Congenital anomalies and genetic syndromes in 173 cases of medulloblastoma.

Abstract

One hundred seventy-three consecutive cases of medulloblastoma recorded in the Manchester Children's Tumour Registry from 1954 to 1989 were studied. After review of case notes, X-rays, and health surveys the clinical outcome and incidence of congenital anomaly was determined. A previously unreported association with Rubinstein Taybi syndrome was found. Evidence of a genetic syndrome or congenital anomaly was found in 6.4%. These figures provide further evidence of the higher-than-expected incidence of congenital abnormalities.
