Radiological determination of fossa cranii posterior morphometry in Chiari malformation type I

Abstract

Purpose: The aim of this study is to evaluate the morphological changes in Magnetic Resonance Images (MRI) of Chiari Malformation Type-1 (CMI) patients by performing morphometric measurements of fossa cranii posterior (FCP) and cranium. Materials and Methods: Our study is retrospective and included a control group of 32 (16 females, 16 males) and 12 patients (6 males, 6 females) with CMI between the ages of 21 and 47 years. Measurements were made on T2-weighted cranial MR images of the patient with CMI and the control group. Results: Maximum cranial length, maximum cranial height, sagittal diameter of foramen magnum, cranium base length, supraocciput, clivus length, anterior-posterior diameter of fossa cranii posterior, occipital cord length, cerebellum height, amount of herniation in CMI were found 164.13±10.67mm, 134.60±10.71mm, 36.89±5.28mm, 108.5±7.9mm, 38.5±3.7 mm, 36.7±7.1mm, 84.9±8.8mm, 79.7±11.5mm, 53.3±4.2mm, 7.8±4.9mm respectively. Conclusion: In our study, the measurements of the CMI and the control group were compared and a decrease in the length of the supraocciput, the length of the clivus and the length of the occipital cord has been found and an increase in the length of the cranial base and the sagittal diameter of the foramen magnum has been found in CMI patients. As a result of the data obtained in our study, FCP morphometry of patients with CMI can contribute to patient follow-up and surgery.

Chiari malformasyonu Tip-I’de fossa cranii posterior morfometrisinin radyolojik olarak değerlendirilmesi

Öz

Amaç:. Bu çalışmada, Chiari Malformasyonu Tip-I hastaları ve kontrol grubuna ait Manyetik Rezonans (MR) görüntülerinde fossa cranii posterior (FCP) ve cranium’ a ait morfometrik ölçümler yapılarak oluşan morfolojik değişiklikleri değerlendirmek amaçlandı. Gereç ve Yöntem: Çalışmamız retrospektif nitelikte olup çalışmaya 21 ve 47 yaş aralığında 32 kişilik kontrol grubu (16 kadın, 16 erkek) ve 12 kişilik CMI’ lı hasta grubu (6 erkek, 6 kadın) dahil edildi. CMI’ lı hasta ve kontrol grubuna ait T2 ağırlıklı MR görüntüleri üzerinde ölçümler yapıldı. Bulgular: Maksimum cranial uzunluk, maksimum cranial yükseklik, foramen magnum sagittal çapı, basis cranii uzunluğu, supraocciput uzunluğu, clivus uzunluğu, fossa cranii posterior’ un ön-arka çapı, occipital cord uzunluğu, cerebellum yüksekliği, herniasyon miktarı CMI’ lı hastalarda sırasıyla 164.13±10.67mm, 134.60 ±10.71 mm, 36.89±5.28 mm, 108.5±7.9 mm, 38.5±3.7 mm, 36.7±7.1 mm, 84.9±8.8 mm, 79.7±11.5 mm, 53.3±4.2 mm, 7.8±4.9 mm olarak ölçüldü. Sonuç: Sağlıklı bireylere ait değerlerle karşılaştırıldığında, CMI’lı hastalarda foramen magnum ön-arka çapında ve tonsiller herniasyonda artış; clivus uzunluğu, occipital cord uzunluğu ve supraocciput uzunluğunda azalma olduğu görüldü. CMI‘lı hastalara ait FCP morfometrisinin bilinmesinin hastaların takibine ve cerrahisine katkı sağlayacağı düşünüldü.
