    Investigating the Frequency of Stroke in SARS-CoV-2 Cases in Sakarya City, Turkey
    (2020) Kotan, Dilcan; Ateş, Ömer Faruk; Taydas, Onur; Öztürk, Mehmet
    Aim: The aim of this study is to identify the frequency of stroke among severe acute respiratorysyndrome coronavirus 2 (SARS-CoV-2) cases in Sakarya city, to find out the clinicalcharacteristics of patients diagnosed with stroke and to contribute to the national database.Material and Methods: This retrospective study was carried out with 783 cases diagnosedwith SARS-CoV-2 between April-June 2020 at the pandemic hospital in Sakarya city. Patientswere compared in terms of age, National Institute of Health Stroke Scale (NIHSS), risk factors,radiological findings, inpatient treatment, intubation, and mortality rates.Results: Out of 26 cases of ischemic stroke, 11 (42.3%) were male and 15 (57.7%) werefemale. In terms of infarction localization, the cause was medial cerebral artery (MCA) in 4(15.4%) patients, top of the basilar in 2 (7.7%) patients, basilar artery in 1 (3.8%) patient,lacunar in 9 (34.6%) patients and anterior system in 10 (38.5%) patients. There was nosignificant difference in terms of D-dimer and C-reactive protein (CRP) levels according todisease severity (both p=0.262). Three (0.38%) patients presented with stroke findings andwere diagnosed with SARS-CoV-2. Cryptogenic stroke was detected in 8 (30.8%) of theSARS-CoV-2 cases. Stroke frequency was calculated as 3.3% among the SARS-CoV-2 casesin Sakarya city.Conclusion: This is the first study to identify the frequency of stroke among SARS-CoV-2patients in Sakarya city and Turkey. Our study is important as it shows that preventing ortreating ischemic stroke in SARS-CoV-2 cases contributes greatly to the reduction ofmortality.

    Posterior shoulder labrocapsular structures in all aspects; 3D volumetric MR arthrography study
    (British Inst Radiology, 2021) Ogul, Hayri; Taydas, Onur; Sakci, Zakir; Altinsoy, Hasan Baki; Kantarci, Mecit
    Pathologies of the posterior labrocapsular structures of the shoulder joint are far less common than anterior labrocapsuloligamentous lesions. Most of these pathologies have been associated with traumatic posterior dislocation. A smaller portion of the lesions include posterior extension of superior labral anteroposterior lesions, posterior superior internal impingement, and damage to the posterior band of the inferior glenohumeral ligament. Labrocapsular anatomic variations of the posterior shoulder joint can mimic labral pathology on conventional MR and occasionally on MR arthrographic images. Knowledge of this variant anatomy is key to interpreting MR images and studying MR arthrography of the posterior labrocapsular structure to avoid misdiagnosis and unnecessary surgical procedures. In this article, we review normal and variant anatomy of the posterior labrocapsular structure of the shoulder joint based on MR arthrography and discuss how to discriminate normal anatomic variants from labrocapsular damage.

    Solitary Metastasis Mimicking Glioblastoma in a Patient with Fahr's Disease
    (Springer India, 2025) Taydas, Onur; Has, Busra; Sakci, Zakir; Ogul, Hayri; Kantarci, Mecit
    Fahr's disease is defined as the accumulation of bilateral idiopathic calcification in the basal ganglia, dentate nucleus, and centrum semiovale. The coexistence of Fahr's disease and intracranial tumors is extremely rare, with only five cases documented in the literature. This study aimed to present a rare case, discussing both similarities and differences with previously reported cases. A 70-year-old female patient presented to our hospital with a progressive headache over the past month. Brain magnetic resonance imaging (MRI) with intravenous contrast was performed for further evaluation. Bilateral basal ganglia, thalamus, and dentate nuclei showed calcifications consistent with Fahr's disease. After excluding toxic, infectious, and endocrine causes of calcification, the patient was diagnosed with Fahr's disease. Magnetic resonance imaging also revealed a midline localized, irregularly contoured, and heterogeneously intense mass with contrast enhancement at the centrum semiovale level, accompanied by peripheral edema. Radiologically, the mass resembled a high-grade glioma or metastasis, and the presence of a lipid peak further suggested metastasis. Based on radiological findings, the patient was diagnosed with brain metastasis of breast carcinoma. The patient received chemotherapy for metastasis, which resulted in substantial regression of the mass. In patients with known Fahr's disease, new-onset headaches and related symptoms should warrant evaluation for possible brain tumors. In these cases, imaging findings should be assessed along with physical examination findings and the patient's medical history to support the diagnostic process.
