Radiological findings of lung lesions detected in three patients with I-DiPO and three patients with S-DiPO. Three patients with I-DiPO had low (calcified total score = 3; a, b, Patient 3), medium (score = 4; c, d, Patient 10), and high (score = 5; e, f, Patient 28) levels of calcified lesions. The calcified total score represents the sum of grades from three assessment items for calcified lesions: fine calcified nodules, calcified short lines, and calcified branching structures. Three patients with S-DiPO had ossified lesions associated with IP (g, h, Patient 12) and ossified lesions associated with Af and IP (i, j, Patient 31; k, l, Patient 24). (a, c, e, g, i, k) Chest radiographs; (b, d, f, h, j, l) computed tomography horizontal sections under lung window settings. Af Atrial fibrillation, I-DiPO idiopathic diffuse pulmonary ossification, IP interstitial pneumonia, S-DiPO secondary diffuse pulmonary ossification.
