Abstract
Chronic granulomatous disease (CGD) is a group of rare primary inborn errors of immunity characterised by a defect in the phagocyte respiratory burst, which leads to severe and life-threatening infective and inflammatory complications. Despite recent advances in our understanding of the genetic and molecular pathophysiology of X-linked and autosomal recessive CGD, and growth in the availability of functional and genetic testing, there remain significant barriers to early and accurate diagnosis. In the current review, we provide an up-to-date summary of CGD pathophysiology, underpinning current methods of diagnostic testing for CGD and closely related disorders. We present an overview of the benefits of early diagnosis and when to suspect and test for CGD. We discuss current and historical methods for functional testing of NADPH oxidase activity, as well as assays for measuring protein expression of NADPH oxidase subunits. Lastly, we focus on genetic and genomic methods employed to diagnose CGD, including gene-targeted panels, comprehensive genomic testing and ancillary methods. Throughout, we highlight general limitations of testing, and caveats specific to interpretation of results in the context of CGD and related disorders, and provide an outlook for newborn screening and the future.

[PMID: 38668402 PMCID: PMC11054070 DOI: 10.3390/tomography10040045] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 04/07/2024] [Accepted: 04/15/2024] [Indexed: 04/29/2024] Open
Abstract
Interlobular septa thickening (ILST) is a common and easily recognized feature on computed tomography (CT) images in many lung disorders. ILST thickening can be smooth (most common), nodular, or irregular. Smooth ILST can be seen in pulmonary edema, pulmonary alveolar proteinosis, and lymphangitic spread of tumors. Nodular ILST can be seen in the lymphangitic spread of tumors, sarcoidosis, and silicosis. Irregular ILST is a finding suggestive of interstitial fibrosis, which is a common finding in fibrotic lung diseases, including sarcoidosis and usual interstitial pneumonia. Pulmonary edema and lymphangitic spread of tumors are the commonly encountered causes of ILST. It is important to narrow down the differential diagnosis as much as possible by assessing the appearance and distribution of ILST, as well as other pulmonary and extrapulmonary findings. This review will focus on the CT characterization of the secondary pulmonary lobule and ILST. Various uncommon causes of ILST will be discussed, including infections, interstitial pneumonia, depositional/infiltrative conditions, inhalational disorders, malignancies, congenital/inherited conditions, and iatrogenic causes. Awareness of the imaging appearance and various causes of ILST allows for a systematic approach, which is important for a timely diagnosis. This study highlights the importance of a structured approach to CT scan analysis that considers ILST characteristics, associated findings, and differential diagnostic considerations to facilitate accurate diagnoses.

Abstract
OBJECTIVES To describe prevalence of various imaging findings in chronic granulomatous disease (CGD) patients; and find imaging biomarkers for differentiating chest infections caused by different micro-organisms. METHODS A retrospective study was conducted on 15 patients (49 scans) with proven CGD. Scans which had a correlative microbiological diagnosis for organisms were included in the analysis. The scans were reviewed by 3 radiologists on a predefined proforma, under the lung parenchymal, airway, pleural, mediastinal, and extrathoracic abnormalities. Analysis of various imaging parameters on a semiquantitative scale was performed, followed by a correlation of each imaging findings with causative organisms. RESULT The mean age of presentation was nearly 7 y, with a male preponderance. Definitive proof of causative organisms was obtained in 22 scans. Bacterial infection was found in 7, fungal in 12, tubercular in 2, and viral in 1 scan. Most prevalent thoracic imaging manifestations included lymphadenopathy (commonest), consolidation, nodules, air trapping, and bronchiectasis. Fungal infections showed necrotic conglomerate lymphadenopathy, cavitating nodules, and multilobar consolidation more frequently than bacterial infections (though not statistically significant). Abscesses and lymphadenopathy were the most common extrathoracic manifestations. CONCLUSION In patients with CGD, multifocal or multilobar consolidation, mass-like consolidation, cavitating nodules, and conglomerate necrotic lymphadenopathy should alert the radiologist to a possible fungal cause.

