Brucellosis in the Head and Neck: a Forgotten Differential Diagnosis
(Yuzuncu Yil Universitesi Tip Fakultesi, 2024) Çetin, Y.S.; Dündar, İ.
Introduction: Patients with brucellosis present with nonspecific symptoms originating from different organs. In this study, we aimed to investigate the symptoms related to the head and neck region in patients with brucellosis. Materials and Methods: The retrospective study analyzed 542 patients with a definitive diagnosis of brucellosis who were admitted to our hospital between January 2015 and April 2022 and received outpatient and/or inpatient care. Clinical symptoms localized t o the ear-nose-throat and head and neck regions were evaluated. Results: A neck mass was detected in 52 out of 542 patients included in the study. The prevalence of cervical lymphadenopathy and/or abscess was 9.6%. Only lymphadenopathy was present in 30 (57. 7%) patients, while bo th neck abscess and lymphadenopathy were detected in 22 (42. 3%) patients. No significant difference was found between the two groups with regard to treatment regimens . Mean duration of treatment was 30 ± 22.1 (range, 14-70) days in the lymphadenopathy group and was 22 ± 14.7 (range, 14-60) days in the abscess group. No significant difference was found between the two groups with regard to the length of time to clinical recov ery. Conclusion: Brucellosis affects many regions of the head and neck and c an have a variety of imaging manifestations that mimic benign and malignant lesions. The diagnosis of brucellosis should be considered in the first-line differential diagnosis conducted based on imaging features in patients residing in endemic regions. © 2024, Yuzuncu Yil Universitesi Tip Fakultesi.

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).
Computed Tomography Findings of Isolated Peripheral Pulmonary Artery Aneurysms
(Tabriz University of Medical Sciences, 2021) Dündar, İ.; Türko, E.
Introduction: In this study, we aimed to evaluate computed tomography (CT) findings of peripheral pulmonary artery aneurysms (PPAA) associated with Behcet’s disease (BD), Hughes Stovin syndrome (HSS), and idiopathic origin. Methods: Contrast-enhanced CT scans of the patients were retrospectively reviewed regarding PPAA. The patients with PPAA were classified into BD, HSS, and idiopathic groups according to the etiology. The groups were compared for demographical features including age and gender, multiplicity, distribution of thrombosis and accompanying pulmonary artery embolism (PAE), and deep venous thrombosis (DVT) history. Results: A total of 30 PPAA (25.4 ± 13.4 [11-62] mm) were detected in 10 (2.3%) (mean age 39.8 ± 22-1.0 [8-73] years, female/male:3/7) among 4391 patients reviewed. In 7 patients, multiple aneurysms were detected, while a solitary lesion was seen in 3 patients. Most commonly, lower lobes (right 8-left 8, 53.2%) involvement was observed. A thrombosis was detected within 19 (63.4%) aneurysms. Among 10 patients with PPAA, 4 subjects (40%) had BD, 2 (20%) HS and 4 (40%) idiopathic origin. In 5 patients (50%), there was accompanying PAE and 3 patients had (30%) DVT history. Patients with BD and HSS tended to have multiple lesions than those with idiopathic origin. Accompanying PAE was observed in 2 (100%) of patients with HSS, 2 (50%) with BD, and 1 (25%) patient in the idiopathic group. A DVT history was recorded in 2 (100%) patients with HSS, 1 (25%) with BD. None of the patients in the idiopathic group had a DVT history. The only rupture was observed in the HSS group. Conclusion: Vasculitic diseases lead to PPAA, including BD and HSS which are more likely to be associated with complications and additional morbid conditions than idiopathic processes. © 2021 The Author(s).
Contrast Enhanced Computed Tomography Findings of Persistent Truncus Arteriosus; a Rare Congenital Heart Disease
(Elsevier Inc, 2020) Turkoglu, S.; Batur, A.; Yokuş, A.; Dündar, İ.; Akinci, M.B.
Persistent Truncus Arteriosus is a cyanotic congenital heart anomaly in which a single trunk supplies both the pulmonary and systemic circulation, instead of a separate aorta and a pulmonary trunk. It is usually classified as a conotruncal anomaly. Due to parallel fetal circulation, truncus arteriosus does not cause any haemodynamic problem in utero. However it is a major problem postnatally and, if left untreated, approximately 80% of infants die within the first year. Diagnosis should be made early by radiologists and cardiologists due to fatal illness. We found it valuable to present a case of truncus arteriosus with computerized tomography findings because of its rare occurrence. © 2020 The Authors
Detection of Incidental Findings on Chest Ct Scans in Patients With Suspected Covid-19 Pneumonia
(Yuzuncu Yil Universitesi Tip Fakultesi, 2021) Dündar, İ.; Özkaçmaz, S.; Durmaz, F.; Çoban, L.T.; Aygün, G.; Yıldız, R.; Türkoğlu, S.
