Diagnosis With Brief Discussion
- Diagnosis
- Castleman disease, multicentric, hyaline vascular type
- Radiologic Findings
- Figs 1-1. Chest PA shows right hilar enlargement and widening of the right paratracheal stripe, measuring about 3.5cm.
Fig 2-1,2,3,4,5. Axial and coronal reformatted images of MDCT demonstrate the homogenously enhancing lymphadenopathy in the right hilum, mediastinum and the right supraclavicular area. The mean pre- and postcontrast attenuation values were 40 and 140HU.
Excisional biopsy of the right supraclavicular lymph node demonstrated Castleman disease, hyaline vascular type.
- Brief Review
- Castleman disease is a non-clonal lymphoproliferative disorder. It is one of the more common causes of non-neoplastic lymphadenopathy. Two classification systems exist for Castleman disease: the older morphologic classification and the more recent histopathogenetic classification.
The morphologic classification distinguishes between unicentric and multicentric Castleman disease on the basis of the extent of local lymph node involvement. The histopathogenetic classification distinguishes hyaline vascular type, plasma cell type, human herpesvirus 8 (HHV-8)–associated Castleman disease, and multicentric Castleman disease not otherwise specified.
The classic CT appearance of hyaline vascular Castleman disease is a solitary enlarged lymph node or localized nodal masses that demonstrates homogeneous intense enhancement after contrast material administration. Three patterns of involvement have been described, including a solitary noninvasive mass (50% of cases), a dominant infiltrative mass with associated lymphadenopathy (40% of cases), and matted lymphadenopathy without a dominant mass (10% of cases).
The multicentric, hyaline vascular variant of Castleman disease has rarely been reported in the literature. Multicentric Castleman disease runs a more aggressive course and can progress to non-Hodgkin’s lymphoma.
