Costochondritis does not present with increased bilateral lung texture. The site of costochondritis is the costal cartilage, whereas increased bilateral lung texture is a common pathologic finding on chest radiographs. Increased bilateral lung texture is most commonly seen with intrapulmonary diseases (e.g., chronic bronchitis, interstitial lung disease, bronchiectasis) and also in smokers. Chest X-ray of costochondritis usually shows scattered patchy calcification, localized osteoporosis, and swelling of the surrounding soft tissues. If a patient with costochondritis has increased texture in both lungs, it should be considered unrelated to costochondritis, and it is recommended that further related examinations, such as chest CT, be performed to determine the cause of the disease and then follow up under the guidance of a physician.
