Primary abdominal “egg-shelled” lesions with positive anti-echinococcus IgG antibody were misdiagnosed as echinococcosis.
Herein we report two cases with primary abdominal “egg-shelled” lesions were misdiagnosed as echinococcosis.
Enhanced CT scan and contrast-enhanced ultrasound scans are important for distinguishing echinococcosis disease from the other “egg-shelled” lesions. Surgical resection is the main treatment method for this disease. Minimally invasive surgery is recommended but should be performed by experienced surgical teams. Immunohistochemical examination is important for the pathologic diagnosis.
