Pulmonary thromboembolism in critical ill COVID-19 patients.

• COVID-19 in critically ill patients causes death not only from pneumonia but also from multiple organ injuries. • In critically ill COVID-19 patients with pneumonia, pulmonary thromboembolism may be considered. • In critically ill COVID-19 patients, contrast-enhanced computed tomography of the chest is mandatory to assess parenchymal patterns and to diagnose pulmonary thromboembolism.

Split-Bolus Multidetector-Row Computed Tomography Technique for Characterization of Focal Liver Lesions in Oncologic Patients.

Background: In oncologic patients, the liver is the most common target for metastases. An accurate detection and characterization of focal liver lesions in patients with known primary extrahepatic malignancy are essential to define management and prognosis.

Objectives: To assess the diagnostic accuracy of the split-bolus multidetector-row computed tomography (MDCT) protocol in the characterization of focal liver lesions in oncologic patients.

Split-Bolus Single-Pass Multidetector-Row CT Protocol for Diagnosis of Acute Pulmonary Embolism.

Background: Currently computed tomography pulmonary angiography (CTPA) has become a widely accepted clinical tool in the diagnosis of acute pulmonary embolism (PE).

Objectives: To report split-bolus single-pass 64-multidetector-row CT (MDCT) protocol for diagnosis of PE.

Patients And Methods: MDCT split-bolus results in 40 patients suspicious of PE were analyzed in terms of image quality of target pulmonary vessels (TPVs) and occurrence and severity of flow-related artifact, flow-related artifact, false filling defect of the pulmonary veins and beam hardening streak artifacts.

Split-bolus versus triphasic multidetector-row computed tomography technique in the diagnosis of hepatic focal nodular hyperplasia: a case report.

Introduction: Computed tomography and magnetic resonance imaging are able to demonstrate and to diagnose hepatic focal nodular hyperplasia when a typical pattern of a well-circumscribed lesion with a central scar is present.Our aim is to propose the split-bolus multidetector-row computed tomography technique as an alternative to the conventional triphasic technique in the detection and characterization of focal nodular hyperplasia to reduce the radiation dose to the patient.To the best of our knowledge, this is the first report regarding the application of the split-bolus computed tomography technique in the evaluation of hepatic focal nodular hyperplasia.

Detection and characterization of focal liver lesions by split-bolus multidetector-row CT: diagnostic accuracy and radiation dose in oncologic patients.

Aim: To assess the diagnostic accuracy and radiation dose of split-bolus multidetector-row computed tomography (MDCT) protocol in the detection and characterization of focal liver lesions in oncologic patients.

Patients And Methods: We retrospectively analyzed triphasic CT at initial diagnosis and follow-up split-bolus 64-detector row CT protocol in 48 oncologic patients with focal liver lesions. Split-bolus MDCT protocol by i.

Detection of small (≤ 2 cm) pancreatic adenocarcinoma and surrounding parenchyma: correlations between enhancement patterns at triphasic MDCT and histologic features.

Background: The aim is to assess the time-density curves (TDCs) and correlate the histologic results for small (≤ 2 cm) PDA and surrounding parenchyma at triphasic Multidetector-row CT (MDCT).

Methods: Triphasic MDCT scans of 38 consecutive patients who underwent surgery for a small PDA were retrospectively reviewed. The TDCs were analyzed and compared with histologic examination of the PDA and pancreas upstream/downstream in all cases.

Giant benign solitary fibrous tumour of the pleura (> 15 cm): role of radiological pathological correlations in management. Report of 3 cases and review of the literature.

Objectives: Solitary fibrous tumour pleura (SFTP) is a localized tumour arising from the submesothelial areolar mesenchyme. In the present study, we defined "giant" lesions with diameter greater than 15 cm. We have studied the role of radiological-histological correlations of three cases in the management of the disease with review of the literature.

Middle ear metastasis from dormant breast cancer as the initial sign of disseminated disease 20 years after quadrantectomy.

We describe an unusual case of breast cancer metastatic to the middle ear in a 71-year-old woman. The metastasis was the initial sign of disseminated disease 20 years after the patient had undergone a quadrantectomy for her primary disease. Computed tomography (CT) demonstrated the presence of an intratympanic mass with a soft-tissue density that was suggestive of chronic inflammation.

Accurate histological terminology for small intestine carcinoid tumors.

The recent WHO Classification of Tumours of the Digestive System reflects the views of a Working Group that convened for an Editorial and Consensus Conference at the International Agency for Research on Cancer (IARC), Lyon, 10 December 2009 [1]. In this classification, the “neuroendocrine neoplasms of the small intestine” include neuroendocrine tumor (NET), neuroendocrine carcinoma (NEC), mixed adenoneuroendocrine carcinoma, EC cell, serotonin-producing NET, gangliocytic paraganglioma, gastrinoma, L cell, glucagon-like peptide-producing, PP/PYY-producing NETs, and somostatin-producing NET. “Carcinoid tumor” is the generic term traditionally applied to low-grade malignant neoplasms originating from the diffuse endocrine system exclusive of the pancreas and the thyroid C-cell, a term being progressively replaced by “well-differentiated (neuro)endocrine tumors/carcinomas”.

Synchronous primary lung cancer. Critical review of diagnostic criteria.

Question Of The Study: Synchronous primary lung cancers (SPLCs) may pose a radiologic-pathologic and therapeutic dilemma in according to recent WHO classification.

Patients And Methods: Two cases of surgically treated SPLCs are reported.

Results: In the first case two nodules were detected by Computed Tomography (CT) in the upper right lobe.

[Role of CT in the preoperative diagnosis of a giant benign solitary fibrous tumor of the pleura].

The authors emphasize the role of CT in the preoperative diagnosis of a giant benign solitary fibrous tumor of the pleura. CT can provide evidence of complete resection of the lesion, showing a pedunculated stalk. Aspiration cytology is not a reliable diagnostic approach.

[Small renal oncocytoma (≤ 4 cm): enhancement patterns on triphasic spiral computed tomography].

In 18 patients with 19 RO, 9 hypervascularity and hypovascularity was identified in 9 and 10 RO, respectively, in the cortico-medullary phase (CMP). Hypervascular RO showed increased density in the CMP (151.4±38.
