1. Enhanced chest CT
Enhanced chest CT would be an appropriate next step in the evaluation of this patient’s chest wall abnormalities. Chest MRI would also be an appropriate choice but was not one of the listed options. 18FDG-PET could prove useful at some point in this patient’s evaluation, but is premature as the use of 18FDG-PET is often more rewarding following anatomic characterization. 68Ga-PSMA-11 PET/CT is a modality typically used for assessment for prostate carcinoma. 68Ga-pentixafor PET/CT is a modality which may be employed for endocrinologic disturbances, notably Cushing syndrome or aldosterone-secreting tumors. 68Ga-DOTA-FAPI-04 PET/CT is a modality that employs fibroblast activation protein inhibitors (FAPI) labeled with radionuclides that be used for the diagnosis and treatment of various malignancies.
The patient underwent enhanced chest CT (Figure 3).
