File:Myotonic dystrophy - type 1 (Radiopaedia 66131).png

Summary:

• Radiopaedia case ID: 66131
• Image ID: 46278564
• Study findings: There are 12 pairs of ribs. The ribs are thin. The thorax is small and bell-shaped pronounced due to poor respiratory effort. Feeding tube terminates in the stomach. Cardiothymic silhouette appears enlarged due to low lung volumes and poor inspiratory effort and small thorax. Opacity in right upper and mid zone is most likely the thymus. No effusion or pneumothorax. Non-specific non-obstructive bowel gas pattern is seen throughout the abdomen. Symmetric abduction at the hips and well-positioned infant without restraining suggests diffuse hypotonia. Comment: Findings are highly suggestive of neonatal neuromuscular disease; differentials include: myotonic dystrophy, spinal muscular atrophy, myopathy among others.
