Electron microscopy showed endothelial proliferation accompanied by abnormal accumulation of masses of intracytoplasmic filaments in each case. Of the eleven patients with dysglobulinemia, nine had monoclonal gammopathy and two were found to have polyclonal elevation of gamma globulin levels. Symptoms of neuropathy characteristically preceded detection of serum protein abnormalities by months to years. Nerve fiber lesions involved primarily the axon in four cases; segmental demyelination was the principal abnormality in the other seven. Both abnormalities were present to some degree in all eleven patients. Biphasic myelinopathy with uniform separation of myelin lamellae attributable to globulin deposition was observed in four cases.<\/jats:p><jats:p>The microvascular changes included endothelial cytoplasmic enlargement, virtually obliterating the vessel lumen in many instances, with thickening of pericytes, in which intracytoplasmic filaments were prominent and pinocytotic vesicles numerous. No extracellular filaments were noted, and amyloid stains were negative. Possible effects of these microvascular changes include ischemia resulting from severe vascular luminal narrowing, and altered vascular permeability. Severe loss of axons in this group of neuropathies may be the result of ischemia, whereas altered vascular permeability may admit globulin into the endoneurium, where it may directly affect the myelin sheath and precipitate demyelination.<\/jats:p>","DOI":"10.1002\/ana.410150414","type":"journal-article","created":{"date-parts":[[2005,1,1]],"date-time":"2005-01-01T17:08:31Z","timestamp":1104599311000},"page":"386-394","source":"Crossref","is-referenced-by-count":43,"title":["Microangiopathy of vasa nervorum in dysglobulinemic neuropathy"],"prefix":"10.1002","volume":"15","author":[{"given":"Henry C.","family":"Powell","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moses","family":"Rodriguez","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard A.
