Brain abscess (or cerebral abscess) is an abscess within the brain tissue caused by inflammation and collection of infected material coming from local (ear infection, dental abscess, infection of paranasal sinuses, infection of the mastoid air cells of the temporal bone, epidural abscess) or remote (lung, heart, kidney etc.) infectious sources.
MRI scans produce more detailed images of bodily structures, particularly soft tissues including the brain, [13] and are better at detecting CNS metastases than CT scans. However, CT scans are sometimes used for the initial imaging modality due to their lower cost and efficiency in screening for multiple conditions.
A brain metastasis is a cancer that has metastasized (spread) to the brain from another location in the body and is therefore considered a secondary brain tumor. [ 1 ] [ 2 ] The metastasis typically shares a cancer cell type with the original site of the cancer. [ 3 ]
Andrew’s machine learning model uses a block-based 3D U-Net architecture to make brain metastasis segmentation more precise, achieving higher Dice scores than current methods. This improvement allows for more precise delineation of tumor margins, making it easier to distinguish cancerous tissue from surrounding healthy brain structures.
In Nevada last year, the number of brain abscesses in kids tripled — rising from an average of four to five a year to 18

Amoebic brain abscess is an affliction caused by the anaerobic parasitic protist Entamoeba histolytica.It is extremely rare; the first case being reported in 1849. [2] Brain abscesses resulting from Entamoeba histolytica are difficult to diagnose and very few case reports suggest complete recovery even after the administration of appropriate treatment regimen.
