Classic findings of … The musculoskeletal system is the most common extrapulmonary site of TB infection, with spinal involvement seen in 50% of skeletal cases. 2. Author information: (1)Department of Radiology, University of Southern California School of Medicine, LAC-USC Medical Center 90033. Involvement of the posterior elements is rare ( Fig. Among these, tuberculous infection of the spine is the most common. Rajendra Kumar4, Sowmya Jagadish5, Pradeep Hagalahalli Nagarajegowda6, Ashwin Raghavendra7 1 Resident, 2Assistant Professor, 3Professor, … TB can also affect the meninges of the spine, causing an intense pachymeningitis that enhances dramatically. Link, Google Scholar There is usually a slow collapse of one or usually more vertebral bodies, which spreads underneath the longitudinal ligaments. Spread of infection can occur beneath the longitudinal ligaments involving the adjacent vertebral bodies. Burrill J, Williams CJ, Bain G et-al. Spinal TB may be osseous or nonosseous. Unfortunately, the incidence of tuberculous spondylitis, as with other forms of TB, is on the rise, due to new multiple drug resistant strains. It accounts for approximately half of all cases of musculoskeletal tuberculosis. 1. Extrapulmonary tuberculosis (TB) is uncommon but not rare. Notably, TB is notoriously difficult to isolate on cultures, averaging 4 to 6 weeks to obtain results, with a sensitivity of 80%. Tuberculosis of the spine: imaging features. Due to the subligamentous extension, there may be some irregularity of the anterior vertebral margin. Initial vertebral body involvement may be indistinguishable from early pyogenic spondylitis; however, the disc space is uniquely spared in the early and intermediate phases of tuberculous spondylitis, in contrast to pyogenic bacterial infections. Furthermore, the classic constitutional symptoms of TB (e.g., fever, night sweats, weight loss) are present in less than 40% of spinal cases and may not become clinically apparent for months after initial spinal involvement. 1 As a result, the radiographic findings and the signs and symptoms are typically far advanced when the diagnosis is finally established. Spinal tuberculosis: atypical observation at MR imaging. DR HARDIK PAWARTUBERCULOSIS OFSPINE“Yakshma” 2. common in INDIA 1-3% -osseous involvement >50% affects spinal column - commonest form of skeletal TB. Imaging in children with spinal tuberculosis: a comparison of radiography, computed tomography and magnetic resonance imaging. As a result, the clinical diagnosis of early spinal TB can be difficult in patients without a known history of pulmonary TB. 20 (2): 449-70. After the vertebral body is involved, the infection will spread along the undersurface of the longitudinal ligaments to involve multiple adjacent vertebrae and into the epidural/paraspinal soft tissues to form abscesses. The usual duration of illness ranges from 4 to 11 months. Pott disease, also known as tuberculous spondylitis, is one of the oldest demonstrated diseases of humankind, having been documented in spinal remains from the Iron Age in Europe and in ancient mummies from Egypt and the Pacific coast of South America. TB infection is spread hematogenously either arterially or by Batson venous plexus, with the primary exposure site occurring in the lungs or genitourinary system. Classic findings of multiple contiguous vertebral body involvement, gibbus formation, and subligamentous spread with paravertebral … C44 International ournal o Conteorar Medicine Surger and Radiology Volume 3 Issue 3 July-September 2018 MRI Evaluation of Tuberculosis of Spine Rashmi U. Turamari1, Pradeep Kumar Chandandur Nagarajaiah2, Chakenalli Puttaraju Nanjaraj3, N.L. Acid-fast staining or polymerase chain reaction can be used to quickly identify the organism when specifically suspected. Tuberculosis of spine 1. 1995 Mar;164(3):659-64. Lastly, spinal TB is far from a new disease. Cross-sectional imaging is required to assess better the extent of involvement and particularly for the presence of an epidural component and cord compression. Less than half of these patients will have simultaneous pulmonary infection. Unlike pyogenic infections, the discs can be preserved and it more commonly involves the thoracic spine. This is a classical appearance with TB spondylitis. PURPOSE: To evaluate atypical magnetic resonance (MR) imaging features of spinal tuberculosis. A reduction in vertebral height is often seen with the irregularity of the anterosuperior end plate being relatively early and subtle sign. Tuberculosis (TB) is classically considered an infectious disease of developing countries; however, it has made a resurgence in other areas of the world with the increased use of immunosuppressive drugs, increased immigration, and the relatively recent appearance of HIV. DIFFERENCES OF MRI FEATURES BETWEEN TUBERCULOUS AND BACTERIAL SPONDYLITIS IN A TB-ENDEMIC AREA. Radiologic examinations are one of the first and most important steps in establishing the diagnosis of tuberculous spondylitis. Spinal tuberculosis is … We report a case of a 39-year-old woman presenting with vague back swelling for many years. 10.1055/b-0038-162845 8 Spinal Tuberculosis: Pathogenesis, Clinical Features, and InvestigationsRishi M. Kanna, Ajoy Prasad Shetty, and S. Rajasekaran Introduction Chronic infections of the vertebral column are usually granulomatous and are caused by mycobacteria, fungi, and Brucella species. Spinal tuberculosis (Pott disease) is not an uncommon manifestation. The spine is the most frequent location of musculoskeletal tuberculosis, and commonly related symptoms are back pain and lower limb weakness/paraplegia. Disc destruction is typically not present in tuberculous spondylitis, which is thought to be due TB’s lack of proteolytic enzymes, which are present in most pyogenic bacterial infections. 