Chest radiographic findings in Neurotuberculosis without pulmonary signs and symptoms.
J Coll Physicians Surg Pak Jan ;18(1):27-30.

Objective: To determine the chest radiographic findings in patients of adult neurotuberculosis, with no pulmonary signs and symptoms. Study Design: Descriptive study. Place and Duration of Study: Department of Neurology, Pakistan Institute of Medical Sciences, Islamabad, Pakistan, from January 2004 to January 2006. Patients and Methods: A total of 100 patients fulfilling pre-defined criteria of neurotuberculosis were included. Chest radiographic (CXR) evidence of pulmonary TB was looked for in those patients and its frequency, pattern and association with the clinical grades at presentation was determined by using Chi-square test. Results: Out of the 100 patients of neurotuberculosis, with no clinical evidence of pulmonary TB, radiographic evidence of pulmonary TB was seen in only 30% patients. The predominant patterns on CXR were apical infiltration (26.6%), miliary mottling (20%) and hilar enlargement (16.6%). Positive CXR was found in 16.7% patients in clinical grade I and 40% and 43.3% in patients in grade II and III respectively. There was a strong association of grade II and grade III with positive chest radiographic findings (p= 0.03). Conclusion: Patients of neurotuberculosis may have chest radiographic evidence of pulmonary TB even in the absence of pulmonary signs and symptoms at presentation. There is a strong association of clinical grade II and grade III with positive chest radiographic findings.
