Imaging description Pulmonary hamartomas are the most common benign tumor in the lungs. They present as solitary, round, well-circumscribed soft tissue opacities in the lung parenchyma on CT imaging [1–3]. Areas of fat (60%) or calcification (26%) can be seen within the nodule . When areas of fat are identified in a nodule on CT imaging, the diagnosis of hamartoma can typically be made (Figures 22.1–22.3). Importance Hamartomas are benign lesions that do not need further workup or resection if they are asymptomatic. Since they usually present as an indeterminate nodule on the chest radiograph, a CT is often obtained to exclude malignancy. Recognition of fat within the nodule on CT will make the diagnosis of hamartoma and will exclude malignancy.
