Aim: To correlate selected clinical and ultrasonographic (US) characteristics with the final histopathological diagnosis in patients with atypia of undetermined significance (AUS) and follicular lesion of undetermined significance (FLUS), and whether this information can be used in planning the surgical approach.
Materials and methods:It is a retrospective study including the operated cases of AUS/FLUS from 2011 to 2014 treated at one center.Results: This cohort included 87 women and 28 men. To test for independence between categorical variables, the chi-square test was used. There was no significant correlation between age or US variables and final pathological diagnosis. However, final diagnosis of malignancy was higher in men compared with women (64.3 and 41.4% respectively; p = 0.035). Furthermore, a significant association between the diagnosis of repeated fine needle aspiration biopsy (FNAB) and the final pathological diagnosis was noted (benign vs malignant, p = 0.005).
Conclusion:The FNAB has a significant role in the assessment of thyroid nodules. Our results showed no correlation between age, US variables, and the risk of malignancy. Male gender is associated with higher risk of malignancy.Clinical significance: Determining the risk of malignancy and prediction of surgical outcome may help triaging cases for repeat FNA or proceeding to surgery.
Primary CNS vasculitis is an inflammatory brain disease commonly misdiagnosed affecting the medium and small vessels of the CNS. Due to its broad and non-specific clinical and radiological manifestations; Its diagnosis remains challenging. New diagnostic tools and biomarkers which increase specificity and facilitate the diagnosis for patients with suspected vasculitis are highly desirable to enable physicians to start therapy that can alter its potential aggressive course like immunosuppressant.
This case report highlights the potential role of
18
F-choline PET/MRI as a novel imaging tool that might help in the right clinical scenario in the diagnosis of this disease.
Furthermore, it speculates on its secondary role in monitoring the response to immunosuppressant therapy.
Typhlitis (neutropenicenterocolitis) is a life-threatening condition with 50% mortality occurring in 3.5% of adult neutropenic patients. With no definitive physical findings, diagnosis is usually made with contrast-enhanced computerised tomography (CECT). We present the first-ever case of this diagnosis being made with 18F-FDG PET/CT.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
