A woman in her 40s was found to have a 37-mm lobulated anterior mediastinal mass with fine calcifications on non-contrast chest CT performed for asthma evaluation. Fat-suppressed T2-weighted MRI showed a hyperintense lesion with internal flow voids, suggesting a hypervascular tumor. Contrast study was not performed due to asthma, and differential diagnosis included thymoma and Castleman disease. Surgical resection confirmed unicentric Castleman disease. Although Castleman disease is a rare mediastinal tumor, this case suggests that it may be diagnosed based on characteristic findings even without contrast imaging.
