Purpose The increasing tendency of chest CT usage throughout the COVID-19 epidemic requires new tools and a systematic scheme for diagnosing and assessing the lung involvement in Coronavirus Disease 2019 (COVID-19). To investigate the use of the COVID-19 Reporting and Data System (CO-RADS) classification and chest CT Involvement Score (CT-IS) in COVID-19 pneumonia. Material and methods This retrospective study enrolled 280 hospitalized patients diagnosed with COVID-19 pneumonia in a tertiary hospital in Turkey. All patients underwent non-contrast CT chest imaging. Two radiologists interpreted all CT images according to CO-RADS classification without knowing the clinical features, laboratory findings. We used CT involvement score (CT-IS) for assessing chest CT images of COVID-19 patients. Also, we examined the relationship between CT-IS and clinical outcomes in COVID-19 patients. Results Of the patients, 111(39.6%) had positive real-time reverse transcriptase-polymerase chain reaction (RT-PCR) results. CO-RADS 5 group patients had statistically significant positive RT-PCR results than the other groups (P < 0.001). All of the CO-RADS 2 group patients (30) had negative RT-PCR results. The mean total CT-IS in CO-RADS 2 group was 3.4 ± 2.8. The mean total CT-IS in CO-RADS 5 group was 8.2 ± 4.7. Total CT-IS was statistically significantly different among CO-RADS groups (P < 0.001). The mean total CT-IS was statistically significantly different between survivors and patients died of COVID-19 pneumonia (P < 0.001). Conclusions CO-RADS is useful in detecting COVID-19 disease, even if RT-PCR testing is negative. CT-IS is also helpful as an imaging tool for evaluation of the severity and extent of COVID-19 pneumonia.

Objectives Behcet's disease is a multisystemic, inflammatory disease. Various factors have been implicated in the disease, including genetics, infections, immunoglobulins, immune complexes, antibodies, and oxidative stress. However, the underlying etiopathogenesis remains unclear. Behcet's disease can occur with or without vascular involvement. This prospective study investigated the relationship between the intima-media thickness of the major arteries, in addition to other factors affecting the disease process, in Behcet's disease without vascular involvement. Methods Twenty-four patients (average age: 38.50 ± 10.931) without vascular involvement or any vascular complaints who were diagnosed with Behcet's disease were included in the study. Sixteen healthy subjects (average age: 39.75 ± 7.793) were included as a control group. Demographic information and medical histories were recorded, and routine blood tests were performed in both groups. The intima-media thickness of the subclavian, axillary, femoral, and carotid arteries of all the participants were recorded using Doppler ultrasonography. The data were then subjected to intergroup statistical and correlation analyses. Results There were no significant differences between the arterial intima-media thickness values of the Behcet's disease patients and those of the control group ( p > 0.05). However, there was a significant difference between the neutrophil-lymphocyte ratio ( p = 0.004), low-density lipoprotein ( p = 0.007), and triglyceride ( p = 0042) levels of the two groups. Significant correlations were found between intima-media thickness and neutrophil-lymphocyte ratio levels ( p = 0.012) and the disease duration ( p = 0.030). There was also a significant correlation between the intima-media thickness of the femoral artery and disease duration ( p = 0.014). Conclusions The results showed that the duration of illness had a significant effect on arterial intima-media thickness in Behcet's disease. Blood neutrophil-lymphocyte ratio levels were also associated with increased intima-media thickness.

The “Corona Virus Disease 2019 (COVID-19)”, caused by severe acute respiratory coronavirus 2 (SARS-CoV-2), progressed rapidly since its first outbreak, and quickly developed into a pandemic. Although COVID-19 mostly presents with respiratory symptoms, researchers have started reporting neurologic manifestations such as cerebrovascular diseases in patients, with COVID-19 as the pandemic has progressed. Herein, we report a case of 38-year-old female patient identified with a left common carotid artery dissection, with COVID-19. Clinicians must keep in mind that COVID-19 can cause vascular complications such as carotid artery dissections in the ensuing period, even after the acute phase, although there is currently a lack of sufficient evidence to identify any causal association between COVID-19 and arterial dissections.

ÖZETPrimer apendajitis epiploika (PAE), kolon epiploik apandikslerinin torsiyonu ya da santral venlerinin spontan tombozu nedeniyle meydana gelen ve akut kar›n a¤r›s›na yol açan ender bir hastal›kt›r. Genellikle cerrahi müdahale gerektirmeyen ve kendini s›n›rlayac› özellikte bir hastal›k olsa da, cerrahi giriflimin ya da agresif medikal tedavinin flart oldu¤u apandisit, divertikülit, kolesistit gibi akut kar›n hastal›klar›n› taklit edebilir. Gereksiz cerrahi giriflim ve hastane yat›fllar›n›n önlenmesi için PAE olgular›n›n do¤ru teflhis edilmesi büyük önem tafl›maktad›r. Bu yaz›da, akut kar›n a¤r›s› nedeniyle de¤erlendirilen ve primer apendajitis epiploika tan›s› alan iki olgu sunulmaktad›r.Anahtar Kelimeler: Apendajitis, Apandisit, Divertikülit, Akut kar›n ABSTRACT Primary appendagitis epiploica (PAE) is a rare disease due to torsion or spontaneous thrombosis of the central draining vein of the colon and causes acute abdominal pain. PAE is a self limiting disease and it doesn't usually require surgical intervention. But it can mimic conditions such as appendicitis, diverticulitis, cholecystitis that definitely need surgical interventions or agressive medical treatment. Because of this, the correct diagnose of PAE is very important in order to prevent unnecessary surgical interventions or hospitalisations. In this paper, we present two patients that examined because of acute abdominal pain and then diagnosed with PAE.

: Cystic lymphangioma presenting with multiple bone lesions in an adult patient is a rare occurrence, with a limited number of reported cases in the literature. In this case report, we describe a 32-year old female patient with chronic neck and pelvic pain, and multiple lytic bone lesions on radiological imaging, which were eventually discovered to originate from cystic hygroma and widespread bone lymphangiomas that were present for more than 10 years. It should be kept in mind that there may be benign causes in the differential diagnosis in patients presenting with findings suggestive of diffuse bone metastasis.Because misdiagnosis may cause the patient to receive unnecessary treatments, especially radiotherapy. In this case, we reached the diagnosis of benign disease, diffuse bone lymphangiomatosis, and the long and stable medical history of the patient with the findings of BT, ultrasound and bone scintigraphy. We think that as long as there are no stable and serious results in the company with the clinical and radiological findings of the patient, it should be approached with medical follow-up without treatment.
