Benign Multilocular Cyst of the Kidney

Definition

A benign multilocular cyst is a cystic kidney lesion in children (Cystic nephroma). Septa separate the cysts from each other.

Diagnosis

Ultrasound, intravenous urography, CT scan, or MRI of the abdomen. Neither test can differentiate between a benign multilocular cyst, multilocular cyst with partially differentiated Wilms tumor, or cystic Wilms tumor.

Treatment of the Benign Multilocular Cyst

Since imaging cannot differentiate between benign or malignant diseases, partial nephrectomy or nephrectomy is necessary, depending on tumor size (Okada, 2003).
