Membranoproliferative glomerulonephritis was observed in a 22-year-old
male patient in whom a ventriculoatrial shunt and a ventricular cathe
ter were implanted after he was diagnosed in September 1989 with a cer
ebral cyst. Propionibacterium acnes infection of a central nervous sys
tem shunt was diagnosed. The venticuloatrial shunt was removed (the ca
theter had become embedded in tissue and was left in place) and the pa
tient was treated with cefotaxime (3 x 2 g) for 14 days. Renal functio
n improved, but recovery was not complete.