Abstract
BACKGROUND Granulomatous inflammation results from various causes including infections and allergic reactions. It can appear as high signal intensity in T2-weighted or contrast-enhanced T1-weighted magnetic resonance imaging (MRI). Here, we describe a case of granulomatous inflammation looking like a hematoma on an ascending aortic graft in MRI. CASE PRESENTATION A 75-year-old female was undergoing assessment for chest pain. She had a history of hemi-arch replacement for aortic dissection 10 years earlier. The initial chest computed tomography and subsequent chest MRI were suggestive of a hematoma, implying a pseudoaneurysm of the thoracic aorta, which is associated with high mortality in reoperation. Through redo median sternotomy, severe adhesion was found in the retrosternal space. A sac in the pericardial space contained yellowish and pus-like material, confirming that there was no hematoma around the ascending aortic graft. The pathologic finding was chronic necrotizing granulomatous inflammation. Microbiological tests including polymerase chain reaction analysis were negative. CONCLUSION Our experience indicates that an MRI finding of a hematoma at the site long after cardiovascular surgery suggests that there may be granulomatous inflammation.

Abstract
BACKGROUND Chronic granulomatous disease (CGD) is a rare primary immunodeficiency which can lead to gastrointestinal (GI) complications including inflammatory bowel disease. Radiographic findings in this cohort have not been well described. AIMS To describe the frequency and spectrum of gastrointestinal abnormalities seen on computed tomography (CT) in patients with CGD and determine whether radiography was predictive of endoscopic or histopathologic inflammatory findings. METHODS A retrospective review was conducted on 141 consecutive CGD patients seen at the National Institutes of Health between 1988 and 2011. All corresponding CTs were reviewed for gastrointestinal abnormalities including wall thickening. Endoscopic and histopathologic findings were reviewed in subjects with documented endoscopy within 30 days of an imaging study. Findings were compared between patients with and without wall thickening on CT to determine whether bowel wall thickening was predictive of endoscopic or histologic inflammatory findings. RESULTS Two hundred and ninety-two CTs were reviewed. GI wall thickening was present on CT in 61% of patients (n = 86). Among a subgroup of 20 patients who underwent endoscopy at the time of their imaging, there was a statistically significant correlation between radiographic gastrointestinal wall thickening and endoscopic inflammation in the same intestinal segment (p = 0.035). Additionally, there was a significant correlation between radiographic gastrointestinal wall thickening and inflammatory features on histopathology (p = 0.02). CONCLUSIONS GI abnormalities are commonly observed on CT in CGD patients. Bowel wall thickening correlates with endoscopic and histopathologic evidence of inflammation. These findings may be used to better facilitate directed endoscopic assessment and histopathologic sampling in patients with CGD.

Abstract
Primary immunodeficiency disorders (PIDs), which are humoral, combined, and innate defects of the immune system, are relatively uncommon and may go undiagnosed in patients experiencing recurrent infections, resulting in increased morbidity and mortality. PIDs are clinically characterized by a broad spectrum of disorders, including repeated infections, autoimmune disorders, lymphoproliferative diseases, congenital anomalies, and increased risk of malignancy. Cardiothoracic imaging plays a crucial role in the diagnosis of PIDs owing to the high rates of repeated respiratory infections leading to bronchiectasis and other forms of chronic lung disease. Although PIDs as a group may seem similar in terms of radiologic features and clinical manifestations, there are specific entities that are pertinent to each PID on an individual level. For example, patients with common variable immunodeficiency may develop a unique granulomatous lymphocytic interstitial lung disease, and Good syndrome is associated with thymoma. Familiarity with the imaging characteristics of these disorders may expedite diagnosis and prognostication, and better direct therapy. Reviewing the thoracic manifestations of all PIDs is beyond the scope of this article; thus, the focus herein is on discussing the thoracic manifestations of the most common PIDs and their imaging features. © RSNA, 2021An earlier incorrect version appeared online.

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.
