Abstract:
Pneumomediastinum (PM) is an uncommon condition characterized by the presence of air in the mediastinum. It is associated with alveolar rupture that allows air to traverse along the bronchovascular bundle into the mediastinum. A review of the world medical literature identified 50 additional cases of PM and pneumopericardium (PC) associated with diabetic ketoacidosis (DKA). We report the occurrence of PM, PC, as well as epidural pneumatosis occurring simultaneously in a patient with DKA. Epidural pneumatosis in association with this metabolic derangement has not been previously described.
Insights
Pneumomediastinum and pneumopericardium are rare in diabetic ketoacidosis. This study reports a unique case of these conditions alongside epidural pneumatosis in a patient with diabetic ketoacidosis.
Area of Science:
- Medical Case Study
- Pulmonology
- Endocrinology
Background:
- Pneumomediastinum (PM) involves air in the mediastinum, often due to alveolar rupture.
- Pneumopericardium (PC) is a related condition.
- Diabetic ketoacidosis (DKA) is a serious complication of diabetes.
Observation:
- A patient with DKA presented with simultaneous pneumomediastinum, pneumopericardium, and epidural pneumatosis.
- This is the first reported instance of epidural pneumatosis occurring with DKA.
Findings:
- The study confirms the association between DKA and PM/PC.
- It introduces epidural pneumatosis as a novel, concurrent finding in DKA.
Implications:
- This case expands the understanding of rare intrathoracic and spinal air collections in DKA.
- Further research is warranted to explore the mechanisms and clinical significance of these combined findings.
