ABSTRACT

In China, tuberculosis (TB) is endemic and the Bacillus Callmette-Güerin (BCG) vaccine is administered to all the newborns, which may lead to BCG infection in patients with chronic granulomatous disease (CGD). Infection of BCG/TB in CGD patients can be fatal and pulmonary is the most affected organ. Our objective was to assess the imaging of pulmonary BCG/TB infection in CGD. We screened 169 CGD patients and identified the patients with pulmonary BCG/TB infection. BCG infection was diagnosis according to the vaccination history, local infection manifestation, acid-fast bacilli staining, specific polymerase chain reaction, and/or spoligotyping. PPD, T-SPOT and acid-fast bacilli staining were used for diagnosis of TB. Totally 58 patients were identified, including TB (n = 7), solely BCG (n = 18), BCG + bacterial (n = 20), and BCG + fungi (n = 13). The onset of BCG disease was much earlier than TB. For those patients only with BCG, lymphadenopathy was the first and most prevalent feature. The most found location was the left axilla, followed by the ipsilateral cervical areas and mediastinal or hilar area. On chest CT, ground-glass opacities, multiple nodules and pulmonary scarring were the most common findings. For TB patients, the pulmonary infections were more serious, including large masses, severe lymphadenopathy, and extensive pulmonary fibrosis. Pulmonary infection of BCG were more common than TB in CGD patients, but much less severe.

ABSTRACT

Chronic granulomatous disease (CGD) is characterized by recurrent infections and granuloma formation in multiple organs, especially the lung. We aimed to investigate pulmonary manifestations by computed tomography (CT). In total, 100 patients with 117 episodes of pulmonary infection were included. Chest CT scans of every episode were analyzed. Random nodules were the most common findings (79.49%), followed by ground-grass opacities (74.36%), focal consolidations (62.39%), and masses (59.83%). Cavities (12.82%) and multiple small abscesses (17.09%) could be found in the consolidations and masses. CT revealed interstitial pneumonia with tree-in-bud opacities (17.09%), interlobular septal thickening (23.08%) and emphysema (35.04%), which were more severe in the bilateral upper lobes. Mediastinal and hilar lymphadenopathy (78.63%) and axillary lymphadenopathy (65.81%) were common. Fungal infection (n = 27) was the most common and presented with multiple nodules and masses. Approximately 1/4 of fungal infections had interstitial pneumonia. In Staphylococcus aureus (n = 6) and Klebsiella pneumoniae (n = 3) infections, large areas of consolidation were common. In tuberculosis infection, the pulmonary infections were more severe and complex. For Bacillus Calmette-Guérin disease, left-sided axillary lymphadenopathy was a characteristic manifestation. CT images of CGD demonstrated variable pulmonary abnormalities. The main infectious organisms have unique imaging features.
