Localised giant pseudopolyposis secondary to ulcerative or granulomatous colitis

Clinical Radiology
N Joffe


Pseudopolyps which represent polypoid oedematous tags, regenerating mucosal islands between ulcerations or heaped-up granulation tissue covered by epithelium, are a common sequela of ulcerative colitis and may also occur secondary to granulomatous colitis. Occasionally, a large discrete mass of pseudopolyps occurs simulating a villous-like or polypoid neoplasm and the term 'localised giant pseudopolyposis' has been applied to this phenomenon. In this paper the radiological appearances of localised giant pseudopolyposis secondary to ulcerative or granulomatous colitis are described and illustrated. The differential diagnosis is discussed and four new cases are added to eight previously reported in the literature.

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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Pediculosis pubis

Pediculosis pubis is a disease caused by a parasitic insect known as Pthirus pubis, which infests human pubic hair, as well as other areas with hair including eye lashes. Here is the latest research.

Rh isoimmunization is a potentially preventable condition that occasionally is associated with significant perinatal morbidity or mortality. Discover the latest research on Rh Isoimmunization here.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
