    MRS features during encephalopathic crisis period in 11 years old case with GA-1
    (2015-05-01) Kurtcan, SERPİL; AKSU, Banu; Alkan, ALPAY; GULER, Serhat; Iscan, AKIN; KURTCAN, SERPİL; ALKAN, ALPAY; İŞCAN, AKIN
    Glutaric aciduria type-1 (GA-1) is a disorder of amino acid metabolism. The usual clinical-onset is an acute encephalopathic crisis in early childhood. There are only a few cases diagnosed in older age groups. MRI features of the disease are well defined. However, there are limited number of studies concerning advanced neuroimaging findings. We present DWI and MRS findings of an 11 year-old GA-1 patient admitted with an encephalopathic crisis. Diffusion restrictions in bilateral basal ganglia, corpus callosum and periventricular deep white matter were observed. In left occipital periventricular white matter and left basal ganglia, mild increased Cho/Cr and MI/Cr ratios and decreased NAA/Cr ratio were detected. Also inverted double lactate peak (TB: 135 ms) was present at 1.33 ppm in the left basal ganglia. In addition to these findings, a peak at 1.56 ppm above the baseline was seen on both short and long echo-time MRS in left occipital lobe deep white matter which may show accumulation of degradation products of amino acids in the GCDH enzyme deficiency.

    Diffusion tensor imaging findings of the brainstem in subjects with tonsillar ectopia
    (2018-03-01) Kurtcan, SERPİL; Alkan, ALPAY; YETIS, Huseyin; TÜZÜN, Umit; Aralasmak, AYŞE; Toprak, HÜSEYİN; Ozdemir, HÜSEYİN; KURTCAN, SERPİL; ALKAN, ALPAY; ARALAŞMAK, AYŞE; TOPRAK, HÜSEYİN; ÖZDEMİR, HÜSEYIN
    We aimed to evaluate the differences between apparent diffusion coefficient (ADC), fractional anisotropy (FA), axial diffusivity (AD), and radial diffusivity (RD) values obtained from different cranial sites in subjects with Chiari I Malformation (CM-I) and borderline tonsillar ectopia (BTE), and to determine correlations between diffusion tensor imaging (DTI) metrics and the severity of tonsillar ectopia. A total of 73 subjects with CM-I and BTE and 35 control underwent MRI and DTI. In our study, ADC values measured from the level of medulla oblongata and the RD values measured in middle cerebellar peduncles, thalamus, and globus pallidus were higher in CM-I patients than in controls. FA values at the medulla oblongata level and AD values at the medulla oblongata and pons level higher in patients with CM-I. ADC and AD values measured at the pons level were higher in BTE subjects than in controls. Compared with BTE, the CM-I subjects- ADC values at the medulla oblongata and AD values at the pons level were higher. In addition, FAs at the pons and medulla oblongata level were higher. At the medulla oblongata level, a positive correlation was observed between ADC and the size of tonsillar ectopia. AD and FA values measured at the level of medulla oblongata and pons were positively correlated with the size of tonsillar ectopia. These findings may be related to the severity of microstructural changes involving neuronal tracts at the brainstem level due to tonsillar ectopia. DTI may be useful in determining the extent of microstructural changes at the tissue level in subjects with tonsillar ectopia.

    Craniocervical Dissections: Radiologic Findings, Pitfalls, Mimicking Diseases: A Pictorial Review
    (2018-01-01) MEHDI, Elnur; Aralasmak, AYŞE; Toprak, HÜSEYİN; Yildiz, Seyma; Kurtcan, SERPİL; Kolukisa, MEHMET; Asil, TALİP; Alkan, ALPAY; ARALAŞMAK, AYŞE; TOPRAK, HÜSEYİN; YILDIZ, ŞEYMA; KURTCAN, SERPİL; KOLUKISA, MEHMET; ASİL, TALIP; ALKAN, ALPAY
    Background: Craniocervical Dissections (CCD) are a crucial emergency state causing 20% of strokes in patients under the age of 45. Although DSA (digital substraction angiography) is regarded as the gold standard, noninvasive methods of CT, CTA and MRI, MRA are widely used for diagnosis. Aim: Our aim is to illustrate noninvasive imaging findings in CCD. Conclusion: Emphasizing on diagnostic pitfalls, limitations and mimicking diseases.

    Relationship between the corpus callosum and neurocognitive disabilities in children with NF-1: diffusion tensor imaging features
    (2016-11-01) Aydin, SİNEM; Kurtcan, SERPİL; Alkan, ALPAY; GULER, Serhat; FILIZ, Mekiya; YILMAZ, TEMEL FATİH; SAHIN, Turkan Uygur; Aralasmak, AYŞE; AYDIN, SİNEM; KURTCAN, SERPİL; ALKAN, ALPAY; YILMAZ, TEMEL FATİH; ARALAŞMAK, AYŞE
    Purpose: Mild neurocognitive disabilities are commonly observed in children with neurofibromatosis type 1 (NF-1). Enlargement of the corpus callosum (CC) is one of the findings in NF-1, but the pathogenesis has not yet been clarified. In this study, we investigated whether diffusion tensor imaging (DTI) features of CC differed between children with NF-1 and healthy control subjects, and we tried to evahlate the association between the microstructural integrity of CC and neurocognitive disabilities, based on apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values.

    Susceptibility Weighted Imaging Features of Nonketotic Hyperglycemia: Unusual Cause of Hemichorea-Hemiballismus
    (2015-03-01) ATAY, Musa; YETIS, Huseyin; Kurtcan, SERPİL; Aralasmak, AYŞE; Alkan, ALPAY; KURTCAN, SERPİL; ARALAŞMAK, AYŞE; ALKAN, ALPAY
    Nonketotic hyperglycemia has been described as a metabolic cause of Hemiballism-hemichorea (HB-HC), especially in elderly patients with poorly controlled diabetes. Pathophysiology is not known yet. MRI features tend to be hyperintense in the putamen on T1-weighted images. We present conventional MRI with diffusion weighted imaging (DWI) and susceptibility weighted imaging (SWI) features of two cases with nonketotic hyperglycemia. T1 hyperintensity without diffusion restriction on DWI and minimal putaminal hypointensity without phase shift on SWI were compatible with either pathological mineralization or petechial microhemorrhage or protein denaturation. In the type 2 diabetic patients with HC-HB, conventional MRI together with SWI and DWI will guide to clinician to plan treatment approach.
