Spectrum of Glomerulocystic Kidneys: A Case Report and Review of the Literature

An 8-year-old boy developed end-stage renal disease 7 years after the in utero diagnosis of bilateral cystic kidneys. There was no history of cystic renal disease in the family. Initial ultrasonographic screening of the parents failed to reveal cysts in the kidneys. Pathological evaluation of the kidney biopsy findings was consistent with the glomerulocystic kidney disease. He had bilateral nephrectomies in preparation for a living related renal transplant at 7 years of age. At that time, a repeated renal ultrasound examination of the mother showed bilateral cystic kidneys. Pathological evaluation of the nephrectomy specimens confirmed the diagnosis of autosomal dominant polycystic kidney disease. In this report, a discussion of the differential diagnosis of glomerular cysts and the relationship of glomerulocystic kidney disease and autosomal dominant polycystic kidney disease is provided.
