Aparece en muchas regiones del cuerpo y se presenta como una masa blanda, indolora y desplazable.  Información del paciente:  se presenta un paciente con un quiste dermoide localizado en el filum terminal que se muestra como una parálisis bilateral de ambos nervios ciáticos poplíteos externos y un nivel sensitivo dorsal D12. Se le realizó una resonancia magnética nuclear de columna dorso-lumbar que mostró la presencia de un tumor extramedular intradural y fue intervenido quirúrgicamente.  Conclusiones:  es importante una evaluación clínica amplia para poder llegar al diagnóstico positivo de estas formas atípicas de presentación de lesiones medulares con afectación de nervios periféricos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT  Introduction:  dermoid cysts are benign lesions that originate from ectodermal tissue that remains in the thickness of tissues during embryonic development of multipotential cells or perhaps epithelial implantation. Dermoid cysts appears in many regions of the body and is presented as a soft, painless and scrollable mass. Most are small, but some have exceeded 12cm. It often distend the mucosa in such a way that some of the contents may be visible. Dermoid cysts can be seen between 15 and 35 years of age.  Case report:  a clinical case of a dermoid cyst located in the filum terminal is presented, which presents as a bilateral paralysis of both external popliteal sciatic nerves and a dorsal sensory level D12, a nuclear magnetic resonance of the dorso-lumbar spine is performed and the presence of an intradural extramedullary tumor, which is surgically intervened.  Conclusions:  it is concluded histologically as a dermoid cyst.]]></p></abstract>
