Anaphylactic shock due to traumatic rupture of pulmonary hydatid cyst: Case report.

INTRODUCTION

Hydatid cyst is an infectious disease caused by « ECHINOCOCCUS GRANULOSIS », it can be asymptomatic or manifests depending on size, location, and relation with other organs, or by complication like rupture. This latter might occur spontaneously or post-traumatic, and it might manifest with an anaphylactic shock, a life-threatening situation.

IMPORTANCE

CASE PRESENTATION: A 30 years old man with no medical history was admitted to the emergency room after a car accident, on his admission, his Glasgow coma scale was 10/15 with a blood pressure of 80/30 mmHg, he was intubated and stabilized hemodynamically. The full-body CT scan showed no abnormalities except on the thoracic level where it showed a well-limited rounded formation with regular contours containing hydro-aeric level related to ruptured hydatid cyst. After ruling out the diagnosis of hemorrhagic, hypovolemic shock, the diagnosis of anaphylactic shock due to a post-traumatic rupture of the hydatid cyst was maintained.

CONCLUSION

Post-traumatic rupture of the hydatid cyst is a rare emergency that requires early diagnosis and management. Surgery remains the principal treatment of ruptured hydatid cyst. Anaphylactic shock is a life-threatening situation with various symptoms; epinephrine is the cornerstone for management of this type of shock.
