Nodular pulmonary amyloidosis with unusual, widespread lung cysts

Abstract

A 49-year-old Chinese woman was referred to our hospital for management of multiple lung nodules, which were incidentally detected on routine chest radiography. Chest computed tomography (CT) confirmed the presence of multiple pulmonary nodules and lung cysts. The lung cysts were located apart from the pulmonary nodules. CT-guided biopsy of the pulmonary nodule specimens confirmed the diagnosis of nodular pulmonary amyloidosis. While cavitation of existing pulmonary amyloid nodules is a well-recognised feature of nodular pulmonary amyloidosis, widespread lung cysts located apart from pulmonary nodules is rare.
