“…Furtado et al [4] found that the PCF volume in childhood patients with CMI was significantly lower than that in the control group (p = 0.002). They found that the mean PCF volume was 204.1 cm 3 in patients with CMI and 252.8 cm 3 in the age and sex matched control group.…”

“…In clinical and experimental studies, the cerebellar tonsillar herniation occurring in CMI is reported to mainly result from overcrowding of a normally developing hindbrain within a primary small and shallow PCF due to an anomaly in the embryological development of the occipital bone [1,3,4,7,9].…”

“…Posterior cranial fossa (PCF) abnormality of the skull is a developmental disorder and its variations have widely been reported in the literature [2,4,9]. Chiari malformations, Dandy Walker malformations, spina bifida and craniovertebral junction disorders are the common forms of the structural abnormality [1,7].…”

Amaç: Chiari malformasyonu tip 1 (CMT1), tonsilla serebelli'nin aşağıya, spinal kanala doğru herniyasyonu ile karakterize konjenital bir anomalidir. Bu çalışmanın amacı Chiari malformasyonu tip 1'li hastalarda ve kontrol grubunda ImageJ programı kullanarak 4. ventrikülün hacmini ve herniasyon gösteren tonsilla serebelli uzunluğunu belirlemektir. Gereç ve Yöntem: CMT1'li 27 hastanın manyetik rezonans (MR) görüntüleri retrospektif olarak incelendi (hasta grubu). Aynı zamanda baş ağrısı nedeniyle MR'ı çekilen, kranial ve intrakranial hiç bir patolojisi bulunmayan 18 kişi de kontrol grubu olarak incelendi. Hacim ve uzunluk değerleri ImageJ programı kullanılarak hesaplandı. Bulgular: 4. ventrikülün ortalama hacmi kontrol grubunda 1.08±0.20 cm 3 , hasta grubunda 1.01±0.27 cm 3 olarak belirlendi. İki gruptan elde edilen ventrikül hacimleri istatistiksel olarak farklı değildi (p>0.05). Hasta grubunda ortalama herniasyon uzunluğu 9.48±3.22 mm olarak bulundu. Her iki grupta da yaş ile diğer değişkenler (hacim ve uzunluk) arasında herhangi bir ilişki belirlenmedi (p>0.05). Sonuç: Bu çalışma 4. ventrikül hacminin ve herniasyon gösteren tonsilla serebelli uzunluğunun Image J programı ile ölçülebileceğini göstermiştir. Klinik bulgular ile korele edildiğinde bu ölçümlerin CMT1'li vakaların değerlendirmesine katkıda bulunacağını düşünmekteyiz.

Calculation of the Volume of Fourth Ventricle and the Length of Herniation Using the ImageJ Software in Patients with Chiari Type I malformationObjective: The Chiari type 1 malformation is a congenital anomaly which is characterized by downward displacement of the cerebellar tonsils into the cervical spinal canal. The aim of this study was to determine the volume of fourth ventricle and the length of herniated cerebellar tonsils in patients with Chiari type I malformation and control group using ImageJ program. Material and Methods: We retrospectively investigated magnetic resonance (MR) images from 27 patients with Chiari type I malformation (patient group). We also investigated MR images from 18 subjects as a control group who underwent an MRI complaining of headaches with the results showing no cranial or intracranial pathology. The volume and length were estimated using the ImageJ program Results: The mean volumes of fourth ventricle were determined as a 1.08±0.20 cm 3 and 1.01±0.27 cm 3 for control group and patient group, respectively. Ventricle volumes obtained from two groups were not statistically different (p>0.05). We found that the mean length of herniation was 9.48±3.22 mm in the patient group. We did not determine any relationship between age and any of these variables (volume and length) in both groups. Conclusion: This study has shown that the volume of fourth ventricle and the length of herniated cerebellar tonsils can be measured by ImageJ program. We think that when correlated with clinical findings, these measurements may contribute to the evaluation of Chiari type I malfo...

“…A wide spectrum of central nervous system (CNS) diseases in children have been associated with alterations in the size of the PCF or its contents. Several studies have compared PCF dimensions in patients with these conditions with those in control individuals (Kollias et al, 1993;Trigylidas et al 2008;Furtado et al, 2009). Although normative data could indirectly be derived from the control groups of these studies, few studies establish normative values for PCF dimensions (Habibi et al, 2011;Chadha et al, 2015).…”

ERTEKIN, T.; DEGERMENCI, M.; UCAR, I.; SAGIROGLU, A.; ATAY, E. & SUSAR, H.The intracranial and posterior cranial fossa volumes and volume fractions in children: A stereological study. Int. J. Morphol., 35(4):1465Morphol., 35(4): -1472Morphol., 35(4): , 2017. SUMMARY:The size of intracranial cavity (IC) and posterior cranial fossa (PCF) plays an important role in the pathophysiology of various disorders. In this study, we aimed at establishing normal volume data of the IC and PCF in Turkish population according to age and sex by using stereological method. This study was carried out retrospectively on 339 individuals (168 females and 171 males) between 0 and 18 years old with no medical or neurological disorders that affected the skeletal morphology of the cranial cavity. Volumetric estimations were determined on computed tomography (CT) images using point-counting approach of stereological methods. Intracranial volume (ICV) and posterior cranial fossa volume (PCFV) were increased with age in both sexes. They reached adult dimensions at 5 years of age during the teenage years. According to sex; the mean ICV and PCFV were 1594.51±245.57cm 3 and 244.89±53.86 cm 3 in males, 1456.34±241.85 cm 3 and 228.24±41.38 cm 3 in females, respectively. Generally, significant differences were determined in ICV and PCFV according to sex after they reached maximum growth period. According to age the volume ratios of PCF to IC was ranged from 13.03 to 17.48 in males and 12.06 to 18.54 in females. This study demonstrated that these volume ratios could help the physician for both patient selections for surgery, and for the assessment of any surgical technique used to treatment of PCF malformations. However current study revealed that point counting method can produce accurate volume estimations and is effective in determining volume estimation of IC and PCF.
