Objective: To investigate the diagnostic accuracy of a chest X-ray (CXR) score and of clinical and laboratory data in predicting the clinical course of patients with SARS coronavirus 2 (SARS-CoV-2) infection. Methods: This is a pilot multicenter retrospective study including patients with SARS-CoV-2 infection admitted to the ERs in three hospitals in Italy between February and March of 2020. Two radiologists independently evaluated the baseline CXR of the patients using a semi-quantitative score to determine the severity of lung involvement: a score of 0 represented no lung involvement, whereas scores of 1 to 4 represented the first (less severe) to the fourth (more severe) quartiles regarding the severity of lung involvement. Relevant clinical and laboratory data were collected. The outcome of patients was defined as severe if noninvasive ventilation (NIV) or intubation was necessary, or if the patient died. Results: Our sample comprised 140 patients. Most of the patients were symptomatic (132/138; 95.7%), and 133/140 patients (95.0%) presented with opacities on CXR at admission. Of the 140 patients, 7 (5.0%) showed no lung involvement, whereas 58 (41.4%), 31 (22.1%), 26 (18.6%), and 18 (12.9%), respectively, scored 1, 2, 3, and 4. In our sample, 66 patients underwent NIV or intubation, 37 of whom scored 1 or 2 on baseline CXR, and 28 patients died. Conclusions: The severity score based on CXR seems to be able to predict the clinical progression in cases that scored 0, 3, or 4. However, the score alone cannot predict the clinical progression in patients with mild-to-moderate parenchymal involvement (scores 1 and 2). RESUMO Objetivo: Investigar a acurácia diagnóstica de um escore de radiografia de tórax (RxT) e também de dados clínicos e laboratoriais na previsão da evolução clínica de pacientes com infecção por SARS coronavirus 2 (SARS-CoV-2). Métodos: Estudo piloto multicêntrico retrospectivo incluindo pacientes com infecção por SARS-CoV-2 internados nos PSs de três hospitais na Itália entre fevereiro e março de 2020. Dois radiologistas avaliaram as RxT iniciais dos pacientes de forma independente utilizando um escore semiquantitativo para determinar a gravidade do comprometimento pulmonar: escore 0 representava ausência de comprometimento pulmonar, enquanto escores de 1 a 4 representavam o primeiro (menos grave) ao quarto (mais grave) quartil de gravidade do comprometimento pulmonar. Coletaram-se dados clínicos e laboratoriais relevantes. O desfecho dos pacientes foi definido como grave se foi necessária ventilação não invasiva (VNI) ou intubação ou se o paciente faleceu. Resultados: Nossa amostra foi composta por 140 pacientes. A maioria era sintomática (132/138; 95,7%), e 133/140 (95,0%) apresentavam opacidades na RxT da admissão. Dos 140 pacientes, 7 (5,0%) não apresentavam comprometimento pulmonar, enquanto 58 (41,4%), 31 (22,1%), 26 (18,6%) e 18 (12,9%), respectivamente, receberam escore 1, 2, 3 e 4. Em nossa amostra, 66 pacientes foram submetidos a VNI ou intubação, 37 dos quais receberam escore 1 ou 2 na RxT inicial, e 28 pacientes faleceram. Conclusões: O escore de gravidade baseado em RxT parece ser capaz de prever a evolução clínica em casos com escore 0, 3 ou 4. No entanto, o escore isoladamente não consegue prever a evolução clínica de pacientes com comprometimento leve a moderado do parênquima (escores 1 e 2).

Critically ill patients admitted to the intensive care unit require continuous monitoring of vital functions as well as mechanical and pharmacological support, provided through different devices. Chest radiographs play a fundamental role in monitoring the conditions of these patients and assessing the intensive-care devices after their insertion; therefore, the radiologist needs to know their normal appearance and their correct position and should be aware of the possible complications that may occur after their placement. This pictorial review illustrates the radiographic appearance of non-cardiological devices commonly used in clinical practice (central venous catheters, tunneled catheters, Swan-Ganz catheters, chest tubes, endotracheal tubes, and nasogastric tubes), their correct position and the most common complications that may occur after their placement.

