Abstract

Introduction

Simple cysts are the most common cystic abnormality encountered in the kidney and are caused by large family of hereditary, sporadic, developmental and acquired disorders. Most increase with age and appear to grow more rapidly in younger patients. Association with renal cell carcinoma and hypertension has been reported. Giant renal cyst measuring more than 15.0cm in diameter and containing more than 1500mls of serous fluid are rarely seen.

Case report

We report a case of giant right renal cyst in a 22- year old female of the Yoruba ethnic group in Western part of Nigeria. The cyst measured 60.0 x 42.0 x 25.0cm, with 20,600mls of serous fluid and weighing 12,145gm. She underwent radiological and other routine investigations and subsequently had laparotomy with total excision. Histology confirmed the diagnosis of simple multi-locular renal cyst. The patient had uneventful recovery period and subsequently discharged home after a week in the hospital.

Conclusions

Renal cyst can reach enormous size. This to the best of our knowledge is the largest renal cyst in the medical literature. Studies are needed with particular attention to the factors associated with and if possible the etiology of rapid renal cyst enlargement, the association with hypertension and renal cell carcinoma.

Key words
