Giant simple renal cyst complicated with hypertension.

Solitary renal cysts are a common and usually asymptomatic occurrence in older patients. They may be associated with hypertension or abdominal disturbances, as they can be responsible for compression of surrounding tissues and distortion of renal vessels. This report presents an interesting case of a hypertensive patient with a solitary renal cyst of a marked size. Owing to the high risk of performing a surgical procedure in such a patient, a distinct therapeutic solution was opted for. Successful management of this case was achieved by a combination of percutaneous fluid aspiration and injection of alcohol and Vibramycin inside the cystic cavity. Percutaneous fluid evacuation combined with the administration of a sclerosing agent is suggested as a safe and effective alternative for cyst decompression and blood pressure normalisation.
