A Retained Wooden Foreign Body in the Lung Parenchyma Presenting as Aspergiloma

Despite advances in imaging techniques, the detection of retained wooden foreign bodies remains a difficult and challenging task. The detection of wood is especially important because it may serve as a nidus for superimposed infection. The initial examination may mimic malignancy. We report a rare case of retained wooden foreign body in the lung parenchyma, which was found on CXR and CT as a thick-walled cavity. Surgical resection was performed and the wooden particle was removed. Review of literature shows that wooden foreign bodies in the lung parenchyma are quite rare and they may present with a wide variety of density. We conclude that foreign body should be considered in the differential diagnosis of unusual lung opacity.
