radiographic appearance of primary TB

What is the radiographic appearance of primary TB?

Primary TB can occur anywhere in the lung. Most cases are asymptomatic and are thus not seen by imaging in the acute stages. Primary TB typically appears as a focal area of consolidation. Cavitation is not a common feature. An associated pleural effusion may be visualized. Rarely, primary TB can result in hematogenous dissemination, marked by multiple tiny randomly distributed miliary pulmonary nodules.
