Case Report: Disseminated hydatid cyst: Unusual presentation and therapeutic challenges

Introduction: Cystic echinococcosis (CE), caused by Echinococcus granulosus sensu lato, is a parasitic disease prevalent in endemic regions. CE frequently leads to the formation of hydatid cysts in various organs, with the liver being the most commonly affected site. Involvement of the spleen has been rarely reported in the literature. Managing disseminated hydatid cyst disease presents significant diagnostic and therapeutic challenges. Case presentation: A 40-year-old female with a past medical history of hypothyroidism presented with sudden onset shortness of breath, dry cough, and chest pain for 3 days. She had a recent travel history to Egypt. Physical examination revealed mild right upper quadrant tenderness. Laboratory findings showed elevated white blood cell count with eosinophilia and increased inflammatory markers. Chest X-ray and pan-computed tomography (Pan-CT) scans identified multiple cystic lesions in the lung, liver and spleen. Serological tests confirmed the presence of anti-Echinococcus antibodies, leading to a diagnosis of disseminated hydatid cyst disease. The patient was managed medically and surgically by a multidisciplinary team. Conclusion: Disseminated hydatid cyst disease, though rare, presents complex diagnostic and management challenges. Timely recognition, supported by clinical, radiological, and serological assessments, is essential. Surgical intervention should be considered in a patient when multiple extrahepatic cysts are present, and rupture is evident, as this approach can significantly reduce patient morbidity and mitigate life-threatening complications.
