We report a case of a huge hepatic cyst which rapidly regrew after spontaneous rupture. Case Report: A 74-year-old male underwent further examination and follow-up of a huge hepatic cyst which was first detected at annual health check. On his first visit, the cyst was 10×9 cm in size. During the first 7 years of follow-up, the cyst gradually grew to 18×14 cm. Eight years after his first visit, ultrasonography showed that the huge hepatic cyst was without intracystic echogenic content. However, nine days after that, a computed tomography (CT) scan revealed that the cyst had nearly disappeared with remnant minimal cystic fluid and ascites although the patient was asymptomatic. Subsequently, within one month, the patient complained of back pain, and another CT scan showed that the cyst rapidly regrew to 13×10 cm in size. The cyst gradually regressed after sequential intracystic injection of absolute ethanol and minocycline.
Conclusion:The rapid disappearance of the cyst was considered to be due to intraperitoneal rupture. The patient was asymptomatic just after rupture, but complained of back pain possibly because the regrowth was rapid. In some cases of huge hepatic cyst, rupture may be dismissed because it can be asymptomatic and the cystic fluid may have possibly already accumulated by the time symptoms appear.
