Diagnosis With Brief Discussion
- Diagnosis
- Castlemen disease, Hyaline vascular type
- Radiologic Findings
- Chest radiograph shows mediastinal widening. On CT, multiple variable sized lymphadenopathy noted in left anterior mediastinum, associated with surrounding fat infiltration. Biopsy was performed, and the pathologic diagnosis was Castleman disease, hyaline vascular type (CD3 and CD20: reactive pattern, CK (AE1/3): negative).
- Brief Review
- Castleman disease is an uncommon nonclonal lymphoproliferative disease with benign lymph node hyperplasia. Pathologically there are two types: Hyaline vascular (90%) and plasma cell type. Based on the biological behavior, Castleman disease can be subdivided into unicentric form and multicentric form.
Unicentric form Multicentric form
Pathology Hyaline vascular type
Occasionally plasma cell type Plasma cell type
Occasionally hyaline vascular type
Age 3rd or 4th decade 6th decade
Clinical course Benign Aggressive
Progression to lymphoma Rare Common
Treatment Surgery Systemic therapy
Castleman disease is most common in thorax (70%), followed by abdomen /retroperitoneum/pelvis (10-15%) and neck (10-15%).
Radiologic manifestations of thoracic Castleman disease can mimic thymoma, lymphoma or neurogenic tumor. Common CT findings of unicentric Casteman disease include 1) solitary, non-invasive mass, 2) dominant mass with involvement of contiguous structures, and 3) matted lymphadenopathy confined to single mediastinal compartment. In contrast, typical CT finding of multicentric Castleman disease is diffuse lymphadenopathy involving multiple anatomic regions.
