Radiographic Findings in Hyperimmunoglobulin E Syndrome

Area of Science:

• Radiology
• Immunology
• Infectious Diseases

Background:

• Hyperimmunoglobulin E (hyper-IgE) syndrome is a rare primary immunodeficiency.
• Adult presentation of hyper-IgE syndrome is uncommon, with limited radiologic data.
• Understanding the imaging spectrum is crucial for timely diagnosis in adults.

Purpose of the Study:

• To delineate the range of radiologic manifestations of hyper-IgE syndrome in adult patients.
• To correlate imaging findings with clinical and laboratory data.
• To emphasize the importance of recognizing these patterns in a rare disease.

Main Methods:

• Retrospective analysis of imaging findings in five adult patients diagnosed with hyper-IgE syndrome.
• Review of chest X-rays, CT scans, and other relevant imaging modalities.
• Correlation of radiologic findings with confirmed laboratory diagnoses.

Main Results:

• Lung involvement observed in 3 out of 5 patients.
• Paranasal sinus disease identified in 4 out of 5 patients.
• Widespread infectious involvement of soft tissues (5/5), bones (3/5), bursae, tendons, and the respiratory system were the most frequent findings.

Conclusions:

• Radiologic findings in adult hyper-IgE syndrome often involve extensive soft tissue and bone infections.
• Imaging plays a key role in identifying characteristic patterns of this rare condition.
• Early recognition of these radiologic signs can aid in the diagnosis of hyper-IgE syndrome in adults.
