(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Koyun, N.; Akyol, V.; Elasan, S.; Göya, C.; Gizli, G.
SARS-CoV-2 (COVID-19), a previously unidentified type of coronavirus in humans, causes respiratory tract infection. The infection is transmitted by droplets and leads to several serious diseases characterized by acute respiratory distress syndrome (ARDS). We aimed to examine the changes in the volumes of lung regions infected with COVID-19, a new and highly pathogenic strain, according to age and gender. After obtaining ethical permission, 6700 patients who applied with positive COVID-19 test were selected between 01/03/2020 and 01/03/2021. Patients with asthma, bronchiectasis, obstructive pulmonary disease, pleurisy, allergic lung disease, lung tumor, and smokers were excluded from the study. After the excluded patients, computed tomography images of a total of 407 COVID-19-positive patients, 188 women, and 219 men, were obtained retrospectively. From the images taken, 2 to 10-decade groups of male and female patients between the ages of 10 and 100 were formed for the study. Images were skipped at certain intervals from the lung CT images for each patient in the groups. By applying stereological methods to the images, the total volume of the lung and the volumes of the infected lung regions were calculated. In the analysis of the infected COVID-19 lung volume/total lung volume (%) ratio by gender and decades, there was a statistically significant difference according to gender in the 2nd, 6th, and 9th decades [(p=0.002), (p=0.001) and (p=0.032)] was observed. In the comparison of the infected COVID-19 lung volume/total lung volume ratio by decades, a statistically significant difference was observed in both genders (p=0.001). Further studies and medical research are needed to better understand age-and sex-specific differences for effective intervention. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Computed Tomography Findings of Atypical Intralobar Pulmonary Sequestration: a Case Series
(Tabriz University of Medical Sciences, 2021) Özkaçmaz, S.; Özgökçe, M.; Akıncı, M.B.; Durmaz, F.; Dündar, İ.; Göya, C.; Sayır, F.
Introduction: Bronchopulmonary sequestration is a rare congenital abnormality of the lung that has two different types as intralobar and extralobar. In this study, we aimed to present six cases of intralobar sequestration with atypical findings in terms of feeding, drainage, and localization. Methods: Patients diagnosed with intralobar pulmonary sequestration in our clinic between 2015 and 2019 were evaluated retrospectively. Demographical features and atypical computed tomography (CT) findings of the patients were presented by literature. Results: Among 45 patients with intralobar sequestration, 6 (13.3%) (5 males and 1 female) with a mean age of 43.5±25.4(0-78) years old had atypical pulmonary findings on CT images. Atypical features regarding arterial supply was detected in 8.9%, venous drainage in 2.2%, location in 4.4%, radiological appearance in 4.4% and co-existing lesion in 2.2% of the patient with intralobar sequestration. Conclusion: Typical and atypical features of pulmonary sequestration must be well-known for differential diagnosis of solid or cystic pulmonary lesions. © 2021 The Author(s).
Quantitative Volumetric Assessment of Pulmonary Involvement in Patients With Systemic Sclerosis
(AME Publishing Company, 2016) Cetinçakmak, M.G.; Göya, C.; Hamidi, C.; Tekbas, G.; Abakay, Ö.; Batmaz, I.; Bilici, A.
Background: Computed tomography (CT) is the gold standard for assessing interstitial lung disease (ILD) in patients with systemic sclerosis (SSc). In this study, we performed a quantitative calculation of ILD severity by examining the lung volume of SSc patients. Methods: The present study was performed retrospectively on 38 patients with SSc who were referred to our clinic. Patients were divided into two groups based on high-resolution computed tomography (HRCT): patients with ILD and patients without ILD.The percentage of lower lobe volume (PLLV) was calculated using HRCT. In addition, we evaluated the PLLV in all patients according to age, diffusing capacity of the lung for carbon monoxide (DLCO) and spirometric findings, and assessed the relationships among these factors. Results: PLLV of the right lung in patients with ILD was reduced when compared with patients without ILD (P=0.041). The PLLV of the right lung in patients with ILD was negatively correlated with age and forced vital capacity (FVC; P=0.01 and P=0.012, respectively). Conclusions: The PLLV of the right lung may decrease in SSc patients with ILD. In these patients, the PLLV may be a quantitative parameter indicating damage in the lung.
Radiological Tips on Safe Tract Selection in Computed Tomography-Guided Transthoracic Biopsy: Single-Center Results
(Tabriz University of Medical Sciences, 2024) Koca, H.; Özgökçe, M.; Akinci, M.B.; Durmaz, F.; Ayyildiz, V.A.; Özkaçmaz, S.; Göya, C.
Introduction: The vast majority of lung masses are malignant. Benign lung masses include granulomatous inflammation and pneumonia consolidations. Malignant lung masses include lung cancers, lymphoma, and thymic neoplasms. Differentiating benign-malignant lung masses and treatment planning are essential for the prognosis of patients. Computed tomography (CT) guided transthoracic lung biopsy is a reliable diagnostic method with high accuracy and relatively few complications when an appropriate trace is selected. In this study, we aimed to present our experience and the results of lung mass cases that we biopsied with the guidance of CT. Methods: A total of 57 patients who were referred to us for clinicoradiological transthoracic biopsy (TTB) were studied with CT-guided histopathological sampling. The study did not include patients with no pathology results and ultrasound-guided biopsy. Results: A total of 57 patients, 42 male (73.6%) and 15 female (26.4%) with a mean age of 59.05 ± 17.04 (1-85), were evaluated. Thirteen of the lesions were reported as benign (22.8%), and 44 as malignant (77.2%). Conclusion: When an appropriate trace is selected, CT-guided transthoracic lung biopsy is a reliable diagnostic method with high accuracy and relatively few complications. © 2024 The Author(s).
Type and Fusion Identification by Age and Sex in Human Hyoid Bone Using 3d Ct Images in a Turkish Sample
(Yuzuncu Yil Universitesi Tip Fakultesi, 2024) Mutlu, G.D.; Aşırdizer, M.; Kartal, E.; Keskin, S.; Mutlu, İ.; Göya, C.
The morphometric measurement of the hyoid bone has been extensively studied in the literature, although morphological evaluations are covered in a limited number of studies. The aim of this study was to ascertain the fusion status and hyoid bone type and their relationships with age groups and sex. An examination was made of computed tomography scans of 320 patients. The types and degrees of fusion of the hyoid bone were determined. Hyoid type-U was most frequently observed in males (25.6%), type-D in females (31.9%) and the overall population (30.8%). There was no statistically significant difference in fusion formation on the right and left sides. The number of bones with fusion increased in both sexes with age (p=0.001). The earliest fusion observed was in a case aged 16 years, and 50% of the cases did not have fusion at age 61 years or older. Unlike previous studies, hyoid type and fusion status were evaluated using discriminant function analysis. Hyoid type and fusion cannot be indicative criteria for sex and age determination, but it might be feasible to accurately identify a person younger than twenty years old. The data obtained in the current study can be considered to make an important contribution to future studies. © 2024, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
Us and Ct Findings of Hibernoma in an Unusual Location
(2013) Yavuz, A.; Bora, A.; Beyazal, M.; Göya, C.
Hibernomas are asymptomatic, slow-growing tumors occurring in the anatomical sites where of brown fatty tissue was found in fetal life such as inter-scapular region or thigh. Retroperitoneal localization is an unusual site for this tumor and only few cases have been published in the literature. These tumors are benign in nature without any recurrence after total excision or evidence of metastasis. The purpose of this presentation is to demonstrate the US and CT findings of retroperitoneal hibernoma with the review of the literature.
