Then to regional nodes. The initial pulmonary inflammatory exudate produces localized air-space disease that can involve an entire segment or lobe. A pleural effusion may also be present. Lymph node enlargement can cause airway obstruction by extrinsic compression, either with resultant atelectasis or air-trapping. Clinically, the child is often not acutely ill.
Tuberculous meningitis causes more deaths than any other form of tuberculosis.
It often does not have the typical symptoms of fever or headache. This meningitis probably results from the rupture of a tuberculoma. A gelatinous exudate fills the basal cisterns, which will enhance with contrast. When the tuberculoma is over 2 cm., it tends to have a thick enhancing ring with little or no surrounding edema. Solitary lesions are more frequent below the tentorium.
