Abstract: | BACKGROUND Polycystic liver disease(PCLD) with a large cystic volume deteriorates the quality of life of patients through substantial effects on the adjacent organs,recurrent cyst infections, cyst rupture, and hemorrhage. Surgical or radiological intervention is usually needed to alleviate these symptoms. We report a rare case of the cystic metastasis of renal cell carcinoma(RCC), which was misdiagnosed as PCLD, as a result of the clinical and radiological similarity between these disorders.CASE SUMMARY A 74-year-old female who had undergone nephrectomy for papillary-type RCC(PRCC) was suffering from abdominal pain and the recurrent intracystic hemorrhage of multiple cysts in the liver. Imaging studies and aspiration cytology of the cysts showed no evidence of malignancy. With a diagnosis of autosomal dominant polycystic liver disease, the patient received hepatectomy for the purpose of mass reduction and infectious cyst removal. Surgery was performed without complications, and the patient was discharged on postoperative day 14. Postoperatively, the pathology revealed a diagnosis of recurrent PRCC with cystic formation.CONCLUSION This case demonstrates the importance of excluding the cystic metastasis of a cancer when liver cysts are observed. |
