Mycobacterium tuberculosis of the meninges is the cardinal feature and the inflammation is concentrated towards the base of the brain. [6] When the inflammation is in the brain stem subarachnoid area, cranial nerve roots may be affected. The symptoms will mimic those of space-occupying lesions. [7]
There is a correlation between tuberculosis infections and cases of Pott's disease, as it's prevalent in areas where tuberculosis infections are common. Known risk factors like lower socioeconomic status, overcrowding, immunodeficiency, and interactions with people with tuberculosis can influence the rate of diagnosis.
A tuberculoma is a clinical manifestation of tuberculosis which conglomerates tubercles into a firm lump, and so can mimic cancer tumors of many types in medical imaging studies. [1] [2] They often arise within individuals in whom a primary tuberculosis infection is not well controlled. [3]
Tuberculosis (TB), also known colloquially as the "white death", or historically as consumption, [7] is a contagious disease usually caused by Mycobacterium tuberculosis (MTB) bacteria. [1] Tuberculosis generally affects the lungs , but it can also affect other parts of the body. [ 1 ]
Histopathological specimen showing tuberculosis of the duodenum. Lamina propria is stuffed with wall-to-wall histiocytes. This Kinyoun carbolfuchsin stain shows innumerable acid-fast bacilli. When it spreads to the bones, it is known as skeletal tuberculosis, [4] a form of osteomyelitis. [7] Tuberculosis has been present in humans since ancient ...
Mycobacteriology lab personnel; Persons with clinical conditions that place them at high risk (e.g., diabetes, prolonged corticosteroid therapy, leukemia, end-stage renal disease, chronic malabsorption syndromes, low body weight, etc.) Children less than 4 years of age, or children and adolescents exposed to adults in high-risk categories
Mycobacterium tuberculosis (M. tb), also known as Koch's bacillus, is a species of pathogenic bacteria in the family Mycobacteriaceae and the causative agent of tuberculosis. [ 1 ] [ 2 ] First discovered in 1882 by Robert Koch , M. tuberculosis has an unusual, waxy coating on its cell surface primarily due to the presence of mycolic acid .
Caseous necrosis in the kidney. In caseous necrosis no histological architecture is preserved (unlike with coagulative necrosis). [5] [6] On microscopic examination with H&E staining, the area is acellular, characterised by amorphous, roughly granular eosinophilic debris of now dead cells, [6] also containing interspearsed haematoxyphilic remnants of cell nucleus contents.
