Accessory cavitated uterine mass: MRI features and surgical correlations of a rare but under-recognised entity

European Radiology

Abstract

To describe MRI features of accessory cavitated uterine mass (ACUM) with surgical correlations. Eleven young women with an ACUM at pathology underwent preoperative pelvic MRI. Two experienced radiologists retrospectively analysed MR images in consensus to determine the lesion location within the uterus, its size, morphology (shape and boundaries), and structure reporting the signal and enhancement of its different parts compared to myometrium. The presence of an associated urogenital malformation or other gynaecological anomaly was reported. MRI features were correlated with surgical findings. All 11 lesions were well correlated with surgical findings, lateralised (seven were left-sided), and located under the horn and the round ligament insertion. Nine were located within the external myometrium, bulging into the broad ligament. Two were extrauterine, entirely located within the broad ligament. On MRI, the mean size was 28 mm (range 17-60 mm). Nine lesions were round-shaped, two were oval; all had regular boundaries. At surgery, the ACUM were not encapsulated but were possible to enucleate. On MRI, all lesions were well defined and showed a central haemorrhagic cavity surrounded by a regular ring (mean thickness, 5 mm) which h...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.
