Right-sided pulmonary stigmata are old lesions that remain after the inflammatory reaction in the lung has completely healed, just like scars that remain after the wound has healed from a skin injury. It is mainly seen in inflammation of the lung caused by specific pathogens such as Staphylococcus aureus, bacteria such as Klebsiella, and specific Mycobacterium tuberculosis infections. It often presents with fibrotic, calcified lesions, which usually do not have any clinical symptoms and do not require special treatment. It only needs to be closely observed and followed up at any time, mainly by taking X-rays, CT or MRI of both lungs to clarify.
