PET Scan

• Although PET-CT scans are not indicated for histoplasmosis, they may often be ordered to rule out malignancy.
• Unfortunately, PET scans have poor specificity when it comes to differentiating histoplasmosis and lung adenocarcinoma.
• Although histoplasmosis may cause calcified nodules, many nodules never calcify, or calcify partially and PET scans demonstrate increased uptake in these lesions.
