    [Cerebral cystic echinococcosis in the light of our experience].; [Klinik deneyimlerimiz işiǧinda serebral kistik ekinokokkoz.]
    (2013) Duransoy Y.K.; Mete M.; Selçuki M.
    Cerebral cystic echinococcosis (CCE) is rare and constitutes 1-2% of all cystic echinococcosis. The cysts are usually solitary and most frequently located in the supratentorial region. CCE is classified as primary and secondary. The primary cysts developed from the embryos which escaped from the filter systems are more frequent and usually solitary and fertile. The secondary cysts result from spontaneous, traumatic or surgical rupture of the primary CCE by embolization of scolices. They are usually multiple and infertile and do not have brood capsule or scolices. Symptoms usually develop slowly and are usually due to increased intracranial pressure and depend on the location of the cyst. Diagnosis is made by evaluation of both clinical and laboratory findings. Computed tomography and magnetic resonance imaging is successful in the diagnosis. The cysts are observed as spherical, well defined, with thin regular margins by these methods. The most appropriate treatment method is total surgical removal of the cyst without rupture by using Dowling's method. However, when it is not possible to remove without rupture, the cyst should be removed totally after puncture and aspiration of contents of the cyst. After removal of large cysts, complications such as porencephalic cysts and subdural hemorrhage can occur postoperatively.

    Multislice computed tomographic measurements of optic nerve sheath diameter in brain injury patients; [Beyin hasarı olan hastalarda çok kesitli bilgisayarlı tomografide optik sinir kılıfı ölçümleri]
    (Turkish Association of Trauma and Emergency Surgery, 2018) Özsaraç M.; Düzgün F.; Gölcük Y.; Pabuşcu Y.; Bilge A.; İrik M.; Yılmaz H.
    BACKGROUND: Currently, the measurement of optic nerve sheath diameter (ONSD) has been offered as a possible indicator of intracranial pressure (ICP). Increased ICP is observed during intracranial injury. The objective of this study was to evaluate the relationship between increased ONSD and positive intracranial findings from multislice computed tomography (CT) of the brain. METHODS: In total, CT scans of 161 patients were retrospectively reviewed. The image that showed the largest ONSD was magnified five times. RESULTS: The CT scan revealed intracranial lesions in 54 patients and no intracranial lesions in 107 patients. A significant relationship was observed between positive CT findings and increased ONSD: 5.60±0.75 mm vs. 5.35±0.75 mm (p=0.038). The area under the receiver operating characteristic curve was 0.600 (95% confidence interval, 0.508–0.692; p<0.039). A cut-off value of ≥5.0 mm had a sensitivity and specificity of 80% and 36%, respectively. CONCLUSION: This study demonstrated a significant yet poor relationship between intracranial injury and increased ONSD from the multislice CT scan. Severe structural changes in the brain and trauma that causes bleeding have only limited effects on the extension of the optic nerve. © 2018 Turkish Association of Trauma and Emergency Surgery.
