To describe the spectrum of imaging findings in pulmonary echinococcosis and to study the additive value of T2-weighted magnetic resonance imaging (MRI) in the characterisation of pulmonary hydatid disease.

This was a descriptive, prospective study conducted for a period of 3 years from December 2016 to November 2019. Patients suspected of having pulmonary echinococcosis (
= 110) on preliminary chest radiography were examined with chest computed tomography (CT). Among them 41 cases were additionally examined with T2-weighted MRI of thorax. Final diagnosis was based on surgery or histopathology.

Of the 110 patients enrolled for the study 15 were lost to attrition, and among the final cohort of 95 patients CT correctly diagnosed 68/84 (80.9%) as hydatid cyst, whereas 16/84 (19.1%) received an erroneous alternate diagnosis on CT. Based on the classical findings of hyperintense pulmonary cystic lesion with T2-weighted hypointense rim or detached internal T2-weighted hypointense membrane, a correct diagnos alternative diagnosis.Iatrogenic brain aneurysms are rare and are usually a result of direct trauma to the arterial wall during various neurosurgical or endovascular procedures. Single cases of pericallosal posttraumatic and postsurgical aneurysms were previously reported. Herein, we report the first confirmed case of iatrogenic pericallosal artery aneurysm caused by an arterial wall injury during the endovascular treatment of another aneurysm. A 50-year-old woman with ruptured anterior communicating artery aneurysm was initially treated with balloon-assisted coiling. During the procedure the tip of a microwire inserted into balloon catheter placed in the pericallosal artery caused a local injury of the inner layer of the vessel wall and vasoconstriction, without bleeding, dissection, or flow disturbances visible in digital subtraction angiography (DSA). Control examination revealed dissecting pericallosal aneurysm. After standard dual-antiplatelet oral preparation, stent-assisted coiling of the pericallosal artery aneurysm was performed with residual contrast filling of the base of the aneurysm sac in control angiography (RROC III). After 6 months the control DSA examination showed entirely cured pericallosal aneurysm (RROC I) and reconstruction of the parent artery. Successful endovascular treatment of an iatrogenic pericallosal aneurysm was previously reported, and this method seems to be the first-choice treatment. In our case, endovascular stent-assisted coiling also allowed for safe exclusion from circulation of pericallosal dissecting aneurysm, and the implanted stent caused reconstruction of the parent artery, restoring the normal lumen diameter. The second endovascular treatment option considered was implantation of a flow-diverted stent into the pericallosal artery.
Numerous cases of pneumonia caused by coronavirus disease 2019 (COVID-19) were reported in Wuhan, China. Chest computed tomography (CT) scan is highly important in the diagnosis and follow-up of lung disease treatment. The present meta-analysis was performed to evaluate chest CT scan findings in COVID-19 patients.

All research steps were taken according to the Meta-Analysis of Observational Studies In Epidemiology (MOOSE) protocol and the final report was based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We registered this review at the International Prospective Register of Systematic Reviews (PROSPERO, CRD42019127858).

Forty eligible studies including 4598 patients with COVID-19 were used for meta-analysis. The rate of positive chest CT scan in patients with COVID-19 was 94.5% (95% CI 91.7-96.3). Bilateral lung involvement, pure ground-glass opacity (GGO), mixed (GGO pulse consolidation or reticular), consolidation, reticular, and presence of nodule findinstandard method for diagnosis of COVID-19.
The most important outcomes in chest CT scan of patients with COVID-19 pneumonia were bilateral lung involvement, GGO or mixed (GGO pulse consolidation or reticular) patterns, thickened interlobular septa, vascular enlargement, air bronchogram sign, peripheral distribution, and left and right lower lobes involvement. Our study showed that chest CT scan has high sensitivity in the diagnosis of COVID-19, and may therefore serve as a standard method for diagnosis of COVID-19.
The impact of computed tomography (CT)-guided, percutaneous radiofrequency ablation and interstitial laser ablation (ILA) on the management of patients with osteoid osteoma was studied. This was carried out by assessing immediate and long-term clinical outcomes, the complication rate, and repeat therapy effectiveness in recurrent patients who have already experienced percutaneous ablation.

Consecutive patients with osteoid osteoma were assessed before the interventional treatment in a single centre from 2010 to 2015. Patient demographics, complications, and recurrence were recorded. The pain was evaluated with Visual Analogue Scale (VAS). Percutaneous procedures were performed by means of radiofrequency thermoablation or ILA. Epidural or regional anaesthesia in the CT suite was applied in all procedures. Success, whether primary or secondary, was measured as complete pain relief without evidence of recurrence after the first or second procedure, respectively. Bupivacaine Osteoid osteoma characteristics, procedure ovehieving primary and secondary treatment success.Coronavirus disease (COVID-19), caused by a highly contagious novel coronavirus, has seen a rapid surge of cases over the past 6 months spreading to more than 215 countries and posing a global threat to mankind. Reverse transcriptase-polymerase chain reaction (RT-PCR) from pharyngeal swabs is considered the gold standard for diagnosis of this disease. Portable chest radiography (CXR), point of care ultrasound, and computed tomography (CT) are crucial modalities in diagnosis and follow-up. Portable CXR can help in patients who are clinically unstable, and also to prevent the cumbersome process of steriliastion after every CT scan. However, chest CT is useful as a problem-solving tool, to look for progression and complications associated with the disease. In a few cases, in our experience (as has also been documented by others), RT-PCR was negative in early disease, and CT chest was able to detect the radiologi-cal findings raising suspicion of COVID-19. With this pictorial review, we aim to describe and illustrate the typical, and a few atypical, radiological findings of this disease.