5. Histopathology of the bone biopsy may show nonspecific granulomatous changes suggesting TB. Within endemic countries, tuberculous spondylitis typically affects children and young adults during primary lung infection; however, in Western countries adults are more commonly affected after reactivation of latent disease. Objectives: A review of literature on the epidemiology, diagnosis, and management of spinal tuberculosis (TB). It causes a kind of tuberculous arthritis of the intervertebral joints. (A and B) Axial CT scan shows destruction of laminae and spinous process. However, the smallest annual decrease in the past 10 years occurred in 2003, with the reported prevalence of tuberculosis actually rising in some states and in certain populations (,1). Between 1990 and 1993, five of 11 consecutive patients with spinal tuberculosis (two men and three women, aged 30-57 years) had MR findings more suggestive of neoplasm than infection. Thammaroj J, Thammaroj KA, Thammaroj SK, Thammaroj. Radiographics. 3. In late-stage spinal TB, large paraspinal abscesses without severe pain or frank pus are common, leading to the expression "cold abscess". Harisinghani MG, Mcloud TC, Shepard JA et-al. The lower thoracic and upper lumbar vertebrae areas of the spine are most often affected.. Check for errors and try again. In spinal tuberculosis, the superior contrast resolution of MR imaging is useful for showing contiguous vertebral involvement, skip lesions, and paraspinal collections. This results in an acute kyphotic or "gibbus" deformity. Spinal tuberculosis and tuberculous psoas abscess. By Dr Shahid LatheefDepartment of OrthopaedicsYenepoya Medical CollegeMangalore 2. spinal cord injury can be caused by abscess/bony sequestra or meningomyelitis; abscess/bony sequestra has a better prognosis than meningomyelitis as the cause of spinal cord injury; Atypical Spinal Tuberculosis: definition compressive myelopathy without visible spinal deformity, without typical radiological appearance Radiographics. (2007) ISBN:0781765188. The radiologic infections of the spine and their diagnostic value. Shanley DJ(1). Acute Nontraumatic Back Pain: Infections and Mimics. ADVERTISEMENT: Supporters see fewers/no ads. Neurologic complaints are much more common at this stage of the disease because the kyphosis can result in compression of the anterior spinal cord. The goal of early diagnosis is avoiding significant morbidity associated with spinal instability, which may occur with delayed treatment. Ahmadi J(1), Bajaj A, Destian S, Segall HD, Zee CS. This angulation, coupled with epidural granulation tissue and bony fragments, can lead to cord compression. Radiology. It manifests secondary to extension through hematogenous route. Medline, Google Scholar; 52 Modic MT, Feiglin DH, Piraino DW, et al. This increase has been seen not only in Africa and Asia, bu… DNA analysis has identified TB strains from bone biopsies of ancient Egyptian mummies, making it one of the oldest known communicable diseases. Tuberculous spondylitis refers to vertebral body involvement with TB. Allen EH, Cosgrove D, Millard FJC. ABSTRACT : Spinal tuberculosis, the most common form of skeletal involvement, is increasing in prevalence because of the resurgence of tuberculosis during the past decade in patients with AIDS, the spread of tuberculosis among the homeless, and the expanding immigrant population. 6. Radiology (X-rays) is used in the diagnosis of tuberculosis.Abnormalities on chest radiographs may be suggestive of, but are never diagnostic of TB, but can be used to rule out pulmonary TB. Classically, spinal tuberculosis is thought to begin in the anteriorjinferior portion of the vertebral body [6, 7]. Lippincott Williams & Wilkins. However, newer multidrug resistant TB strains have been discovered, necessitating prolonged and aggressive treatment regimens. Unable to process the form. Pott disease is tuberculosis of the spine, usually due to haematogenous spread from other sites, often the lungs. Spinal tuberculosis: atypical observations at MR imaging. After suspicious imaging abnormalities are identified in the spine, percutaneous image-guided bone or soft tissue biopsies can be performed. Spinal infection-tuberculosis. respond well to simple decompres- tension. 27 (5): 1255-73. The spine is involved due to hematogenous spread via the venous plexus of Batson 2. 27.1 ). When compared with pyogenic infections of the spine, tuberculous spondylitis has a distinct pattern of spinal involvement on imaging, as well as a unique pattern of progression that warrants its own description. MRI is the modality of choice for this, with CT with contrast being a distant second. Tuberculous spondylitis is one of the more common infections of spine in countries where TB is prevalent. Most patients will seek medical care only after developing severe pain or neurologic complications. Spinal infection-tuberculosis. Patients usually present with back pain, lower limb weakness/paraplegia, and kyphotic deformity. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. J Spinal Disord Tech. Spinal tuberculosis or Pott's disease is an infection of the vertebral column caused by Mycobacterium tuberculosis. (2019) Radiographics : a review publication of the Radiological Society of North America, Inc. 39 (1): 287-288. • The primary problems today are : The delay in diagnosis (average 3months) The long recovery period (average 12months) The great cost of treating such infections. Tuberculous spinal infections are most often encountered in the lower thoracic or upper lumbar spine, although any spinal segment may be involved. (2015) The Southeast Asian journal of tropical medicine and public health. In some instances the diagnosis may be delayed by more than a year. Spinal tuberculosis accounts for around 2% of all cases of tuberculosis and around 15% of extrapulmonary tuberculosis cases . tuberculosis of spine 1. Both modalities are useful 15. Anatomically, the thoracic spine is the most commonly affected site followed by the lumbar and cervical vertebrae in turn. MR imaging provides critical information about the spinal cord and the extent of the epidural pus in patients presenting with neurologic deficits.
