Hyperviscosity syndrome associated with lymphoplasmacytic lymphoma with central nervous system involvement
C. Advise urgent plasmapheresis in consultation with oncology
Monoclonal and polyclonal paraproteinemias, such as lymphoplasmacytic lymphoma and multiple myeloma, are frequently associated with hyperviscosity syndrome (HVS).1- 4 This most commonly presents with mucosal bleeding, visual disturbances, and neurological symptoms.5 Up to 48% of patients with Waldenström macroglobulinemia, a type of lymphoplasmacytic lymphoma, show signs of HVS on fundus examination, including peripheral and central dot-blot hemorrhages, dilated retinal veins, tortuous retinal vasculature, and optic disc edema.2 Hyperviscosity syndrome is an oncologic emergency, and prompt identification and treatment is essential.1,6,7 Because patients with HVS often present with visual symptoms, ophthalmologists should keep HVS on the differential diagnosis for bilateral optic nerve edema with vascular congestion and tortuosity. If HVS is identified in time, plasmapheresis can reverse associated retinopathy and prevent other complications (eg, cerebral stroke).8
