Central pontine myelinolysis (CPM) is an uncommon neurological syndrome that is usually related to the rapid restoration of a previous hyponatraemia. Although the most frequent location of CPM injury is the pons, it is now designated osmotic demyelination syndrome (ODS) because, as well as in the brainstem, these injuries can be observed in other parts of the central nervous system (CNS)-for example, the thalamus, subthalamic nucleus, external geniculate body, putamen, globus pallidum, internal capsule, white matter of cerebellum and the deep layers of the brain cortex. However, an exhaustive search of the literature (MEDLINE 1967-2007) has revealed no case report of peripheral nervous system (PNS) demyelination secondary to severe hyponatraemia.
RESUMO
El osteoma es una neoplasia benigna poco común, que se caracteriza por presentar un crecimiento óseo progresivo, el cual está compuesto por la proliferación bien diferenciada de hueso compacto y/o esponjoso. En el área maxilofacial se presenta con mayor frecuencia en la cara lingual posterior de la mandíbula. Se caracteriza por crecimiento lento y asintomático. El caso describe una paciente de 45 ños con un osteoma gigante mandibular de 4 años de evolución tratado quirúrgicamente.
Osteomas are considered a rare benign neoplasm, characterized by a progressive bone growth, which is composed of a proliferation well differentiated of compact or cancellous bone. In the maxillofacial area when present, commonly found in the posterior lingual surface of the mandible. It is characterized by slow growth and asymptomatic. The case describes a mandibular giant osteoma of 4 year of evolution treated with surgical treatment.
