From: Evaluation of the solitary pulmonary nodule: size matters, but do not ignore the power of morphology
Axial chest CT scan, mediastinal window setting, in a 69-year-old woman with a previous history of gallbladder carcinoma. Because of increase in tumour markers, an 18F-FDG-PET-CT was ordered, showing a well delineated round nodule with absence of 18F-FDG-uptake. The internal aspect of the nodule shows small hypodense foci with negative Houndsfield units on measurement. The typical morphology, absence of uptake on 18F-FDG-PET and absence of evolution are consistent with a benign hamartoma
