Bu çalışmada COVID-19 tanısı alan hastaların toraks bilgisayarlı tomografi (BT) sonuçlarını inceleyip, tipik ve atipik bulguları literatür eşliğinde sunmayı amaçladık.Araçlar ve Yöntem: Hastanemize mart ve nisan aylarında başvuran ve reverse transkriptaz-polimeraz zincir reaksiyonu (RT-PZR) ile COVID-19 tanısı alan hastaların toraks BT'leri retrospektif olarak değerlendirildi. Akciğer parankim bulgularından buzlu cam sahaları, konsolidasyon, vasküler genişleme, fibrozis, nodül, septal kalınlaşma (crazy paving), ters halo, plevral effüzyon ve mediastinal LAP bulguları araştırıldı. Parankimdeki tutulum yerine göre bilateral-unilateral, periferik-santral, üst-orta-alt loblardaki odak sayılarına göre lezyonların dağılımı değerlendirildi.Bulgular: PCR pozitif olan 53 hastanın (ortalama yaş 48,38±20,97) 14'ünde (% 26) toraks BT'de bulgu yoktu. BT'de bulgusu olan 39 hastada (%74), tipik bulgulardan buzlu cam sahası (%85), konsolidasyon (%56), buzlu cam ve konsolidasyon birlikteliği (%59), vasküler genişleme (%28) izlendi. Atipik bulgulardan nodül (%20), septal kalınlaşma (%30), fibrozis (%10), plevral efüzyon (%8), hava bronkogramı (%18), ters halo bulgusu (%5) saptandı. Hastalarımızda mediastinal LAP saptanmadı. Toraks BT'de bilateral, orta ve alt zonlarda periferik yerleşimli multifokal odaklar tipik tutulum şekliydi. 14 hastada toraks BT negatif olup herhangi bir bulguya rastlanmadı.Sonuç: Toraks BT, COVID-19 hastaları için tanıya yardımcı çok önemli bir yöntem olup parankim tutulumunun tipik ve atipik bulgular şeklinde kategorize edilerek değerlendirilmesi tanı sürecini kolaylaştırabilir.

Os calcaneus secundarius is one of several accessory ossicles of the foot that have been identified as normal variants of skeletal development. It may cause ankle pain and may mimic an avulsion fracture of the anterior calcaneal process. A twenty-year-old male was admitted to our institution with right ankle pain following an inversion injury. An axial CT image of the patient's right ankle revealed a shape with smooth and sharp margins, identified as a well-corticated bone fragment in the subtalar region. A diagnosis of an accessory ossicle, os calcaneus secundarius, was made based on radiographic findings. As a result of this case, it is recommended that potential locations of the accessory bones should be well understood in order to prevent misdiagnosis and inappropriate surgical procedures. Os calcaneus secundarius must be considered when an apparent bone fragment or a suspicious fracture line at the anterior region of os calcaneus is demonstrated.

Gradenigo syndrome is associated with middle ear infection that extends to the petrous apex, leading to pain at the innervation site of the ophthalmic and maxillary branches of the trigeminal nerve and the development of abducens nerve palsy. Cerebral venous sinus thrombosis is a serious neurological complication of otitis media and occurs secondary to spread of the infection to the underlying bone. We herein report a pediatric case of otitis media associated with Gradenigo syndrome and ipsilateral sigmoid–transverse sinus thrombosis with magnetic resonance imaging findings.

Background Determining the nature of purely cystic hepatic lesions is essential because different kinds have different follow-ups, treatment options, and complications. Purpose To explore the potential of apparent diffusion coefficient (ADC) values of diffusion-weighted imaging (DWI) for the differentiation of type I hydatid cysts (HC) and simple liver cysts (SLC), which have similar radiological appearances. Material and Methods This single-center prospective study was conducted during 2016–2019. Round, homogenous, anechoic liver cysts >1 cm were classified according to at least two years of imaging follow-up, radiological features, serology, as well as puncture aspiration injection reaspiration procedure and pathology results. ADC values of 95 cysts (50 type I HCs and 45 SLCs) were calculated on DWI. The differences in ADC values were analyzed by independent t-test. Results Of 51 patients, 28 were female, 23 were male (mean age 32.07 ± 22.95 years; age range 5–82 years). Mean diameter of 45 SLCs was 2.59 ± 1.23 cm (range 1.2–7.6 cm) and ADCmean value was 3.03 ± 0.47 (range 2.64–5.85) while mean diameter of 50 type I HCs was 7.49 ± 2.95 cm (range 2.8–14 cm) and ADCmean value was 2.99 ± 0.29 (range 2.36–3.83). There was no statistically significant difference in ADC values between type I HCs and SLCs Conclusion Some studies report that ADC values of type I HCs are statistically significantly lower than those of SLCs. Others suggest no significant difference. In our study with a higher number of cases, using ADC parameters similar to those in previous studies, we did not find any statistically significant difference.

Pelvic lipomatosis is an uncommon disease with no clear etiology and it occurs secondary to deposition of a large amount of fatty tissue in the pelvis. This deposition causes compression to the rectum, bladder, and venous structures. Because of this compression, various symptoms, such as recurrent urinary infections, dysuria, tenesmus, and constipation, have mostly been reported. However, iliac or superior vena cava thrombosis secondary to vascular compression of pelvic lipomatosis is rare. This report describes a case of pelvic lipomatosis, which was associated with right-sided mild hydronephrosis and portal vein thrombosis.

Totally implantable venous access systems are widely used in oncology; however, their complications are extremely common whic h, sometimes, require device removal, thereby, leading to delayed chemotherapy and infusion therapies. In this study, we aimed t o investigate the immediate, early, and late complications of venous port implantation in our oncology patients. A total of 219 consecutive cancer patients (111 males, 108 females; mean age: 56.9 years; range: 1 to 81 years) were retrospe ctively analyzed between January 2013 and June 2014. A total of 220 ultrasound-and fluoroscopy-guided totally implantable venous port systems were implanted through the right or left internal jugular vein access. The mean follow-up was 83.7 (range: 2 to 410) days. Overall c omplication rate was 8.6% (19/220). Eight devices in seven patients were removed due to complications. Two ports were removed in one patient. The complications which required port removal were compromised port-related bloodstream infection (n=5), central venous thrombosis (n=3), and catheter thrombosis (n=1). No major complication or no mortality associated with the port implantation was seen during follow-up. Totally seven immediate complications including local hematoma (n=2), catheter tip retraction (n=2), pain (n=1), catheter loop formation (n=1), catheter malposition (n=1), two early complications (n=2; 1 wound dehiscence, and 1 wound infection), and 10 late complications including catheter-related blood stream infection (n=5), central venous thrombosis (n=3), catheter thrombosis (n=1), and tunnel hematoma (n=1) occurred. Low incidence of complications suggest ultrasound-and fluoroscopy-guided venous port implantation is a safe and reliable method for long-term venous access
