Subependymal Heterotopy: Gray Matter Heterotopia in a Patient Presenting with Non-convulsive Status Epilepticus

Subependimal Heterotopi: Non Konvülzif Status Epileptikus ile Gelen Hastada Gri Madde Heterotopisi

Abstract

Subependymal heterotopia is the most common subtype of gray matter heterotopies. It occurs as a result of a defect in neuronal migration. Subependymal heterotopia may cause epileptic seizures. A 51-year-old patient who was admitted to our clinic with unconsciousness was diagnosed as non-convulsive status epilepticus by clinical and electroencephalography findings. Subependymal heterotopy was also detected in the magnetic resonance imaging of the patient who recovered with antiepileptic treatments. This case is presented to draw attention to the non-convulsive status epilepticus, which is challenging to recognize and subependymal heterotopia, which may be encountered in the etiology of epileptic seizures.

Özet

Subepandimal heterotopi gri madde heterotopilerinin en sık görülen alt tipidir. Nöronal migrasyondaki defekt sonucu oluşur. Subepandimal heterotopi epileptik nöbetlere neden olabilir. Bilinç bozukluğu ile kliniğimize yatırılan 51 yaşındaki hastaya klinik ve elektroensefalografi bulgularıyla beraber non-konvulsif status epileptikus tanısı konuldu. Antiepileptik tedaviler ile kliniği düzelen hastada manyetik rezonans görüntülemede de subepandimal heterotopi saptandı. Tanınması oldukça zor olan non-konvulsif status epileptikusa ve epileptik nöbetlerin etyolojisinde karşılaşılabilen subepandimal heterotopiye dikkat çekmek için bu vaka sunulmuştur.
