Tuberculous peritonitis (TP) is identified by ascites with high protein content, a low glucose and low SAAG, elevated ascitic fluid WBC count, and lymphocyte predominance.
What are radiological findings of TB?
Common findings include segmental or lobar airspace consolidation, ipsilateral hilar and mediastinal lymphadenopathy, and/or pleural effusion. Atelectasis may occur in primary pulmonary tuberculosis, often as a consequence of tuberculous airway involvement.
What causes tuberculous peritonitis?
Tuberculous peritonitis usually results from tuberculosis of the gastrointestinal tract. It is believed to be due to hematogenous spread, but can occur with perforation of bowel, lymph nodes, or fallopian tubes.
How does TB appear on CT scan?
Typical CT findings of reactivation of pulmonary TB include centrilobular small nodules, branching linear opacities, patchy consolidation, and cavitation (19–21). Post-primary TB most commonly involves the upper lobes and the superior segments of the lower lobes (25, 26).
Is tuberculous peritonitis curable?
Conclusions: TB peritonitis may be fatal but is medically cured if diagnosed in a timely fashion. It is essential that the clinician suspect the disease in appropriate patients. Tests frequently associated with TB such as chest radiograph and purified protein derivative are not sensitive in detection of TB peritonitis.
What is primary TB?
Primary TB is defined as infection occurring in previously uninfected host ○ Primary infection is usually asymptomatic and leads to formation of Ghon complex (apical nodule with calcification) and hilar lymphadenopathy.
Is TB peritonitis infectious?
Tuberculous peritonitis (TBP) is primarily caused by hematogenous spread and rarely results from the contagious spread of an infected bowel or fallopian tubes (1,2).
Can a CT scan confirm TB?
The early diagnosis of tuberculosis (TB) is mandatory for effective treatment and control. Chest radiography is essential in the diagnosis of primary pulmonary TB. Computed tomography (CT) is the preferred imaging modality for lymphadenopathy, bronchogenic spread, and abdominal TB.
Is TB peritonitis contagious?
How do you treat abdominal TB?
Abdominal TB needs to be treated with at least 3-4 anti TB drugs for the initial 2 months and subsequently 2 anti TB drugs for at least 7-10 months. The commonly used drugs during the initial 2 months therapy (intensification phase) are Isoniazid (INH), Rifampicin, Ethambutol and Pyrazinamide.
What are the radiographic features of pulmonary tuberculosis (TB)?
Radiographic features. Primary pulmonary tuberculosis manifests as four main entities: parenchymal disease usually manifests as dense, homogeneous parenchymal consolidation in any lobe. however, predominance in the lower and middle lobes (subpleural sites) is suggestive of the disease, especially in adults 1. lymphadenopathy. miliary opacities.
What is the pathogenesis of tuberculosis?
Tuberculosis encompasses an enormously wide disease spectrum affecting multiple organs and body systems predominantly caused by the organism Mycobacterium tuberculosis. A small proportion can also be caused Mycobacterium bovis.
What is the prevalence of tuberculoma in tuberculosis (TB)?
Tuberculomas account for only 5% of cases of post-primary TB and appear as a well defined rounded mass typically located in the upper lobes. They are usually single (80%) and can measure up to 4 cm in size. Small satellite lesions are seen in most cases 1. In 20-30% of cases, superimposed cavitation may develop.
What is the natural history of tuberculosis (TB)?
The natural history of tuberculosis is complex. Primary infection, the initial phase, occurs in people without specific immunity, generally normal children and young adults who have not previously been exposed to Mycobacterium tuberculosis. The initial infection can occur at any time during childhood, but adolescence is the peak time of risk.
