Acquired glomerulocystic kidney disease following haemolytic-uraemic syndrome

Glomerulocystic kidney disease is a rare condition, usually seen in infants and young children, characterised by cystic dilatation of the glomeruli. It may be sporadic or represent the congenital expression of dominant polycystic kidney disease. Glomerular cysts may also be seen in association with various syndromes and as a component of dysplastic kidneys. Only two cases of acquired glomerulocystic kidneys have been described, both in adults. The cystic change followed haemolytic-uraemic syndrome in one patient and systemic sclerosis in the other. These two conditions are closely related and may be indistinguishable pathologically. We report a case of acquired glomerulocystic kidney in a child which followed the haemolytic-uraemic syndrome. The factors leading to glomerulocystic kidney following haemolytic-uraemic syndrome are unknown and need further evaluation.
