A 79-year-old man developed a cough and a right-sided pleural effusion after receiving the fourth COVID-19 vaccination; therefore, thoracentesis was performed. The pleural effusion was exudative and had a high adenosine deaminase (ADA) level. A diagnosis could not be reached, and a pleural biopsy was performed. Histopathology showed IgG4-positive plasma cells and lymphocytic infiltration, and a diagnosis of pleurisy caused by an IgG4-related disease was made. After starting steroid treatment, the pleural effusion and subjective symptoms improved. In addition to tuberculous pleurisy, we believe that pleurisy caused by IgG4-related diseases should be considered in cases of pleural effusion with high ADA levels.
