Overview
Patients with waldenström's macroglobulinemia should have nerve conduction study, antimyelin associated glycoprotein serology[1], and fundoscopy done.[2] Bone marrow aspirate is frequently hypocellular in waldenström's macroglobulinemia. Biopsy specimen is usually hypercellular and infiltrated with lymphoid and plasmacytoid cells. Dutcher bodies (PAS positive Intranuclear vacuoles containing IgM monoclonal protein) are characteristic feature of waldenström's macroglobulinemia.[3]
Other Diagnostic Studies
Other diagnostic studies for Waldenström macroglobulinemia include:
- Nerve conduction tests and electromyography, which demonstrates:
- demyelination with sensory involvement more than motor[1]
- Fundoscopy, which demonstrates:
- Plasma viscosity
- Plasma viscosity should be measured in patients presenting with hyperviscosity syndrome whenever the monoclonal IgM protein spike is >4 g/dL.
- The normal plasma viscosity is 1.8 centipoise.
- Patient presents with hyperviscosity symptoms with viscosity >4 centipoise.
