Pulmonary paragonimiasis and tuberculosis are endemic in Asia, South America, and Africa. However, differential diagnosis among the diseases is difficult because they present with similar clinical symptoms and diagnostic features. Here, we report a case of pulmonary paragonimiasis that was identified using Ziehl-Neelsen stain after initially being assessed for pulmonary tuberculosis. Following anti-Paragonimus chemotherapy, the patient's symptoms, laboratory test results, and lung lesions improved. Thus, the identification of Paragonimus westermani using Ziehl-Neelsen stain can be considered in the diagnosis.

Magnification was 1,000× using oil immersion. (A) The initial chest X-ray in lateral decubitus position shows a significant amount of left pleural effusion (arrows). (B) Chest X-ray obtained 1 month later shows that the pleural effusion is resolved. Axial computed tomography (CT) scans reveal a focal area of consolidation containing tiny nodules in the upper left lobe (arrow) at the pulmonary window setting (A) and left pleural effusion (arrow) at the mediastinal window setting (C). (B, D) CT images obtained during the 3-month follow-up examination reveal improved lung lesions.
