Abstract
Introduction and importance:
Although rare, the spontaneous rupture of a lung hydatid cyst or its perforation into the pleural cavity can give rise to an abrupt onset of symptoms, including cough, fever, hemoptysis (coughing up blood), and hypersensitivity reactions, and can ultimately lead to respiratory failure.
Case presentation:
A 12-year-old boy was brought to the emergency room with a loss of consciousness. Symptoms included tachypnea, fever, low blood pressure, and overall respiratory distress. After resuscitation, a chest X-ray revealed a distinct, well-defined round opacity located in the lower region of the right lung, leading to mediastinal displacement. After confirmation of the disease, the child was hospitalized in the ICU care and consequently underwent surgery. Treatment was successful and there was no recurrence on the follow-up.
Clinical discussion:
Studies have demonstrated that the right lower lobe of the lung is the most frequently affected area of the lung by hydatid cysts. Symptomatic and complicated hydatid cysts are a rare concept in children, and only a small percentage, are diagnosed in patients younger than 16 years. Surgery remains the preferred treatment for the majority of patients with pulmonary hydatid disease. It is important to note that combined surgery and chemotherapy represents the current gold standard in managing pulmonary hydatid cyst.
Conclusion:
Although anaphylactic shock caused by a ruptured lung hydatid cyst is rare, it should be taken into consideration by physicians as a differential diagnosis in patients who also have respiratory symptoms, particularly in endemic areas.
