ABSTRACT

Hepatocellular Carcinoma (HCC) is the sixth most common cancer in the world. Patients with intermediate stage (Barcelona Clinic Liver Cancer, B stage) hepatocellular carcinoma (HCC) have been able to benefit from TACE (transarterial chemoembolization) as a treatment option. MicroRNAs (miRNAs), i.e., a subclass of non-coding RNAs (ncRNAs), participate in post-transcriptional gene regulation processes and miRNA dysfunction has been associated with apoptosis resistance, cellular proliferation, tumor genesis, and progression. Only a few studies have investigated the role of miRNAs as biomarkers predicting TACE treatment response in HCC. Here, we review the studies' characteristics from a radiological point of view, also correlating data with radiological images chosen from the cases of our institution.

ABSTRACT

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.

ABSTRACT

PURPOSE: The aim of this observational study was to highlight high resolution CT scan characteristics of COVID-19-associated pulmonary aspergillosis (CAPA) with a focus on the detection of de-novo appeared or evolved bronchiectasis. METHODS: From March 2020 to May 2021, we enrolled 350 consecutive mechanically ventilated ICU patients with COVID-19. Patients with CAPA and at least one chest CT scan performed within 15 days from the diagnosis were included. Two radiologists were asked to identify typical and atypical signs of COVID-19 pneumonia. Bronchiectasis locations were described and a modified Reiff score was calculated, as severity score. A total of 19 CAPA patients (median age 71.0, Interquartile range (IQR) 62.5-75.0; male 16, 84.2%) were included. RESULTS: According to the 2020 ECMM/ISHAM criteria, 18 patients had probable CAPA and one had proven CAPA. The median time between hospital admission and CT scan was 21 days (IQR 14.5-25.0). The incidence of bronchiectasis in the study population was 57.9% (n = 11). Tubular bronchiectasis was detected in 10 patients and were scored as follows: three patients had a score of 1, three patients had a score of score 2, one patient had a score of 5 and four patients had a score of 6. Eight patients had a previous CT scan (performed at hospital admission), among them: 5 patients developed de-novo bronchiectasis, while 2 patients demonstrated a volumetric increase of bronchiectasis. At the 6-months follow-up, the mortality rate for patients with CAPA was >60%. CONCLUSION: the radiologic detection of de-novo appearance or volumetric increase of bronchiectasis in COVID-19 should lead clinicians to search for fungal superinfections.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is mostly perceived as a respiratory disease. However, there is increasing evidence of patients showing gastrointestinal symptoms, with increasing rates of presentation according to the severity of the disease. In a few cases, the abdominal involvement of COVID-19 resulted in spontaneous bowel perforation. Here, we present in detail the first case of rectal perforation in a patient with COVID-19.
