Mumps Meningo-encephalitis

Abstract

Histological examination of brains of four children and one man dying with encephalitic symptoms within a few days of an attack of Asian influenza showed, in the children, scanty microglial infiltrations principally in the cerebellar cortex and also in the spinal cord; in the man, an acute haemorrhagic leuco-encephalitis. In one brain no abnormality other than congestion could be found. The remainder showed also slight lympho- cytic infiltration of the perivascular spaces and meninges.
