Description
Takayuki Takimoto and four co-authors report a 2026 imaging study of a rare scarring lung disease called idiopathic pleuroparenchymal fibroelastosis. The disease stiffens the upper lobes and restricts breathing for reasons that remain poorly understood. The team wondered whether stiff joints in the chest cage itself help limit how much the thorax can move.
Seventeen patients with the disease and fifteen with other lung diseases had CT scans taken while breathing in and out. Joint abnormalities, mostly abnormal calcium deposits near the breastbone joints, appeared in fourteen of the seventeen patients. Half showed clearly reduced chest motion, and every patient with reduced motion had joint changes. Chest motion tracked lung volume change closely, suggesting the cage, not only the lung, restricts breathing.
