Sekiz ardışık segmenti kapsayan çok nadir bir servikotorakal vertebral sinostoz olgusu: konjenital mi, edinsel mi?

Yaşlı bir kadın hasta travma sonrası akut boyun ağrısı ile başvurdu.Servikal direkt grafisinde 8 ardışık spinal seviyeyi kapsayanuzun segment servikotorakal vertebral füzyon saptandı. Hastaspinal bilgisayarlı tomografi (BT) ve magnetik rezonans (MR)görüntüleme, elektromiyografi (EMG), ve büyüme-farklılaşmafaktörü 6 [Growth differentiation factor 6 (GDF6)] gen mutasyonuanalizi ile detaylı tetkik edildi. Görüntüleme bulguları konjenitalblok vertebra için atipik olan olguda GDF6 gen mutasyonusaptanmadı. Hastanın eski tıbbi raporları ve anamnezinde adolesandönemde kronik ve kısmen tedavi edilmiş brucella spondilodiskitirehabilitasyonu amacıyla sanatoryumda uzun dönemli yatışmevcut idi. Birkaç seviyeyi kapsayan blok vertebra olguları dahaönceden bildirilmiş olmakla birlikte; bu, 8 ardışık vertebral cismikapsayan ilk edinsel servikotorakal füzyon olgusudur.

A very rare case of cervicothoracic vertebral synostosis spanning eight adjacent segments: congenital vs acquired

Cervical roentgenogram revealed a long-segment cervicothoracicvertebral fusion spanning 8 adjacent spinal levels. The patient wasevaluated with computed tomography (CT) and magnetic resonance(MR) imagings of the spine, electromyography (EMG) and growthdifferentiation factor 6 (GDF6) gene mutation analysis. Imagingfindings were atypical for congenital block vertebrae and therewas no GDF6 mutation. A revision of very old medical records andpatient’s recollections revealed long-term stay in sanatorium forrehabilitation of chronic partially-treated brucella spondylodiscitisduring adolescence. Block vertebrae spanning several levels havepreviously been reported; but, this is the first report of an acquiredcervicothoracic fusion spanning 8 adjacent vertebral bodies.
