Anaphylaxis triggered by a hidden threat: A rare hydatid disease case report.

INTRODUCTION AND

IMPORTANCE

Hydatid disease, caused by Echinococcus granulosus, is a zoonotic infection prevalent in specific regions, including Tunisia. Complications are rare but potentially life-threatening. This case report highlights the significance of early diagnosis and intervention in a unique case where anaphylaxis resulted from minor abdominal trauma in a 17-year-old male with an undiagnosed hydatid cyst.

CASE REPORT: The patient arrived at the emergency department with syncope and hypotension after a classroom accident. Physical examination showed an urticarial rash and abdominal tenderness. Anaphylactic shock was diagnosed and promptly treated. A computed tomography scan confirmed a ruptured liver hydatid cyst. The patient received anthelmintic treatment and underwent conservative surgical management. Intraoperatively, a second anaphylactic shock occurred and was promptly treated. The post-operative course was uneventful, and histopathological analysis identified Echinococcus granulosus.

CLINICAL DISCUSSION: This case emphasizes the importance of recognizing hydatid disease as a potential cause of anaphylaxis post-trauma, even in asymptomatic patients. Early diagnosis through imaging is crucial for prompt intervention. Surgical management should be considered, with conservative approaches favored in acute cases. Post-surgical albendazole treatment is essential to prevent recurrence.

CONCLUSION

This report serves as a valuable reference for healthcare professionals, highlighting the need for heightened clinical suspicion in cases like this. It underscores the significance of considering hydatid cyst rupture in the differential diagnosis of anaphylaxis following blunt trauma. Awareness among pediatricians, emergency physicians, and primary care providers can lead to early diagnosis and better patient outcomes, preventing severe complications or fatalities associated with this rare condition.
