CT of Castleman disease in the mediastinum.

ABSTRACT

Castleman disease is a rare lymphoproliferative disease commonly occurring as a benign localized mass of lymph nodes in the mediastinum. Given that Castleman disease presents as asymptomatic or through non-specific thoracic symptoms, detection is considered complex. Ultimately, surgical resection is the preferred course of action with a greater than 90% relapse-free survival and no malignant transformation reported. In this article, we describe the case of a 34-year-old male with an unclear smoking history who was diagnosed with hyaline-vascular Castleman disease. We focus on optimizing diagnosis and management through the application of radiological imaging modalities, including computed tomography scans.
