Diagnosis With Brief Discussion

Diagnosis
IgG4 related lung disease
Radiologic Findings
Chest CT shows two well-enhancing nodular lesions in RLL superior and posterobasal segment. Pleura-based nodule is also seen in RUL. There is mesenteric fat infiltration on abdomen CT.
The patient underwent VATS resection and laparoscopic mesenteric resection for diagnosis.
The pathologic report revealed numerous IgG4-positive plasma cells and it was confirmed as IgG4 related lung disease.
Brief Review
Recently, increasing attention has been drawn to IgG4 related disease. IgG4 related lung disease is a spectrum of systemic IgG4 related disease characterized by extensive IgG4-positive plasma cells and T-lymphocyte infiltration of various organs.
The radiologic features of IgG4 related lung disease could be classified into four types : solid nodular, round-shaped GGO, alveolar interstitial, and bronchovascular. Differential diagnosis varies among radiologic features: lung cancer (solid nodular type), adenocarcinoma (round-shaped GGO), interstitial pneumonia (alveolar interstitial), sarcoidosis or lymphoplroliferative disease (bronchovascular).
Complete surgical resection is recommended for both diagnosis and treatment. However, some reports that IgG4 related lung disease response to corticosteroid therapy.
