Cranioencephalic trauma is an event caused by force on the container that holds the brain content, which causes inertia to cause acceleration and deceleration injuries, producing hemorrhages and/or fractures; These can generate a series of complications such as epidural abscess which, being very close to the brain, constitutes an emergency for its management and follow-up15. On this occasion we show the case of a patient with epidural abscess caused by cranioencephalic trauma and neurosurgical management.

Primary brain lymphoma is a type of aggressive non-Hodgkin lymphoma that originates in the central nervous system and is diagnosed when there is no evidence of lymphoma anywhere else in the body. Although systemic lymphomas are better known and studied, primary brain lymphoma has been less understood due to its low frequency until a few decades ago. The treatment of this disease continues to be debated. On this occasion, the unusual case of large B cell lymphoma NOS associated with hydrocephalus and its management is reported.

El linfoma cerebral primario es una variedad de linfoma no Hodgkin agresivo que se origina en el sistema nervioso central y se diagnostica cuando no hay evidencia de linfoma en ninguna otra parte del cuerpo. Aunque los linfomas sistémicos son más conocidos y estudiados, el linfoma cerebral primario ha sido menos comprendido debido a su baja frecuencia hasta hace algunas décadas. El tratamiento de esta enfermedad sigue siendo objeto de debate. En esta oportunidad se reporta el inusual caso de linfoma B de células grandes NOS asociada a hidrocefalia y su manejo.
