Radiology of pulmonary Mycobacterium avium- intracellulare complex

摘要: Although the radiographic appearance of pulmonary MAC infection in immunocompetent host can be varied, there are several generalizations that made. The classic is indistinguishable from tuberculosis. form seen most commonly males and typically associated with other predisposing diseases, especially chronic obstructive disease. Most patients have upper lobe disease pleural thickening. Widespread common, as cavitation. Pleural effusions adenopathy uncommon. Lady Windermere syndrome a special primarily middle-aged elderly women. findings bronchiectasis small nodules, predominately located within middle lingula. combination involving exclusively, or primarily, right lingula highly suggestive MAC, even face negative sputum cultures. Pulmonary immunocompromised patient generally reflects widespread systemic As such, variable. Diffuse opacities common features. Plain radiographs frequently normal despite active infection. Regardless clinical situation, often omitted differential when characteristic. In general, abnormalities identified consistent granulomatous infection, needs to considered along tuberculosis fungal Especially stability over years does not exclude may diagnosis but correlation microbiological data necessary confirm diagnosis.
