    Reliability of coeliac and superior mesenteric artery origin level in lumbosacral transitional vertebrae detection and vertebral numbering
    (2022-01-01) BALTACIOĞLU, FEYYAZ; BIYIKLI, ERHAN; Biyikli E., Sever I. H., BALTACIOĞLU F.
    the detection of lumbosacral transitional vertebrae (LSTV) and vertebral enumeration. Patients and Methods: Institutional review board approval was obtained. Routine lumbar magnetic resonance (MR) imaging that included sagittal cervicothoracic scout images in 972 cases were evaluated retrospectively. Six segments were created in the vertebral column with 7 lines. CA and SMA ostiums were localized in these segments. Results: Coeliac artery and SMA levels were detected more caudally in lumbarized S1 and more cranially in sacralized L5 cases compared to non-LSTV cases. Conclusion: Coeliac artery and SMA origin levels as anatomical markers are not dependable for vertebral numbering due to their wide variability

    Pilocytic Astrocytoma of the Cerebellopontine Angle with cerebrospinal fluid Spread in an Adult: A Case Report
    (2022-12-01) KURŞUN, MELTEM; OĞUZSOY, TUBA; BOZKURT, SÜHEYLA; BAYRAKLI, FATİH; BIYIKLI, ERHAN; Bıyıklı E., Kurşun M., Oğuzsoy T., Bozkurt S., Bayraklı F.
    Introduction Pilocytic astrocytoma of the cerebellopontine angle (CPA) is uncommon, and its spread to the cerebrospinal fluid (CSF) at the time of diagnosis has not been reported in the literature. Case Presentation We report the case of a 33-year-old man with multifocal pilocytic astrocytoma diagnosed by magnetic resonance imaging (MRI) and confirmed by histopathological examination, and present the radiological and histopathological findings. Conclusion In the case herein reported, we observed spread of the pilocytic astrocytoma of the CPA to the CSF at the initial diagnosis, and early detection by MRI is very important regarding the treatment modality and prognosis.

    Brain death in children: is computed tomography angiography reliable as an ancillary test?
    (2023-01-01) BIYIKLI, ERHAN; YAPICI, ÖZGE; ÖZTÜRK, MAKBULE NİLÜFER; Almus E., BIYIKLI E., YAPICI Ö., Almus F., Girgin F. I., Ozturk N.
    Background The diagnosis of brain death is primarily clinical. Sometimes ancillary tests are needed.

    Radiological and clinical features of multinodular and vacuolating neuronal tumor (MVNT)
    (2023-01-01) BIYIKLI, ERHAN; Bıyıklı E., Kursun M., Altuntas D., Bayri Y., Baltacioglu F.
    Background: To investigate the imaging fndings and clinical features of multinodular and vacuolating neuronal tumor (MVNT). Methods: We retrospectively sought for cases that have suspicious imaging fndings for MVNT through the hospital information system. The patients’ demographics and clinical symptoms were extracted. All available images were re-examined. Results: Headache was the most common complaint (n=7). Other complaints included seizure, stroke-like symptoms and numbness. Conventional MRI revealed that all lesions consisted of tiny, sharply marginated, round or ovoid nodules following the gyral contour. These nodules were hyperintense on T2 and FLAIR WI, hypointense on T1 WI. All lesions were characterized by a lack of enhancement and difusion restriction. Mass efect and peripheral edema were not observed. MVNT presented as an incidental fnding in one case who complained gynecomastia and had pituitary adenoma on pituitary MRI. All lesions were supratentorial—mostly on the right side (10/11)—and located in subcortical white matter. Follow-up MRI was available for 11 patients with a mean of 14.8 months (3–40 months). No change in lesion size and morphology was observed in these follow-up images. Conclusions: Radiological and clinical follow-up data suggest MVNT may exhibit indolent behavior. If asymptomatic, patients can be followed by imaging alone. Surgery should be considered for symptomatic patients.
