Congenital unilateral cystic kidney

Unilateral localized cystic kidney: Answer

“…The lack of suspect lymph nodes and homogeneous tumor mass as well as the presence of cysts in other areas of the affected kidney in our patient made the diagnosis of cystic nephroma less likely. Unilateral renal cystic disease is a less well known entity reported that is non-familial and non-progressive [1,2]. Segmental multicystic dysplastic kidney disease was unlikely in our patient since on the CT scan there was normal contrast enhancement in the renal tissue adjacent to the cysts and a lack of evidence of duplication of the collecting system.…”

Massive unilateral hydronephrosis in early infancy

“…Cystic renal swellings may be due to congenital unilateral multicystic kidney disease : there are at least 46 recorded cases (Moe and Crofford, 1960). These may present in the neonatal period and early operation may be carried out, as in the infant recorded by Fillis, Grantham, and Cullen (1958) which was operated on when 15 days old. In such instances the outline of the mass is sometimes irregular on palpation, whereas in cases due to hydronephrosis the outline is smooth.…”

Ectopic Unilateral Multicystic Kidney in Infant

“…[2][3][4][5][6][7][8][9][10][11][12] This relatively small number perhaps is not indicative of the actual frequency of the disorder as adduced from the observations of Longino and Martin.13 To ascertain the nature and frequency of abdominal masses found on the first day of life these workers reviewed the admissions to the Children's Hospital of Boston for a 20-year period and found 32 infants to have an abdominal mass. In 1955 Spence2 reviewed 15 cases of this abnormality and added 4 of his own.…”
