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.
INTRODUCTION: Brainstem gliomas have historically been one of the most difficult pediatric cancers to treat. Tumors arising in the brainstem were once uniformly discounted as surgically unresectable lesions. Early neurosurgeons thought this location to be inoperable and fraught with disaster. The advent of computed tomography (CT), magnetic resonance imaging (MRI), and sophisticated neurophysiological monitoring techniques have significantly advanced the surgical treatment of these precarious lesions. REVIEW: Brainstem gliomas are now recognized as a heterogenous group of tumors. They have been broadly classified into several categories depending upon the classification scheme. All these classification systems provide a framework to predict growth patterns, surgical resectability, and overall prognosis of these tumors. These systems allow the surgeon to obtain a better understanding of the distinction between low-grade tumors and diffuse inoperable tumor types. The authors review the current literature and management of brainstem tumors.
