A previously healthy female, aged 4 years 3 months, developed brainstem encephalitis with clinical manifestations of fever, decreased level of consciousness, and left facial and abducens paralysis 1 week after bilateral parotitis. Twenty days after remission of encephalitis, she manifested new symptoms of ataxia, dysarthria, and fever. Magnetic resonance imaging revealed multiple hyperintense lesions which were increased in size when compared with the first magnetic resonance imaging. She was treated with glucocorticoids and intravenous immunoglobulin. Forty-eight days after therapy, she was able to walk with support and recovered completely on follow-up. Brainstem encephalitis and acute disseminating encephalomyelitis are discussed as rare complications of mumps.
Möbius syndrome is characterized by congenital facial diplegia, and may be associated with limb or orofacial malformations. A number of mechanisms have been proposed to explain the pathogenesis, including prenatal ischemia. We identified seven children with Möbius syndrome over the 10-year interval 1992-2001, all of whom manifested incomplete bilateral facial palsy. Associated limb and orofacial anomalies were observed in six cases. Computed tomographic scans were available in six children, and five of them manifested brainstem calcification which was most prominent in the floor of the fourth ventricle. The calcification was detected as early as 7 days of age and did not change with time, suggesting a static condition of prenatal onset. These observations support the hypothesis that the pathology in Möbius syndrome is secondary to prenatal brain ischemia.
We report a patient who presented progressive cerebellar ataxia associated with vitamin B(12) deficiency. Brain magnetic resonance imaging (MRI) demonstrated a diffuse leukoencephalopathy. Six months after the initiation of methylcobalamin therapy, there were clinical improvement and reduction in the MRI abnormalities.
