Figure 1: (A-C) Periapical cyst. Intraoral periapical radiograph (A) shows a well-circumscribed radiolucent periapical lesion (arrow) with a partial sclerotic border, measuring more than 1 cm in diameter. USG with color Doppler and power Doppler (B) shows a hypoechoic, well-contoured cavity (arrow) with no evidence of internal vasculature on color and power Doppler examinations. H and E stained section shows the presence of an epithelial lining (arrow) with underlying dense fibrocellular connective tissue stroma (arrowhead)
