Fat embolism syndrome in Duchenne muscular dystrophy: an underdiagnosed complication.

INTRODUCTION

Fat embolism syndrome (FES) is a rare but potentially life-threatening complication of long bone fractures, typically described in high-energy trauma. In patients with Duchenne Muscular Dystrophy (DMD), even minor trauma can result in FES, owing to long-standing osteoporosis and prolonged corticosteroid therapy, and the recognition can be challenging.

MATERIALS AND

METHODS

We report a case series of three non-ambulatory patients with DMD who developed fat embolism syndrome following traumatic events. Clinical presentation, diagnostic challenges, and management strategies were retrospectively analyzed.

RESULTS

All three patients presented with features consistent with FES, with diagnostic difficulties related to atypical mechanisms of injury and overlapping neuromuscular symptoms. Timely supportive management led to favorable clinical outcomes in all cases.

DISCUSSION: These cases illustrate the critical need to closely consider FES in DMD patients who experience unexplained respiratory or neurological decline following trauma.

CONCLUSION

Prompt recognition and a multidisciplinary approach are critical to minimizing morbidity and supporting recovery.
