A 47-year-old previous healthy man presented to the emergency department due to a 2-day course of fever and rigor. He denied having any systemic illness and habitual drinking or illicit drug abuse. Physical examinations were unremarkable. Laboratory data showed white blood cell count of 18,500 μL, C-reactive protein of 18.6 mg/dL, alanine aminotransferase of 76 U/L, and bilirubin of 1.6 mg/dL. The urine analysis and chest radiography were normal.

Contrast-enhanced computed tomography (CT) of the abdomen showed two cystic lesions over segment 8 and 2 respectively (Figure 1A and 1B, white arrows). To confirm the nature of these cystic lesions, magnetic resonance imaging (MRI) with gadolinium enhancement was performed.