This study aimed to evaluate the chest Computed Tomography (CT) scans of COVID-19 suspected patients in the first period of the pandemic, to reveal the frequency of parenchymal-extraparenchymal incidental findings (IFs). Our single-center retrospective observational study was initiated with the approval of the ethics committee. Chest CT records taken during March-August 2020 due to the suspicion of COVID-19 pneumonia were scanned using the imaging archive of our center. The study was conducted with 1540 patients with non-contrast chest CT without prior CT imaging to detect IFs. Histopathological results and clinical-radiological follow-up data of the patients were scanned from medical records. Of the 1540 patients in our study, 902 (58.57%) were male and 638 (41.43%) were female, with a mean age of 41.96±17.08 (5-92) years. While 248 (16.1%) patients had a typical appearance for COVID-19 pneumonia on thorax CT, no findings were found in 1180 (76.6%) patients. Except for COVID-19 pneumonia, parenchymal IFs(primary malignant lung lesions, metastatic lesions, benign pathologies) were detected in 73 patients (4.74%) and extraparenchymal IFs(lymphadenopathy, breast lesions, thyroid nodule, bone, liver and kidney lesions…) in 280 patients (18.8%). Our study showed that the number of patients without any findings in terms of COVID-19 pneumonia on CT scans is high. It is understood that CT scans for pneumonia are unnecessary due to radiation exposure and should be used when clinically necessary. However, due to the ability of CT to detect incidental findings, it is also important to define IFs oth er than pneumonia in patients who underwent chest CT examination during the pandemic. © 2021, Yuzuncu Yil Universitesi Tip Fakultesi.

Radiological Imaging Findings of Avalanche Victims With Traumatic Lesions in Van Eastern Province of Turkey
(Yuzuncu Yil Universitesi Tip Fakultesi, 2021) Özkaçmaz, S.; Dündar, İ.; Çoban, L.T.; İlik, İ.; Durmaz, F.; Çallı, İ.
This study aimed to present the radiological findings of survivors from two avalanches within two days in the same valley. This retrospective descriptive study was carried out in two centers after ethics committee approval. The radiological and demographical findings of 47 survivors were screened from two hospital databases. Patients were classified regarding the type of traumatic lesion as well as the lesion sites. A total of 39 traumatic lesions in 22 patients were detected via radiological imaging modalities. The female/male ratio was 4.8% (1/21) and the mean age was 42.6±17.1 years (24-86 years). Among the 39 traumatic lesions, 13 (33.3%) were detected in the extremities (4 in the muscles/ligaments, 9 in the bones), 9 (23.1%) in the spine (5 transverse, 2 spinous process, and 2 corpus fractures), 9 (23.1%) in the thorax (5 pulmonary contusion, 1 pneumomediastinum, 1 hemothorax, and 2 rib fractures), and 8 (20.5%) in the head (1 subdural hematoma, 5 maxillofacial fractures, and 2 subcutaneous hematomas). There were no abdominal or pelvic lesions detected in this study. Traumatic lesions can be seen in all systems and organs. Results of this study revealed that spinal and extremity fractures and pulmonary contusions were the most commonly reported traumatic lesions in the included av alanche victims. Muscular injuries were also detected. The use of MRI increases the success of lesion detection in intracranial structures and muscular-ligamentous tissues. © 2021, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
A Ruptured Cystic Echinococcosis in the Gallbladder and Intra/Extrahepatic Biliary Tract, Radiological and Surgical Imaging Findings
(Galenos Publishing House, 2023) Türkoğlu, S.; Ekici, A.; Turgut Çoban, L.; Dündar, İ.; Okyay, O.; Gürbüz, E.
Cystic echinococcosis is a common parasitic infestation that can still cause serious complications in endemic areas. Intrabiliary rupture is a well-defined complication, but rupture into the gallbladder is rare. The disease may present with cholecystitis and cholangitis. Clinicians and radiologists working in the emergency room will find the management of the disease much easier if they become familiar with the clinical and radiological findings of the cyst. In this article, a 28-year-old male admitted to the emergency department with acute abdominal pain who was examined for suspected acute cholecystitis and diagnosed with a rupture of the hydatid intra/extrahepatic bile ducts and gallbladder is presented. Our aim is to present the clinical findings and surgical images of the case (ultrasonography, computed tomography, magnetic resonance imaging) and compare them with the literature. © 2023, Galenos Publishing House.
