Two cases of tuberculosis of the thoracic spine with extrapleural extension of paravertebral abscesses, presenting radiologically as cold abscesses away from the spine in the PA chest radiograph, are presented. The radiographic features and response to antitubercular drugs are discussed.
A retrospective review of 33 patients with tuberculosis of the spine from January 2000 to April 2002 revealed that the mean age was 36.5 and peak incidence is in the second decade of life (27.3%). There were 24 males and 9 females. The majority of the lesions involved the thoracic spine (30.3%), followed by the lumbar spine (27.2%). Skip lesions was seen in 12.1% of cases. The erythrocyte sedimentation rate was normal in 9.1% of patients. Neurological involvement was seen in 51.5% of patients. Concomitant tuberculosis of the lung was 66.6%. The radical surgical debridement and grafting rate was 39.3%. The preferred surgical procedure was that of radical anterior debridement and fusion supplemented by anterior or posterior instrumentation if needed. Anti-tuberculous chemotherapy remained the mainstay of treatment. Surgery gives faster relief of pain and neurological recovery but is a major undertaking, and thus selection of patients is vital to avoid morbidity and mortality.
Spinal tuberculosis is not common in the paediatric age group. Initial clinical features are often vague and non specific until the disease progresses to later stages. We highlight the diagnostic difficulties and management challenges of a complicated extradural tuberculoma with neurological deficits in a very young girl.
Instances of neurological recovery after early decompression of the spine in non-traumatic spinal cord compression are well documented. We present a patient with paraplegia of 11 months' duration due to atypical spinal tuberculosis who showed complete neurological recovery in three months.
This is a retrospective study of 53 patients with spinal tuberculosis treated in Sarawak General Hospital from 1994 until 1998. The study showed that the mean age in patients with spinal tuberculosis was 40.2 years, and was more common in male (70%) and in Iban population (50%). The clinical presentation included backache (94%); abscess (45%); neurological deficit (44%); and gibbus deformity (22%). The percentage of patient without BCG scar was 82% and 18% had evidence of pulmonary tuberculosis. The most common vertebra involved was the ninth thoracic vertebra and the least common was the third cervical vertebra. The average number of vertebra affected per patient was three. The most common radiological type of lesion was paradiscal (47%). The percentage of patients diagnosed by histological examination was 44%. All patients were given chemotherapy for 12 months' duration; 57% were treated surgically and 43% were treated conservatively. Twenty-four of patients (40%) had an excellent and good results and 28 of patients had a fair result and only one patient had poor result. In 23 of patients treated conservatively showed increment of 8 degrees of kyphosis angle and 22 of patients had a fair result and only one patient had poor outcome after 6 months of treatment. In 30 of patients treated surgically showed correction of 4 degrees of kyphosis angle and 24 of them had excellent and good outcome, where 6 of them had fair outcome after 6 months of treatment.
Various authors have reported differences in the radiological features of skeletal tuberculosis in the coloured patient. We studied retrospectively the radiographs of 71 patients with proven skeletal tuberculosis seen in our hospital, over a 6 year period. Sclerotic bone reactions and periosteal new bone formations were unusual findings but multiple bone involvement occurred about 15% of our patients. There was also a high in incidence of tuberculosis of the ankle and foot compared to that reported in white Caucasian patients.
Tuberculous paraplegia in pregnancy is reported to be rare. Paraplegia due to tuberculosis has a good prognosis if surgical decompression and stabilisation are done early together with chemotherapy. Vaginal delivery is not contraindicated in pregnancy complicated by paraplegia, but is associated with problems related to the initiation and progression of labour. Performing spinal nursing on an unstable spine with a rapidly enlarging gravid uterus in the third trimester of pregnancy poses a significant challenge. We report successful simultaneous Caesarean section and surgical treatment of a paraplegic spine due to tuberculosis.
Clinically, it is sometimes diffi cult to distinguish an infection of the spine from a metastasis. Spinal tuberculosis is common according to its endemic region and adenocarcinoma of the lung is also rising in the incidence worldwide. Similar presentations, with unknown primary, clinical fi ndings and hematological investigations rarely conclude a true diagnosis. Radiologically, the hallmark of spinal infection is erosion of adjacent vertebral endplates and narrowing of the disc space with or without a paravertebral shadow. Metastasis typically does not involve the disc space with erosion of the adjacent vertebral endplates. It usually presents as a lytic/sclerotic lesion in the vertebral body or “winkle owl” sign. These distinguishing features of infection versus metastasis are not certainties. Biopsy is mandatory whenever in doubt or patient is not responded with provisional treatment. The author presents a case with so-called radiological features of spinal tuberculosis infection, which turns out to be a metastatic adenocarcinoma of the lung.
In this study, we compared the platelet count with erythrocyte sedimentation rates (ESR) in patients with tuberculous spondylitis to evaluate the correlation. This was a retrospective 3-year study covering January 2004 to December 2006 at the Hospital Universiti Sains Malaysia. Platelet counts, hemoglobin levels, ESR, peripheral blood counts and peripheral blood smears on 17 patients with tuberculous spondylitis were obtained. The ages of the patients ranged from 20- to 70-years-old. The male to female ratio was 3.2:1. The majority of the patients were anemic (88.2%) and 52.9% of the patients had thrombocytosis. All the patients had normal lymphocyte counts and a high in ESR at diagnosis. There was a linear correlation between the platelet count and ESR (r = 0.60, p < 0.01). The platelet count was also significantly correlated with the hemoglobin level (r = -0.6, p < 0.02). The degree of thrombocytosis was related to the degree of inflammation measured by the ESR. Thrombocytosis also correlated with the hemoglobin level. We suggest that evaluating hematological values in suspected cases of tuberculosis should be considered. The presence of hematological changes should raise the suspicion of tuberculosis in spondylitis patients.
