Silent intravascular lymphoma initially manifesting as a unilateral adrenal incidentaloma.

[adrenal incidentaloma]

Intravascular large B-cell lymphoma (IVLBCL ) is a rare subtype of malignant lymphoma . Although the involvement of adrenal glands in IVLBCL is often observed , primary adrenal IVLBCL is rare . Most reported cases of adrenal IVLBCL showed bilateral lesions resulting in rapidly progressive adrenal failure and poor prognosis . Here , we report a case of slowly progressive primary adrenal IVLBCL manifesting initially with unilateral adrenal incidentaloma . This case is a silent IVLBCL and shows that the enlargement of both adrenal glands can be followed .
