Imaging findings
Chest CT of a patient with a 30-year active smoking history showed multiple scattered, partially cavitary micronodules with varying wall thickness, small cavitary lesions, an apical-basal gradient, and classic sparing of the costophrenic angles and lung bases.
Key takeaways
Pulmonary Langerhans Cell Histiocytosis (PLCH) typically presents in smokers with characteristic imaging features including cavitary nodules, often with an apical-basal predominance and sparing of the lung bases and costophrenic angles.
