Editor-In-Chief: C. Michael Gibson, M.S., M.D. [1]; Associate Editor(s)-in-Chief: Sara Mohsin, M.D.[2]

Overview

Other diagnostic studies for lymphoplasmacytic lymphoma include nerve conduction study, electromyography, funduscopy, plasma viscosity, and mutational analysis.

Other Diagnostic Studies

Other diagnostic studies for lymphoplasmacytic lymphoma include:

Ophthalmoscopic examination revealed dilatation and tortuosity of the retinal veins.

Ophthalmologic findings in the presented case. The optic disk of the left eye is shown. The perivenous sheathing is indicated (black arrow).

One year after therapy. The right fundus exhibited a roundish, subretinal, pseudovitelliform deposit (a). The deposit displayed uneven hyper-autofluorescence on a fundus autofluorescence photograph (c) and uneven staining in fluorescein angiography (e). It was associated with macular edema in an OCT horizontal scan (g). The left eye fundus exhibited a large retinal serous detachment (b), with accumulation of hyper-autofluorescent lipofuscin material in autofluorescence fundus photography (d). Fluorescein angiography was not contributive (f), but OCT showed the absence of central photoreceptors (h).[https://openi.nlm.nih.gov/detailedresult.php?img=PMC3433005_cop-0003-0236-g02&query=waldenstrom+macroglobulinaemia&it=xg&req=4&npos=27 Source: Brolly A. et al, Department of Ophthalmology, APHP, Hôpital Lariboisière, University Paris Diderot, Sorbonne Paris Cité, Bourges, France.
