title: Sarcomatoid carcinoma of the lung mimics aspergilloma on ¹⁸F-FDG PET/CT.
abstract: Primary PSC in the lung is a rare malignant cancer that represents a particularly aggressive subtype of non-small cell lung carcinomas (NSCLC) containing sarcoma or sarcoma-like components with spindle or giant cell features. The medical literature referring to imaging characteristics by fluorine-18-fluorodeoxyglucose (¹⁸F-FDG) positron emission tomography/computed tomography (PET/CT) of these tumors is very limited. We present a case of PSC with air crescent and halo signs that resemble aspergilloma on the ¹⁸F-FDG PET/CT, scan.
