This study aimed to investigate the prevalence of persistent trigeminal arteries (PTAs) using computed tomography (CT) angiography, emphasize its major characteristics, and compare the ndings with those reported in the relevant literature. MethodsPatients who underwent cerebral CT angiography in our radiology clinic for any preliminary diagnosis between December 2013 and December 2020 were included in this retrospective study. The patients were reviewed in terms of their age, sex, and the presence of PTAs. The localization of the PTA, vascular connection, PTA type (according to Saltzman and Salas classi cation), and vascular pathology at the level of anastomoses were examined in the patients with PTAs. ResultsA total of 1150 patients, (632 [55%] males and 518 [45%] females) were included in this study. A total of seven (0.6%) patients had PTAs. PTAs were located on the right and left sides in 3 (43%) and 4 (57%) patients, respectively. A total of 3 (43%), 2 (28%), and 2 (28%) cases were classi ed as types I, II, and III PTA based on the Saltzman classi cation, respectively. Moreover, 4 (57%) and 3 (43%) cases were lateral and medial types based on the Salas classi cation, respectively. ConclusionIn conclusion, understanding the diagnosis and classi cation of PTAs is crucial for the diagnosis of possible vascular pathologies by neuroradiologists and physicians performing neurovascular interventional procedures or operations. If these vascular pathologies remain undetected, they may cause fatal bleeding or embolism during surgeries and endovascular procedures.

Background and objective CT imaging is important in detecting the location and the structure of swallowed foreign bodies and assessing their complications, due to its features such as the ability to show the detailed anatomical structure and enable multiplanar examination. In this study, we aimed to analyze the CT findings of swallowed foreign bodies located in the gastrointestinal tract and compare them with the data in the existing literature. Materials and methods We conducted a retrospective archive study to achieve our goals. Patients who presented to our radiology department with the preliminary diagnosis of foreign body ingestion, abdominal pain, or acute abdomen and were found to have a foreign body in the gastrointestinal tract on CT between April 2018 and April 2021, especially those in whom the presence of a foreign body was confirmed by endoscopy or surgery, were included in our study. The patients were evaluated in terms of age, gender, foreign body type, foreign body localization, and complications. Results A total of 31 patients (15 males and 16 females) were included in the study. The patients’ age ranged from 1 to 67 years, and the mean age was 28.5 ±5.4 years. The most common foreign bodies found were metallic toy parts (n=11, 35%), and most of the foreign bodies were located in the ileum (n=9, 29%) of the patients. Complications were observed in nine patients (29%). In patients with complications, the most common finding was perforation (n=3, 38%). Conclusion When a CT exam is performed on patients with abdominal pain, the gastrointestinal tract should be carefully evaluated to determine if a foreign body is involved and to analyze the complications caused by the foreign body.

Background: Focal cortical dysplasia (FCD) is a condition that often interferes with the cranial mass. Knowledge of focal cortical dysplasia magnetic resonance imaging (MRI) characteristics is of utmost importance for diagnosis. This study aimed to determine the diagnostic contribution of cranial MRI and the apparent diffusion coefficient (ADC) in FCD. Results: Cranial MRI revealed subcortical hyperintensity (SCH) in 52 patients (82.5%), blurring of the gray-white matter (GWM) interface (blurring) in 52 patients (82.5%), cortical thickening (CT) in 48 patients (76%), cortical signal increase (CSI) in 41 patients (65%), and transmantle sign (TMS) in 29 patients (46%). All of the FCDs had a diffusion increase in diffusion-weighted images (DWIs). The mean ADC value at the lesion level was 1.087 × 10 −3 mm 2 /s (0.82/1.316 × 10 −3 mm 2 /s), which was significantly higher than the mean ADC value measured from the contralateral symmetric region (0.758 × 10 −3 mm 2 /s, 0.678/0.872 × 10 −3 mm 2 /s, p = 0.001). Conclusion: Results of this study revealed that the most common MRI findings in FCD patients are SCH, blurring, and CT. These findings aid in an easier diagnosis in patients with suspected FCD. All of the lesions studied here in had a diffusion increase in DWI. The quantitative mean ADC values detected in the differential diagnosis of other lesions with a diffusion increase can be used as a reference. Therefore, in addition to the ADC values and electroencephalography (EEG) findings, the conventional MRI findings of FCD, which is resistant to medical treatment, can help to facilitate the diagnosis of FCD, which can be treated with surgery.

Bu çalışmada benign lezyonlar olan meme hamartomlarının (MH) radyolojik görüntüleme özelliklerini ele almak ve hamartom lezyonlarının tanınabilirliğini vurgulayarak gereksiz tetkik ve biyopsilerin azaltılmasına katkıda bulunmak amaçlanmıştır. Gereç ve Yöntemler: Ocak 2014-Temmuz 2019 döneminde Dicle Üniversitesi Tıp Fakültesi radyoloji kliniğimizde MH tanısı almış olan toplam 33 (32 kadın, 1 erkek) hastanın mamografi (MG), ultrason (US) ve manyetik rezonans görüntüleme (MRG) görüntüleri retrospektif olarak incelendi. Altı hastanın MG, US ve MRG, 21 hastanın MG ve US, 6 hastanın ise sadece MRG görüntüleri mevcuttu. Erkek hasta için MG ve US görüntüleri mevcuttu.Bulgular: Ortalama hasta yaşı 48,5 (28-74) yıldı. Ortalama kitle boyutu 3,4 (1,5-12) cm idi. En büyük kitle jinekomasti ön tanısı ile başvuran erkek hastada olup sağ memeyi tamamen kaplamıştı. Lezyonlar 20 hastada sağ, diğer 13 hastada sol meme yerleşimliydi. MRG görüntüleri incelendiğinde postkontrast görüntülerde lezyonların tamamında periferal ağırlıklı heterojen kontrastlanma mevcutken kontrastlı serilerde 10 hastada tip 1, 2 hastada tip 2 kinetik eğri mevcuttu. Hiçbir hastada tip 3 kinetik eğri saptanmadı. Difüzyon MRG'de normal meme dokusu görünür difüzyon katsayısı (GDK) değeri ile hamartom GDK değeri arasında istatistiksel olarak anlamlı fark bulunmadı (p>0,5). Tartışma ve Sonuç: Benign lezyonlar olan MH'ler radyolojik incelemelerde memeye benzer özellikte küçük nodüler lezyonlar şeklinde izlenirler ve bu özellikleriyle "meme içinde meme" görünümü verdiklerinden kolaylıkla tanınabilirler.
