Torsion of the spermatic cord: the main gray-scale and doppler sonographic signs

Abdominal Imaging
Décio Prando

Abstract

Scrotal ultrasonography (US) is usually the initial imaging modality for evaluating patients who present with acute pathologic conditions of the scrotum. Acute epididymitis, acute epididymo-orchitis, torsion of the spermatic cord (TSC), and other acute scrotal abnormalities may have similar findings at clinical examination. Pain and swelling make the clinical examination difficult, sometimes practically impossible, potentially resulting in management delays. The objective of this review is to summarize the main clinical signs of the TSC and to illustrate and briefly discuss the US features of this entity, including gray-scale imaging, color Doppler with spectral analysis, and power Doppler sonography. Although TSC can occur at any age, it is most common in adolescent boys. The intensity of the symptoms and the US findings vary with the duration of the torsion, number of twists in the spermatic cord (degree of rotation), and how tightly the vessels of the cord are compressed. An enlarged, more spherical, and diffusely hypoechogenic testis without detectable arterial and venous testicular flow at color and power Doppler US is considered diagnostic of acute testicular ischemia. The presence of a color or power Doppler signal 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.
