magnetic resonance imaging showed a well encapsulated heterogeneous spherical mass (arrow), hyperintense on T2 attenuated images, impinging on the subclavian artery, which allowed for a diagnosis of pleural schwannoma. This rare tumour should be kept in mind for differential diagnosis of an intrathoracic peri-arterial lesion.
