LOPEZ L, Ingeborg; GONZALEZ L, Daniela; QUEZADA R, Patricio  e  CARTIER R, Luis. Continous partial status cause of hyperintensity in cerebral cortex in magnetic resonance imaging. Rev. chil. neuro-psiquiatr. [online]. 2012, vol.50, n.2, pp. 112-116. ISSN 0717-9227.  http://dx.doi.org/10.4067/S0717-92272012000200005.

Magnetic Resonance Imaging has demonstrated functional changes of the cerebral cortex in relation to status epilepticus, which can eventually localize the origin of the crisis. The purpose of this presentation is relevant to this condition and pretends to highlight the action of incidental situations that can modify it. We present a 29 year old woman with a neurosurgical intervention for a neuroblastoma irradiated fifteen years ago, which incidentally starts a continuous partial status epilepticus, expressed by clonies of the face and left limbs associated with functional impotence, resistant to oral therapy. Faced with the suspicion of recurrence of the tumor, a brain MRI is performed, showing hyperintensity of all neural areas the right hemisphere, with no evidence of tumor recurrence. Once submitted the status epilepticus, the hyperintensity disappeared in the hemisphere. This extensive reaction of the neural structures might be related to a permanent effect of radiation, which may have caused a mismatch functional glia, of the blood-brain barrier and interneural network.