Background: Anticoagulant prophylaxis is part of the standard management of hospitalized COVID-19 patients. Despite adequate thromboprophylaxis, one-third of COVID-19 patients with pneumonia developed pulmonary embolism. This high rate of thrombotic complications has led to higher doses of anticoagulants according to clinical complexity (e.g. intensive care unit (ICU) patients) and D-dimer levels. On the other side of the coin, haemorrhagic complications are being increasingly reported. Cases presentation: We herein report four cases of spontaneous psoas haematomas (SPH) among 548 patients hospitalized for SARS-CoV-2 pneumonia between March 2020 and January 2021 (incidence of 7.3 cases per 1000 patients). All patients had pneumonia, with age ranging between 62 and 83 years. All patients received anticoagulant therapy with low weight molecular heparin (100 U.I. anti-Xa/kg 2 times/d) from admission: in two cases, a diagnosis of pulmonary embolism was made. In another case, a thrombosis of left axillary and basilic veins was found, and only in one case anticoagulant therapy was started because of elevated levels of D-dimer. In all cases, signs of anaemia were detected and patients experienced low back or abdominal pain. The diagnosis of spontaneous psoas haematoma was made by computed tomography (CT) after a median of 12.5 d (9;16) from admission and 19.5 d (14.75; 24.25) from the beginning of COVID-19 symptoms. Half of these patients died from haemorrhagic shock. Conclusions: Given the potential life-threatening of SPH and the possible subtle clinical presentation, we believe it is crucial to raise clinicians awareness of this complication among COVID-19 patients undergoing anticoagulants.

Purpose: To assess the diagnostic accuracy of traditional chest X-ray (CXR) and digital tomosynthesis (DTS) compared to computed tomography (CT) in detecting pulmonary interstitial changes in patients having recovered from severe COVID-19. Materials and Methods: This was a retrospective observational study, and received local ethics committee approval. Patients suspected of having COVID-19 pneumonia upon emergency department admission between 1 March and 31 August 2020, and who underwent CXR followed by DTS and CT, were considered. Inclusion criteria were as follows: (1) patients with previous SARS-CoV-2 infection proven by a positive RT-PCR on nasopharyngeal swabs performed upon admission to the hospital, and with complete clinical recovery; (2) a diagnosis of SARS-CoV-2-related ARDS, according to the Berlin criteria, during hospitalization; (3) no recent history of other lung disease; and (4) complete imaging follow-up by CXR, DTS, and CT for at least 6 months and up to one year. Analysis of DTS images was carried out independently by two radiologists with 16 and 10 years of experience in chest imaging, respectively. The following findings were evaluated: (1) ground-glass opacities (GGOs); (2) air-space consolidations with or without air bronchogram; (3) reticulations; and (4) linear consolidation. Indicators of diagnostic performance of RX and digital tomosynthesis were calculated using CT as a reference. All data were analyzed using R statistical software (version 4.0.2, 2020). Results: Out of 44 patients initially included, 25 patients (17 M/8 F), with a mean age of 64 years (standard deviation (SD): 12), met the criteria and were included. The overall average numbers of findings confirmed by CT were GGOs in 11 patients, lung consolidations in 8 patients, 7 lung interstitial reticulations, and linear consolidation in 20 patients. DTS showed a significantly higher diagnostic accuracy compared to CXR in recognizing interstitial lung abnormalities—especially GGOs (p = 0.0412) and linear consolidations (p = 0.0009). The average dose for chest X-ray was 0.10 mSv (0.07–0.32), for DTS was 1.03 mSv (0.74–2.00), and for CT scan was 3 mSv. Conclusions: According to our results, DTS possesses a high diagnostic accuracy, compared with CXR, in revealing lung fibrotic changes in patients who have recovered from COVID-19 pneumonia.
