CT images of progression of hepatic cyst rupture. a CT image 1 month before presentation to our hospital. The largest cyst showed an irregularly shaped wall on the ventral side (above, yellow arrows). At that time, the caudal part of the cyst kept circular (below). Some ascitic fluid was found around the spleen. b CT image on arrival to our hospital. Volume of the irregularly shaped cyst had obviously decreased (red arrows) and was present within a relatively high dense lesion (red circle)

She had a history of conservative treatment for a spontaneous NLC rupture 1 month previously in another hospital (Fig. 1a). The largest cyst was found on the lateral segment; it exhibited an irregularly shaped surface and was present within a partially high dense lesion (Fig. 1b). The cyst volume had obviously decreased during the 1-month period before presentation to our hospital (Fig. 1, below).
Perforation lesion of hepatic cyst. The perforation lesion was on the ventral side of the cyst. The lesion was approximately 3 cm, and the cyst wall was fibrous

During the operation, we found the perforation site on the ventral side of the cyst (Fig. 2).
Pathological examination of cyst wall. Only fibrous connective tissue covered with simple cuboidal epithelium was observed; no evidence of malignancy was present
