Multiple cystic pulmonary metastases of pancreas cancer masquerading as pulmonary Langerhans cell histiocytosis: a case report

Abstract

Aim of the study: to evaluate the possibilities of differential diagnosis of cystic metastases of pancreatic cancer in the lungs and pulmonary Langerhans cell histiocytosis (PLCH)Materials and methods. Multiple cysts were visualized in the patient's lungs, which had thin and thick walls. We visualized in the patient's lung several small nodes with random distribution. These changes were located mainly in the upper and middle sections of the lungs, with the presence of several cysts and nodes near the costal-diaphragmatic angles. The differential diagnosis is formed from metastatic lung disease and pulmonary Langerhans cell histiocytosis. Morphological verification of changes in the lungs confirmed metastatic lung disease.Conclusion. A careful assessment of the thickness of the walls of cysts and the type of location of nodes in the patient's lungs made it possible to diagnose metastatic lung disease according to CT scans.
