Hepatic adenoma mimicking liver hydatid disease: Case report

Abstract

Case Report: A 34-year-old female obese patient, married, who lived in Abreu e Lima (PE), with a history of moderate abdominal pain in the right flank and weight loss (10 kg in 7 months): She visited Para State two years ago and denied having used any oral hormonal contraceptive. Imaging exams showed big cystic and multiloculated formations in the liver, with the largest being of 16 x 13 x 14cm. Due to the aspects of the image, epidemiology and the symptoms of the patient, a diagnosis of hydatid cyst was considered, and the patient was treated with praziquantel and albendazole. The surgical procedure was proposed based on the recommendations of the WHO for the treatment of hydatic disease, even without the result of the serology test. Operatory findings showed cystic lesions with a pasty and amorphous content, of yellow-green aspect. The surgical specimen evaluation showed a hepatic adenoma with necrotic tissue and central cavitation. The diagnosis was confirmed by immunohistochemistry. The serology test for echinococcosis was negative. The patient had no further complications and was discharged in good clinical condition. Conclusion: We presented rich iconographic information of all aspects of this case and reviewed all the differential diagnoses for cystic lesions of the liver.
