A suggestive case report of acute mesenteric venous thrombosis diagnosed at Computed Tomography Angiography.

Acute mesenteric venous thrombosis (MVT) is a rare but potentially fatal condition with superior mesenteric vein being the most common site of thrombosis development. It is more common in patients with underlying disorders which cause disruptions to Virchow's Triad of hypercoagulability, stasis and endothelial injury. The disease is often associated with intestinal ischemia in its acute form, further complicating its management.

A simultaneous superior mesenteric arterial and venous thrombosis in an elderly woman with a previous COVID-19 pneumonia: A suggestive case report diagnosed at computed tomography angiography.

Superior mesenteric artery (SMA) and superior mesenteric vein (SMV) thrombotic occlusion is a rare but potentially fatal condition. Though isolated mesenteric arterial occlusion associated with COVID-19 has been reported in literature, combined superior mesenteric arterial and venous thrombosis is very rare. We report the case of an 88-years-old woman with a combined superior mesenteric arterial and venous thrombotic occlusion with a previous COVID-19 pneumonia of about 15 days before, diagnosed at computed tomography angiography (CTA) scan.

Acute aortic dissection in a young man with bilateral Covid-19 pneumonia: A suggestive case report at Computed Tomography Angiography.

Acute Aortic Dissection (AAD) is one of the most common lifethreatening diseases that affects the aortic vessel. An its immediate and accurate diagnosis is crucial to initiate the appropriate treatment. The Covid-19 Coronavirus infectious pandemic started since December 2019 and was declared a pandemic by the World Health Organization in March 2020.

A fuzzy-enhanced deep learning approach for early detection of Covid-19 pneumonia from portable chest X-ray images.

The Covid-19 pandemic is the defining global health crisis of our time. Chest X-Rays (CXR) have been an important imaging modality for assisting in the diagnosis and management of hospitalised Covid-19 patients. However, their interpretation is time intensive for radiologists.

Retroperitoneal hematoma by different causes: Presentation of two emergency cases at computed tomography.

Retroperitoneal hematoma is a rare clinical entity with variable aetiology, which is increasing in incidence mainly due to complications related to interventional procedures. The causes of RE are different. We present 2 suggestive cases of RE, one for renal cause and another of adrenal origin.

Pericardial and pleural effusion in an elderly woman with Covid-19 pneumonia: CT findings.

Coronavirus-19 disease is an acute respiratory syndrome infection that primarily infects the lungs, and may extend to other organs such as the cardiovascular system. Here we describe the case of a 90-year-old woman, affected by heart failure (NYHA, class III), with bilateral Covid-19 pneumonia, complicated by pleural and pericardial effusion. An unenhanced Computed Tomography, urgently made, allowed to hospitalize and treat the patient, monitoring her clinical situations.

A pulmonary hamartoma in Covid-19 pneumonia: an interesting case studied with computed tomography.

Since the widespread of acute respiratory syndrome infection caused by Coronavirus-19, chest computed tomography (CT) was considered a useful imaging tool commonly used in early diagnosis and monitoring of patients with complicated Covid-19 pneumonia. Many typical imaging features of this disease were carefully described with chest CT, as well as the collateral CT findings in the lungs and mediastinum. Here we describe the case of a patient with Covid-19 pneumonia, that collaterally had a pulmonary hamartoma in the left lung, documented at CT.

The spider web sign in Covid-19 pneumonia: An interesting case studied to resolution with computed tomography.

Since the widespread of acute respiratory syndrome infection caused by Coronavirus-19, unenhanced computed tomography (CT) was considered a useful imaging tool commonly used in early diagnosis and monitoring of patients with complicated Covid-19 pneumonia. Many typical imaging features of this disease were described such as bilateral multilobar ground-glass opacity (GGO) with a prevalent peripheral or posterior distribution, mainly in the lower lobes, and sometimes consolidative opacities superimposed on GGO. As less common findings were mentioned septal thickening, bronchiectasis, pleural thickening, and subpleural involvement.

Bilateral acute pulmonary embolism and Covid-19 pneumonia: CT findings.

Since the widespread of acute respiratory syndrome infection caused by coronavirus-19, unenhanced computed tomography (CT) was considered a useful imaging tool commonly used in early diagnosis and monitoring of patients with complicated Covid-19 pneumonia. If there is clinical or laboratory suspicion of pulmonary embolism complicating Covid-19 pneumonia, CT angiogram of the pulmonary arteries may be necessary. Here we describe the case of a 52 years old man, affected by a high-risk myelodysplastic syndrome patient, with Covid-19 pneumonia, complicated by a bilateral massive acute pulmonary embolism.

Gallstone obstruction at the proximal ileum in an elderly woman: CT findings.

We present the case of a 73 years old woman with intestinal obstruction caused by a rare cause of biliary ileus, who arrived at our emergency department with lower abdominal quadrants pain (since about 2 months), recently associated with nausea, vomiting and abdominal distension. After clinical and laboratory evaluations, a computed tomography (CT) scan without intravenous contrast medium administration was urgently requested. CT had shown the presence of a large gallstone (diameter of about 6 cms) at the proximal ileum (stopped in this tract after the passage through a biliary-enteric fistula), and another gallstone (diameter of about 2 cms) in the gallbladder, associated with concentric thickening of gallbladder's walls, gas in the biliary tree, obliteration of peri-gallbladder's fat density and fluid in the peri-subhepatic area.
