Progress
- Tuberculoma
- Single or multiple lesions of > 0.5 cm
- May occur in primary or secundary TB
- Main finding on Chest X-ray in 5% cases of secondary TB[1]
- Results from the surrounding of M. tuberculosis with inflammatory or connective tissue.[2][3][1]
- The center of the tuberculoma is often necrotic
- Satellite lesions (80%)
- Nodular or diffused calcifications in 20-30% cases[2]
- Thin-walled cavity
- Present in active and inactive disease
- May regress after treatment
- Air-filled sect may persist[4]
- May be misidentified as an emphysematous bulla or pneumatocelle.
- Cicatrization:
- Drug Destruction:
Differential Diagnosis of Infectious Diarrhea
Acute inflammatory diarrhea may be caused by different pathogens. Bellow is a table describing some of these pathogens in terms of transmission and symptoms:[5][6]
| Pathogen | Transmission | Clinical Manifestations | |||
|---|---|---|---|---|---|
| Fever | Nausea/Vomiting | Abdominal Pain | Bloody Stool | ||
| Salmonella | Foodborne transmission, community-acquired | ++ | + | ++ | + |
| Shigella | Community-acquired, person-to-person | ++ | ++ | ++ | + |
| Campylobacter | Community-acquired, ingestion of undercooked poultry | ++ | + | ++ | + |
| E. coli (EHEC or EIEC) | Foodborne transmission, ingestion of undercooked hamburger meat | ± | + | ++ | ++ |
| Clostridium difficile | Nosocomial spread, antibiotic use | + | ± | + | + |
| Yersinia | Community-aquired, foodborne transmission | ++ | + | ++ | + |
| Entamoeba histolytica | Travel to or emigration from tropical regions | + | ± | + | ± |
| Aeromonas | Ingestion of contaminated water | ++ | + | ++ | + |
| Plesiomonas | Ingestion of contaminated water or undercooked shellfish, travel to tropical regions | ± | ++ | + | + |
