Cortical Laminar Necrosis as a Result of Status Epilepticus After Resection of Parafalcal Meningioma.

We present a 45-year-old woman who was operated on for left frontal lesion with radiological features compatible with anterior falx meningioma. Postoperative clinical and electroencephalographic data were compatible with non-convulsive status epilepticus originating from the occipito-mesial area. MRI showed bilateral diffuse temporo-occipital abnormally bright cortex as a consequence of neuronal apoptosis compatible with laminar cortical necrosis, and clinical examination revealed persistent cortical blindness. The pathogenesis of encephalopathic syndromes is still unclear. Non-convulsive status epilepticus should be considered as a possible cause of late recovery of consciousness in neurosurgery patients. Delayed treatment may cause irreversible lesions, including in brain areas far from the surgical field. PMID: 32243562 [PubMed - as supplied by publisher]
