      Abstract

      This report concerns two autopsy cases of severe motor and intellectual disabilities (SMID) who died of bronchospasms or tracheomalasia. One case had no anatomical change in the tracheal wall except for an endotracheal granuloma, while the other showed softening of the tracheal wall. Since patients with SMID have risk factors for bronchospasms and tracheomalasia, such as gastro-esophageal reflux, aspiration, and thoracic deformities, it is important that we suspect the possibility of these conditions, when we see the respiratory distress in cases of SMID.
