Diagnostic Challenges During Pandemic: A Case Report

Hydatid cyst is an infection caused by the parasite Echinococcus granulosus, which is seen endemic in animal husbandry areas. Due to the heavy burden on physicians during the pandemics, diseases other than COVID-19 took a back seat during the differential diagnosis of patients. Hydatid cyst is located in the bone at a rate of 1-4%. The symptoms and imaging features of the cyst located in the bone are not specific, thus they are less likely to be considered in the differential diagnosis of extremity lesions. The absence of a specific clinical picture and the lack of high sensitivity of the indirect hemagglutination test bring radiological evaluations to the fore in diagnosis. In this case report, we shared diagnostic and treatment process of a patient-who was first admitted to the hospital with edema, pain and fever in the leg, was diagnosed with multisystem inflammatory syndrome in children (MIS-C) later diagnosed hydatid cyst with lung and bone involvement.
