RESUMO
Brain MRI was originally considered to appear normal in neuromyelitis optica spectrum disorders (NMO-SD). Typical brain lesions are now well described and have been integrated in the latest revision of NMO-SD criteria, but the NMO-SD MRI pattern remains not yet comprehensive. We report here extensive white matter lesions (EWML) mimicking leukodystrophy in a 50-year-old woman with long-lasting anti-AQP4+ NMO-SD. We suggest that EWML could be a possible brain MRI presentation of NMO-SD patients.

Background Paraganglioma is a rare neuroendocrine tumour arising anywhere along the paravertebral sympathetic and parasympathetic chains. In the neck, paraganglioma may affect the carotid body (carotid body tumour). Case report We describe a 43-year-old woman who presented with a reversible vasoconstriction syndrome associated with a posterior reversible encephalopathy syndrome following a surgery for a left carotid paraganglioma (with a past medical history of surgery for a right carotid paraganglioma a few months before). Conclusion A consequence of a baroreflex modification is discussed in order to explain the rare occurrence of such symptoms.
