Extensive epidural pneumatosis and pneumomediastinum combined with diabetic ketoacidosis

KEY CLINICAL MESSAGE: Epidural pneumatosis and pneumomediastinum are rare, benign complications of diabetic ketoacidosis. As they can mimic serious conditions including esophageal rupture, diagnostic evaluation, and attentive monitoring are crucial. ABSTRACT: Diabetic ketoacidosis can rarely present with epidural pneumatosis and pneumomediastinum, possibly due to forceful vomiting and Kussmaul breathing. Recognizing these pneumocomplications is crucial, as they can mimic severe conditions, including esophageal rupture. Consequently, diagnostic workup and vigilant monitoring are critical, even though these pneumocomplications are typically benign and self‐resolving.
