“…Pathophysiology.-Tenosynovitis caused by TB can occur from hematogenous spread. More frequently, it is an extension of tuberculous arthritis (47). Tenosynovitis progresses with the initial hygromatous stage, then the serofibrinous stage, and the fungoid stage is last.…”

Extrapulmonary Tuberculosis: Pathophysiology and Imaging Findings

2019

Extrapulmonary tuberculosis (TB) represents approximately 15% of all TB infections. It is difficult to diagnose on the basis of imaging characteristics and clinical symptoms, and biopsy is required in many cases. Radiologists must be aware of the imaging findings of extrapulmonary TB to identify the condition in high-risk patients, even in the absence of active pulmonary infection. In extrapulmonary TB, the lymphatic system is most frequently affected. The presence of necrotic lymph nodes and other organ-specific imaging features increases the diagnostic probability of extrapulmonary TB. Disseminated infection and central nervous system involvement are the most frequent manifestations in immunosuppressed patients. Renal disease can occur in immunocompetent patients with very long latency periods between the primary pulmonary infection and genitourinary involvement. In several cases, gastrointestinal, solid-organ, and peritoneal TB show nonspecific imaging findings. Tuberculous spondylitis is the most frequent musculoskeletal manifestation. It is usually diagnosed late and affects multiple vertebral segments with extensive paraspinal abscess. Articular disease is the second most frequent musculoskeletal manifestation, and synovitis is its predominant imaging finding. ©

“…1 Treatment is more likely to fail in cases of articular infection and osteomyelitis and can lead to persistent patient disability or even amputation. 7,12 Our patient presented with multiple risk factors for a poor prognosis despite his immunocompetency. His occupation as a farmer and his avian exposure predisposed him for infection by MAC, the most commonly identified species in bone and joint infections and known to be associated with treatment failure more than any other mycobacterial species.…”

Background: Nontuberculous mycobacteria are an uncommon pathogen for musculoskeletal infection and are difficult to treat because of delays in diagnosis, prolonged treatment requiring both antimycobacterial therapy and surgical debridement, and high rates of resistance to antimycobacterial therapy. Case Report: We report the case of an 88-year-old male with recurrent Mycobacterium avium complex tenosynovitis despite receiving multiple courses of pharmacologic therapy and surgical debridement. Conclusion: Nontuberculous mycobacterial musculoskeletal infections can be difficult to diagnose and equally difficult to treat. A combination of antimycobacterial therapy and surgical debridement is often required; however, the rate of treatment failure remains high, particularly with rapidly growing mycobacteria such as Mycobacterium avium.

“…In addition to the above signs, CT examination has the advantage of detecting lymphadenopathy, and serious complications such as vascular rupture, 51 assessing the extent of tissue or bone involvement, assisting in grading the extent of the disease, identifying a potential source of infection for debridement, [78][79][80] and also revealing nonspecific signs such as increase soft-tissue attenuation, subcutaneous edema, and inflammatory fat stranding. 58,81 Overall, CT is a reliable tool for the diagnosis of NF.…”

Necrotizing fasciitis is a clinical, surgical emergency characterized by an insidious onset, rapid progression, and a high mortality rate. The disease's mortality rate has remained high for many years, mainly because of its atypical clinical presentation, which prevents many cases from being diagnosed early and accurately, resulting in patients who may die from uncontrollable septic shock and multi‐organ failure. But unfortunately, no diagnostic indicator can provide a certain early diagnosis of NF, and clinical judgement of NF is still based on the results of various ancillary tests combined with the patient's medical history, clinical manifestations, and the physician's experience. This review provides a brief overview of the epidemiological features of NF and then discusses the most important laboratory indicators and scoring systems currently employed to diagnose NF. Finally, the latest progress of several imaging techniques in the early diagnosis of NF and their combined application with other diagnostic indices are highlighted. We point out promising research directions based on an objective evaluation of the advantages and shortcomings of different methods, which provide a basis for further improving the early diagnosis of NF.
