Intracranial neurenteric cysts are rare congenital lesions that can be mistaken for other lesions. They may contain mucous or serous glands, smooth muscle, lymphoid tissue and components of connective tissue. We report a case of neurenteric cyst which was detected accidentally by diagnostic imaging in the context of a thalamus infarct in a 45-year-old woman. We also discuss the results of a brief literature review and the pathological findings, imaging spectrum, evaluation and management of neurenteric cysts and thalamic infarctions.

The features of the structure of the esophagus and its lymphoid tissue of the house sparrow (Passer domesticus) have been studied. It is shown that its wall is formed by well expressed mucous, muscular and least developed adventitial (serous in the caudal part) shells. The mucosa forms 7–9 longitudinal folds of leaf-shaped and finger-shaped forms directed into the lumen of the esophagus. It consists of epithelium, lamina propria, lamina muscularis and submucosa. The epithelial layer is represented by a multi-layered flat, weakly keratinizing epithelium and is better developed in the cranial part of this organ. Near the proventriculus, it passes into a single-layered cylindrical. In its lamina propria of the mucosa there are bags of numerous large esophageal glands in which mucus is recorded. Their excretory ducts open onto the surface of the mucosal epithelium. The lamina muscularis is intermittent in places, formed by a smooth muscle tissue. The submucosa is weakly expressed and its own plate is formed by a loose fibrous connective tissue with blood vessels. Between the esophagus glands, their excretory ducts and in the submucosa of the tunica mucosa on the border with the tunica muscular are separate clusters of diffuse lymphoid tissue, which are represented by cells of the lymphoid series without noticeable rarefaction and densities. The basis of the diffuse lymphoid tissue is the reticular tissue, the fibers of which, are densely disposed and do not have a definite orientation and form a small grid. In the area of transition of the esophagus to the proventriculus, the esophageal tonsil, which is inherent in many species of birds, is not expressed. In this area in the mucous membrane, only local accumulations of diffuse lymphoid tissue are recorded. There are no prenodules and lymphoid nodules. The tunica muscular of the esophagus is formed by a smooth muscle tissue, which forms the inner–circular and outer – longitudinal layers. Between them, layers of loose fibrous connective tissue and blood vessels are identified. Tunica adventitia (serosa) are formed by a loose fibrous connective tissue, and serosa is also covered by mesothelium.

Work Up

Diagnostic imaging is regarded as fundamental in the clinical work-up of patients with a suspected or confirmed COVID-19 infection. Recent progress has been made in diagnostic imaging with the integration of artificial intelligence (AI) and machine learning (ML) algorisms leading to an increase in the accuracy of exam interpretation and to the extraction of prognostic information useful in the decision-making process. Considering the ever expanding imaging data generated amid this pandemic, COVID-19 has catalyzed the rapid expansion in the application of AI to combat disease. In this context, many recent studies have explored the role of AI in each of the presumed applications for COVID-19 infection chest imaging, suggesting that implementing AI applications for chest imaging can be a great asset for fast and precise disease screening, identification and characterization. However, various biases should be overcome in the development of further ML-based algorithms to give them sufficient robustness and reproducibility for their integration into clinical practice. As a result, in this literature review, we will focus on the application of AI in chest imaging, in particular, deep learning, radiomics and advanced imaging as quantitative CT.

AbstractLipomas are common benign connective tissue tumours composed of adult adipose tissue. They are relatively rare in the upper aerodigestive tract, although they occur with considerable frequency in other areas, particularly in the subcutaneous tissues of the neck. Although there are several reports of this tumour occurring in the oropharynx, there is no recorded case of a lipoma of the tonsillar fossa. An 83-year-old man with a left tonsillar fossa lipoma is presented. Clinical presentation, management and a literature review are discussed.

Endothelial Growth Factor

Airway remodeling describes the structural changes that occur in the asthmatic airway that include airway smooth muscle hyperplasia, increases in vascularity due to angiogenesis, and thickening of the basement membrane. Our aim in this study was to examine the effect of transforming growth factor-β on the release of connective tissue growth factor and vascular endothelial growth factor from human airway smooth muscle cells derived from asthmatic and nonasthmatic patients. In addition we studied the immunohistochemical localization of these cytokines in the extracellular matrix after stimulating bronchial rings with transforming growth factor-β. Connective tissue growth factor and vascular endothelial growth factor were released from both cell types and colocalized in the surrounding extracellular matrix. Prostaglandin E2 inhibited the increase in connective tissue growth factor mRNA but augmented the release of vascular endothelial growth factor. Matrix metalloproteinase-2 decreased the amount of connective tissue growth factor and vascular endothelial growth factor, but not fibronectin deposited in the extracellular matrix. This report provides the first evidence that connective tissue growth factor may anchor vascular endothelial growth factor to the extracellular matrix and that this deposition is decreased by matrix metalloproteinase-2 and prostaglandin E2. This relationship has the potential to contribute to the changes that constitute airway remodeling, therefore providing a novel focus for therapeutic intervention in asthma.
