The Role of Folate Deficiency as a Potential Risk Factor for Nontraumatic Anterior Spinal Artery Syndrome in an Adolescent Girl.

Nontraumatic anterior spinal artery syndrome (ASAS) is an extremely rare clinical condition in pediatric populations with a mostly unknown underlying etiology. Here we discuss the case of a previously healthy 14-year-old girl presenting with sudden onset acute flaccid paralysis to the emergency department. A spinal STIR/DWI MRI revealed hyperintensities extending from cervical vertebrae C3-6, consistent with the diagnosis of ASAS.

Case report: Vaccine-induced immune thrombotic thrombocytopenia complicated by acute cerebral venous thrombosis and hemorrhage after AstraZeneca vaccines followed by Moderna COVID-19 vaccine booster and surgery.

Vaccine-induced thrombotic thrombocytopenia (VITT) is a well-known complication of adenoviral vector COVID-19 vaccines including ChAdOx1 nCoV-19 (AstraZeneca) and Ad26. COV2.S (Janssen, Johnson & Johnson).

Steroid-Responsive Gradenigo's Syndrome Mimicking Subdural Hematoma.

Gradenigo's syndrome (GS) is featured by a clinical triad of otorrhea, retro-orbital pain, and a sixth nerve palsy. Clinical examination is crucial prior to considering neuroimaging. The majority of cases are secondary to infection thus requiring long-term broad-spectrum antibiotics; severe cases also require surgical intervention for risk of intracranial abscess or even death.

Whole Exome Sequencing Identifies a Novel Homozygous Missense Mutation in the CSB Protein-Encoding Gene in a Taiwanese Boy with Cockayne Syndrome.

Background: Cockayne syndrome (CS) is a rare form of dwarfism that is characterized by progressive premature aging. CS is typically caused by mutations in the excision repair cross-complementing protein group 6 () gene that encodes the CS group B (CSB) protein. Using whole exome sequencing, we recently identified a novel homozygous missense mutation (Leu536Trp) in CSB in a Taiwanese boy with CS.

Differentiation of Malignant and Benign Incidental Breast Lesions Detected by Chest Multidetector-Row Computed Tomography: Added Value of Quantitative Enhancement Analysis.

To retrospectively determine the association between breast lesion morphology and malignancy and to determine the optimal value of lesion enhancement (HU, Hounsfield units) to improve the diagnostic accuracy of breast cancer in patients with incidental breast lesions (IBLs). A total of 97 patients with 102 IBLs detected from July 2009 to December 2012 were enrolled in this study. Two radiologists analyzed CT images for the presence of malignancy based on the morphology of the lesions alone and in combination with an enhancement value (HU) analysis.

Breast Nonmass Enhancement Detected with MRI: Uility and Lesion Characterization with Second-Look Ultrasonography.

The purpose of this study was to verify the utility of second-look ultrasonography (US) in evaluating nonmass enhancement (NME) lesions detected on breast magnetic resonance imaging (MRI) by analysing its correlation and imaging features. From July 2008 to June 2012, 102 consecutive MRI-detected NME lesions were subsequently evaluated with US. Lesions were evaluated according to the established Breast Imaging Reporting and Data System (BI-RADS) lexicon.

Non-mass-like breast lesions at ultrasonography: feature analysis and BI-RADS assessment.

Objective: To analyze the features of non-mass-like (NML) breast lesions on ultrasound (US) and determine their corresponding malignancy rate and to stratify these lesion patterns according to US BI-RADS categories.

Materials And Methods: One hundred sixty-four consecutive lesions were retrospectively classified into four types according to the US features, the corresponding positive predictive values (PPVs) were obtained. Clinical, imaging, and histopathological findings were reviewed.
