Posterior spinal cord compression: outcome and results.
ABSTRACT Prospective, comparative study of neurologic outcome in patients with posterior extradural cord compression.
To compare the results of surgical decompression in patients presenting with neurologic deficit due to posterior element tuberculosis with those due to other causes.
Posterior cord compression is a relatively uncommon entity with not much literature published on it.
Over a period of 5 years, 14 patients with extradural posterior cord compression with neurologic deficit were divided into two etiologic groups: 9 patients had Koch's and 5 had other pathologies. All these cases were surgically decompressed posteriorly and the results compared.
While results of surgery in patients with Koch's were good, with 7 of the 9 patients showing full recovery, outcome in patients with compression due to other causes (tumor/pyogenic infection) was not very satisfactory even after adequate mechanical decompression, with 3 of the 5 cases remaining paraplegic even after surgery.
Posterior cord compression due to nontuberculous causes frequently mimics the picture of Koch's both clinically and radiologically. Prognosis of surgical decompression is good in tuberculous compression but not in other cases.

ABSTRACT: Tuberculous involvement of the brain and spinal cord are common neurological disorders in developing countries and have recently shown a resurgence in developed ones. Tuberculous meningitis is an important manifestation and is associated with high morbidity and mortality. Diagnosis is based on clinical features, cerebrospinal fluid changes, and imaging characteristics. Bacteriological confirmation is not possible in all cases as serological tests do not have sufficient sensitivity and specificity. The polymerase chain reaction shows promise for the future. Appropriate chemotherapeutic agents should be administered as early as possible, although there is no unanimity concerning chemotherapeutic regimens or optimal duration of treatment. The patient's clinical stage at presentation is the most important prognostic factor. The role of corticosteroids is controversial but they should be administered to all patients presenting in stage III. Surgical procedures are directed at management of the hydrocephalus. Focal lesions, intracranial tuberculomas, and tuberculous abscesses, are usually located in cerebral or cerebellar hemispheres, uncommonly in brainstem and very rarely in spinal cord. They do not usually require surgical intervention and respond well to antituberculous treatment, along with corticosteroids.Postgraduate Medical Journal 04/1999; 75(881):133-40. · 1.61 Impact Factor

ABSTRACT: FNAC is a simple diagnostic tool for the initial evaluation of various deep seated pathological lesions. This study describes the applicability and practical aspects of the technique in establishing the diagnosis of spinal tuberculosis (TB) with the aid of radiographic guidance. The study was conducted in a major teaching hospital in Kuwait between the years 1985 and 1994. Twenty-nine patients (M:F = 18:11 and age range 8-72 years) with clinically and/or radiologically suspected spinal TB were seen in the Department of Cytology, Mubarak Al Kabeer Hospital. The patients were re-examined by either computed tomography (CT) scanning (n = 19) or fluoroscopy (n = 10) to localize the lesion for FNAC. FNAC smears were routinely stained with Papanicolaou and Diff Quik stains and one smear of each case was stained with Ziehl-Neelsen (Z-N) stain for acid-fast bacilli (AFB). Aspirated purulent material or syringe washings of dry aspirates were also submitted for microbiological cultures including AFB. Radiological and cytological findings were recorded in each case. Radiological findings included: bony rarefaction and destruction (93.1%), narrowed disc space (89.7%), soft tissue calcification (65.5%) and para-vertebral abscess formation (51.7%). Cytological findings included: epithelioid cell granulomas (89.7%), granular necrotic background (82.8%) and lymphocytic infiltration (75.9%). Smears were positive for AFB in 51.7% of cases. A positive AFB culture was obtained in 82.8% of cases, including all cases with positive AFB on smear by Z-N stain. Radiologically guided FNAC with AFB culture is a simple, reliable and practical approach to diagnosing spinal TB lesions. With a high diagnostic yield, it allows immediate initiation of specific treatment, helps to avoid invasive diagnostic procedures, and decreases hospitalization time.Cytopathology 12/1999; 10(6):390-401. · 1.71 Impact Factor
