Massive subcutaneous emphysema and complete resorption images detected on [18F]-FDG PET/CT.

Abstract

Subcutaneous emphysema may occur iatrogenically, spontaneously, or post-traumatically as a result of free air passage under the skin from the respiratory tract or gastrointestinal tract. In this case, we present the typical appearance of a case of massive subcutaneous emphysema observed on [18F]-FDG PET/CT for metabolic characterization due to a massive lesion in the lung and the images of complete resorption after seven months.
