Primary SARS-CoV-2 Pneumonia Screening in Adults: Analysis of the Correlation Between High-Resolution Computed Tomography Pulmonary Patterns and Initial Oxygen Saturation Levels.

Background: Chest High-Resolution Computed Tomography (HRCT) is mandatory for patients with confirmed Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection and a high Respiratory Rate (RR) because sublobar consolidation is the likely pathological pattern in addition to Ground Glass Opacities (GGOs).

Objective: The present study determined the correlation between the percentage extent of typical pulmonary lesions on HRCT, as a representation of severity, and the RR and peripheral oxygen saturation level (SpO), as measured through pulse oximetry, in patients with Reverse Transcriptase Polymerase Chain Reaction (RT-PCR)-confirmed primary (noncomplicated) SARS-CoV-2 pneumonia.

Methods: The present retrospective study was conducted in 332 adult patients who presented with dyspnea and hypoxemia and were admitted to Prince Mohammed bin Abdulaziz Hospital, Riyadh, Saudi Arabia between May 15, 2020 and December 15, 2020.

Brain MRI in SARS-CoV-2 pneumonia patients with newly developed neurological manifestations suggestive of brain involvement.

The increased frequency of neurological manifestations, including central nervous system (CNS) manifestations, in patients with coronavirus disease 2019 (COVID-19) pandemic is consistent with the virus's neurotropic nature. In most patients, brain magnetic resonance imaging (MRI) is a sensitive imaging modality in the diagnosis of viral encephalitides in the brain. The purpose of this study was to determine the frequency of brain lesion patterns on brain MRI in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pneumonia patients who developed focal and non-focal neurological manifestations.

Severe hypertension secondary to renal artery stenosis and Cushing's syndrome.

We present an unusual patient who simultaneously had severe renal artery stenosis RAS and Cushing's syndrome. The case highlights the difficulty of reaching a specific diagnosis of Cushing's syndrome and the possible interaction between Cushing's syndrome and some other concurrent illnesses that this patient had. A 37-year old man presented with severe hypertension HTN and uncontrolled diabetes mellitus DM without clear physical signs of Cushing's syndrome.

Large deep venous anomaly presenting as a left frontal lesion.

Venous angiomas` also known as deep vein anomalies (DVA), are one of the well-described brain vascular malformations. Frequently they are diagnosed as an incidental finding on neuroimaging (CT or MRI). A DVA may present as a single enhancing venous channel or as a large vascular abnormality illustrated on cerebral angiogram.

Neurobrucellosis: clinical and neuroimaging correlation.

Background And Purpose: Manifestation of nervous system involvement by neurobrucellosis, a treatable infection, is not well documented. We investigated patterns of nervous system involvement and determined if neuroimaging abnormalities correlated with clinical manifestations of neurobrucellosis.

Methods: We reviewed 23 MR imaging studies (17 of brain, six of spine) and seven CT scans of brain in 23 patients (14 male and nine female patients; age range 17-71 years) with positive Brucella titers in their serum and CSF.
