INTRODUCTION: Sural nerve biopsy is an important means of establishing the diagnosis of inflammatory neuropathies. We investigated the diagnostic value of endoneurial edema.
METHODS: Diagnostic sural nerve biopsies from 42 patients with inflammatory and 28 patients with noninflammatory neuropathies were re-evaluated for the presence of endoneurial edema. Edema was assessed on hematoxylin-eosin stained paraffin and frozen sections and on azure II-methylene blue stained semithin sections. We determined the area of endoneurial edema on digitized images in relation to the entire endoneurial area of each fascicle.
RESULTS: Edema was more extensive in neuropathies with short disease duration (≤12 months) as compared to long duration (>12 months; P < 0.01). Edema in inflammatory neuropathies of ≤12 months duration covered a larger area than in noninflammatory neuropathies (P < 0.01), and the extent of edema correlated negatively with disease duration (P < 0.05).
CONCLUSIONS: Endoneurial edema may be a useful additional disease marker in inflammatory neuropathies of recent onset.
