Since these tumors grow linearly rather than exponentially, they grow gradually and thus do not cause mass effects and hydrocephalus. This study is the case report of a rare great volume left intraventricular epidermoid cyst rupture. The tumor was found to be associated with mass effect on neighboring structures and hydrocephalus.Publication Metadata only BRAIN TUMOR TREATMENT AND NANOTECNOLOGY(2017-11-08) DÜNDAR, TOLGA TURAN; SEYİTHANOĞLU, MEHMET HAKAN; GUNDAG, MELİHA; gökoğlu, abdulkerim; KİTİŞ, SERKAN; Özek, ERDİNÇ; Abdallah, Anas; Doğan, İhsan; Mutluer, Ahmet Serdar; DÜNDAR, TOLGA TURAN; SEYİTHANOĞLU, MEHMET HAKAN; GUNDAG, MELİHA; KİTİŞ, SERKANPublication Metadata only COMPARISON BETWEEN THE PRE- AND POSTOPERATIVE RADIOLOGICAL FINDINGS AND CLINICAL OUTCOMES EVALUATION OF THE PATIENTS WHO UNDERWENT SURGERY FOR LUMBAR SPONDYLOLISTHESIS(2018-04-01T00:00:00Z) Papaker, Meliha Gundağ; EMEL, ERHAN; Abdallah, Anas; SEYİTHANOĞLU, MEHMET HAKAN; DÜNDAR, TOLGA TURAN; Kitiş, Serkan; SEYİTHANOĞLU, MEHMET HAKAN; DÜNDAR, TOLGA TURANPublication Metadata only Yüksek gradlı glial tümörlerde yerleşim yeri,yaş ve cinsiyet dağılımları: son iki yıla ait Bezmialem sonuçları(2018-04-24T00:00:00Z) DÜNDAR, TOLGA TURAN; CAN, ENGİN; TEKİN, ABDURRAHİM; YAPAR, SELÇUK; GÖNEN, GÜVEN; Abdallah, Anas; Kitiş, Serkan; Ozek, Erdinc; Papaker, Meliha Gundağ; SEYİTHANOĞLU, MEHMET HAKAN; HATİBOĞLU, MUSTAFA AZİZ; DÜNDAR, TOLGA TURAN; CAN, ENGİN; YAPAR, SELÇUK; GÖNEN, GÜVEN; SEYİTHANOĞLU, MEHMET HAKAN; HATİBOĞLU, MUSTAFA AZİZPublication Metadata only Beyin Tümörü Kök Hücresi(2018-09-01T00:00:00Z) DÜNDAR, TOLGA TURAN; Kitiş, Serkan; Papaker, Meliha Gundağ; Abdallah, Anas; Ozek, Erdinc; SEYİTHANOĞLU, MEHMET HAKAN; ÇETİN, GÜVEN; DÜNDAR, TOLGA TURAN; SEYİTHANOĞLU, MEHMET HAKAN; ÇETİN, GÜVENPublication Metadata only Comparison of TOF MRA, Contrast-Enhanced MRA and Subtracted CTA from CTP inResidue Evaluation of Treated Intracranial Aneurysms(2017-11-10T00:00:00Z) DÜNDAR, TOLGA TURAN; SEYİTHANOĞLU, MEHMET HAKAN; ARALAŞMAK, AYŞE; Toprak, Huseyin; Kitiş, Serkan; Ozek, Erdinc; UYSAL, ÖMER; ALKAN, ALPAY; DÜNDAR, TOLGA TURAN; SEYİTHANOĞLU, MEHMET HAKAN; ARALAŞMAK, AYŞE; UYSAL, ÖMER; ALKAN, ALPAYPublication Open Access Investigation of Brain Impairment Using Diffusion-Weighted and Diffusion Tensor Magnetic Resonance Imaging in Experienced Healthy Divers.(2018-11-17) SEYITHANOĞLU, MEHMET HAKAN; ABDALLAH, ANAS ABDELRAHIM SA; Dündar, TOLGA TURAN; KITIŞ, SERKAN; ARALAŞMAK, AYŞE; Gündağ, Papaker; SASANI, H; SEYİTHANOĞLU, MEHMET HAKAN; ABDALLAH, ANAS ABDELRAHıM SA; DÜNDAR, TOLGA TURAN; KİTİŞ, SERKAN; ARALAŞMAK, AYŞE; GUNDAG, MELİHABackground: The aim of this study was to understand the changes of decompression illness in healthy divers by comparing diffusion-weighted (DWI) and diffusion tensor MRI findings among healthy professional divers and healthy non-divers with no history of diving. Material/Methods: A total of 26 people were recruited in this prospective study: 11 experienced divers with no history of neurological decompression disease (cohort) and 15 healthy non-divers (control). In all study subjects, we evaluated apparent diffusion coefficient (ADC) and type of diffusion tensor metric fractional anisotropy (FA) values of different brain locations (e.g., frontal and parieto-occipital white matter, hippocampus, globus pallidus, putamen, internal capsule, thalamus, cerebral peduncle, pons, cerebellum, and corpus callosum). Results: ADC values of hippocampus were high in divers but low in the control group; FA values of globus pallidus and putamen were lower in divers compared to the control group. DWI depicted possible changes due to hypoxia in different regions of the brain. Statistically significant differences in ADC values were found in hypoxia, particularly in the hippocampus (p=0.0002), while FA values in the globus pallidus and putamen were statistically significant (p=0.015 and p=0.031, respectively). We detected forgetfulness in 6 divers and deterioration in fine-motor skills in 2 divers (p=0.002 and p=0.17, respectively). All of them were examined using neuro-psychometric tests. Conclusions: Repeated hyperbaric exposure increases the risk of white matter damage in experienced healthy divers without neurological decompression illness. The hippocampus, globus pallidus, and putamen are the brain areas responsible for memory, learning, navigation, and fine-motor skills and are sensitive to repeated hyperbaric exposure
