[Curable ECHO 5 virus encephalitis. Clinical, electroencephalographic, virologic and ultrastructural study].
A 10 1/2 years old boy fell brutally ill with a fit followed by confusion, and then by deep coma, with 40 degrees C fever and morbilliform rash. Consciousnesse came back within ten days, with transient Parkinson-like tremor. Myoclonus persisted for about six months. Complete recovery was followed up for six years. A diagnosis of encephalitis was considered on early EEG evidence (stereotyped repetitive sharp wave bursts) and was confirmed by isolation of ECHO 5 virus from brain specimen, and ultrastructural observation of characteristic cytopathic effect (disappearance of organelles, proliferation of smooth membranes) and of probable viral particules in astrocytes, without any inflammatory process.
