Abstract

Thoracic ganglioneuroma is sporadic and rarely reported. Pre-operative misdiagnosis often occurs in clinical practice. To improve diagnostic accuracy and facilitate differential diagnosis, we summarised the CT and MRI findings of thoracic ganglioneuroma. 22 cases of thoracic ganglioneuroma confirmed by surgery and pathology were retrospectively analysed in terms of CT (16 cases) and MRI data (6 cases). Of 22 lesions, 19 occurred in the posterior mediastinum, 2 in the lateral pleura and 1 in the right chest. The CT value of the plain scans ranged from 20 to 40 HU (mean 29.1 HU) in 16 cases. Punctate calcification was noted in four cases. Patchy fat density shadow was found in one case. Arterial-phase CT found nearly no enhancement (6 cases) or slight enhancement (10 cases) with a CT value of 0-12 HU (mean 5.8 HU). In the delayed phase, enhancement was strengthened progressively, and CT value of 10-20 HU (mean 13.6 HU) was achieved after 120 s. T(1) weighted images showed homogeneous hypointense signals in five cases and hypointense signals mixed with patchy hyperintense signal shadow in one case. T(2) weighted images demonstrated heterogeneous hyperintense signals in all six cases, of which the whorled appearance was noted in on...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
