Homogenous internal echoes. Image of a 72-year-old woman with a peripheral consolidation lesion over the right lower lung lobe by chest radiography ((b) black arrow) with parrot chlamydia pneumonia identified by mNGS. EBUS demonstrated homogeneous internal echoes without margins (a). The particles displayed a formation of concentric circles around the echo probe, and entire images exhibited a sense of gradation. The particles lengthened to form a very short arc of the circumference, particularly in the outer part (white arrow).
