Tension Viscerothorax in a Patient with Missed Traumatic Diaphragmatic Hernia. A Case Report.

Background: Diaphragmatic hernias occurring post trauma are a challenge to diagnose early especially when they follow blunt trauma. Many of those diagnosed early occur in penetrating thoraco-abdominal trauma which necessitates emergency exploration where the diagnosis is picked. Rarity of traumatic diaphragmatic hernia coupled with poor sensitivity of easily available imaging modalities makes it a big challenge to pick up this potentially fatal pathology. Case presentation: We present a rare case of tension viscerothorax in a young man who had presented to the emergency department at a provincial hospital of Rwanda three days before the second consultation where the chest x-ray was interpreted as normal and later as a pneumothorax before the diagnosis and treatment of tension viscerothorax could be made. Conclusion: Viscerothorax is an elusive diagnosis which when missed can complicate to strangulation of hernia contents or tension viscerothorax which carry a high mortality.
