Fig. 1 Chest PA shows nodular increased opacity in left upper lung field.
Fig. 2-6 (Images taken after 2 weeks) Chest PA shows decrease in extent of previous nodular opacity in left upper lung field, but there is newly appeared increased opacity at left hilar region. Chest CT shows subpleural consolidation with peripheral ground-glass opacity and adjacent pleural effusion in left upper lobe apicoposterior segment, and another consolidation at the superior segment of left lower lobe with linear density extend to the pleural surface.
Fig. 6-10 (Images taken after 4 weeks of initial study) Chest CT shows decrease in extent of previous consolidation in left upper lobe apicoposterior segment, but increase in extent of consolidation at the superior segment of left lower lobe with newly appeared focal air-bubble.

Brief Review
Pulmonary paragonimiasis is a parasitic infection caused by trematodes (or lung flukes) of the genus Paragonimus. This disease is caused by ingestion of a raw or incompletely cooked freshwater crab or crayfish infected with the metacercaria. Paragonimus excyst in the small intestine, and the larvae penetrate the intestinal wall and enter the peritoneal space. Next they penetrate the diaphragm and pleura and enter the lung in 3
