Is It Always Wilms’ Tumor? Localized Cystic Disease of The Kidney in An Infant: An Extremely Rare Case Report And Review of The Literature

Abstract

Localized Cystic Disease of the Kidney (LCDK) is an extremely rare benign disease in pediatric population. Although its management is conservative and generally requires no treatment, the unfamiliarity with the disease can expose such patients to misdiagnosis as renal malignancies or uncertainty for proper treatment. We report such a case in an infant and review the current literature.

Localized Cystic Disease of the Kidney in Pediatric Patients: Clinical and Imaging Findings With Long Term Follow Up

“…This is the rst study to report multiple cases of pediatric LCDK with long-term US follow-up. Lack of awareness of the disease may lead to misdiagnosis and mistreatment, including unnecessary nephrectomy, as in previously reported pediatric cases [5][6][7][8][9][10][11][12][13]. Of the 11 pediatric reported cases, seven cases underwent surgical excision [5,6,8,10,12,13,15].…”

“…Since then, many studies have documented this unique disease, mostly in the adult population. Only 11 pediatric cases have been documented thus far (Supplementary Table 1) [5][6][7][8][9][10][11][12][13]. Seven patients were male and four patients were female, with their age ranging from 1.5 months to 16 years.…”

“…Of the 11 pediatric reported cases, seven cases underwent surgical excision [5,6,8,10,12,13,15]. Among these seven cases, one patient underwent preoperative chemotherapy before nephrectomy because the radiologist suspected a malignant lesion [13]. Four cases were managed conservatively, and follow-up data were available in two cases.…”

“…There have been only 11 previously reported pediatric LCDK cases [5][6][7][8][9][10][11][12][13]. Since LCDK in the pediatric population is rare, more than 50% of these reported cases were misdiagnosed and underwent unnecessary surgical excision.…”
