A 20-year-old female patient presented with two masses located in the left liver.In this patient, a computed tomography(CT) scan revealed a hypodense mass and a second well-defined mass with a calcified nodule in the left hepatic lobe.No enhancements were apparent in or around the masses.A laparotomy was performed due to the patient's symptoms, namely, the atypical CT findings and a risk of rupture of the subcapsular lesion.The operation revealed two masses in the left hepatic lobe and a left liver resection was subsequently performed.One of the masses involved segment Ⅲ and the other mass was located in segment Ⅳ.The histopathologic findings supported a diagnosis of collagenous nodule mixed simple cyst and hemangioma.A diagnosis of collagenous nodule mixed simple hepatic cyst is extremely rare and radiologically mimics a teratoma, hepatolithiasis, parasitic cyst, or hemangioma.Although hepatic hemangiomas are the most common benign tumors found in the liver, the present case showed atypical radiographic features.