This study was conducted to determine the factors involved in predicting the onset of paraplegia in tuberculosis of the spine. A cross-sectional, case control review of 85 cases of spinal tuberculosis was conducted at the National Tuberculosis Centre in Kuala Lumpur. Sixty-nine of these cases were normal neurologically, whilst 16 cases experienced neural deficit. The data was analysed using backward logistic regression and Fishers exact probability test. The factors studied included symptoms and signs of spinal tuberculosis, common investigations for tuberculosis, and physical factors of the disease. Only the erythrocyte sedimentation rate (ESR) showed a significant difference between the neural deficit and neurologically normal groups. This suggests that the ESR may be a factor in predicting evolution of paraplegia in spinal tuberculosis. In addition, it was noted that a low proportion of patients had positive sputum smear results and bacterial culture growth for mycobacterium tuberculosis suggesting these tests are of limited value for tuberculosis of the spine.
Pedicle involvement in spinal tuberculosis (TB), the prevertebral abscess formation, severity of vertebral body, and disc collapse were evaluated from magnetic resonance imaging (MRI) of the patients.
Background: Tuberculous disease of spine (spinal TB) is under-recognized in tuberculous (TB) meningitis.
The objective of the study was to evaluate the frequency, clinical and neuroimaging changes, and
outcome in the patients with spinal TB.
Methods: All the patients with spinal TB admitted in the two
largest tertiary hospitals in Kuala Lumpur from 2009 to 2017 were recruited, the clinical features were
documented, the magnetic resonance imaging (MRI) of the spine was performed. Clinical outcome was
assessed with Modified Rankin scale (MRS).
Results: Twenty two patients were recruited. This was
out of 70 TB meningitis patients (31.4%) seen over the same period. Eighteen (81.8%) patients had
concomitant TB meningitis. The clinical features consisted of systemic symptoms with fever (63.6%),
meningitis symptoms with altered sensorium (45.5%), myelopathy with paraparesis (36.4%). The
findings on spinal MRI were discitis (36.4%), spinal meningeal enhancement (31.8%), spinal cord
compression (31.8%), psoas abscess (27.3%), osteomyelitis (22.7%), and cord oedema (22.7%). All
except two patients (90.9%) had involvement in psoas muscle, bone or leptomeningeal enhancement,
features that can be used to differentiate from myelopathy that affect the parenchyma only, such as
demyelination. Unusual manifestations were syringomyelia and paradoxical manifestations seen in 3
patients each. The outcome were overall poor, with 68% having MRS 3 or more.
Conclusion: Spinal TB is common in TB meningitis. The outcome is overall poor. A heightened
awareness is crucial to enable early diagnosis and treatment.
Two hundred and nineteen patients with skeletal tuberculosis have been reviewed analysing the site of the lesion and the treatment given. Operative management is advocated since the results of this approach are encouraging.
Extraintestinal Salmonella infection involving the thoracic spine is very rare. It commonly presents with non-specific chronic back pain and can occur with no gastrointestinal manifestation. Blood test results and imaging findings are often indistinguishable from more common chronic spine infections such as spine tuberculosis. Culture studies remain the key to establishing a definitive diagnosis and subsequently successful treatment. We report a case in which a patient presented with symptoms and signs suggestive of spine tuberculosis, yet the culture examination revealed otherwise.
Tuberculosis can cause extensive osseo-ligamentous destruction at the cranio-vertebral junction, leading to atlanto-axial instability and compression of vital cervico-medullary centres. This may manifest as quadriparesis, bulbar dysfunction and respiratory insufficiency.
One hundred and forty-one patients with non-traumatic paraplegia were reviewed. The common causative factors and the problems arising were evaluated. Management of the clinical problems were described. The need for prevention and early treatment has been stressed.
The most effective treatment for spinal tuberculosis was by eliminating the tuberculosis bacteria and replacing the infected bone with the bone graft to induce the healing process. This study aims to synthesize and characterize nanohydroxyapatite-gelatin-based injectable bone substitute (IBS) with addition of streptomycin. The IBS was synthesized by mixing nanohydroxyapatite and 20 w/v% gelatin with ratio of 40:60, 45:55, 50:50, 55:45, 60:40, 65:35, 70:30, and 75:25 ratio and streptomycin addition as antibiotic agent. The mixture was added by hydroxypropyl methylcellulose as suspending agent. FTIR test showed that there was a chemical reaction occurring in the mixture, between the gelatin and streptomycin. The result of injectability test showed that the highest injectability of the IBS sample was 98.64% with the setting time between 30 minutes and four hours after injection on the HA scaffold that represents the bone cavity and coat the pore scaffold. The cytotoxicity test result showed that the IBS samples were nontoxic towards BHK-21 fibroblast cells and human hepatocyte cells since the viability cell was more than 50% with significant difference (p-value<0.05). The acidity of the IBS was stable and it was sensitive towards Staphylococcus aureus with significantly difference (p-value<0.05). The streptomycin release test showed that the streptomycin could be released from the IBS-injected bone scaffold with release of 2.5% after 4 hours. All the results mentioned showed that IBS was suitable as a candidate to be used in spinal tuberculosis case.
