A 30-year-old woman suffered from a progressive extrapyramidal syndrome, myoclonic jerks, spasticity, and organic brain syndrome; she was clinically suspected to suffer from Creutzfeldt-Jakob disease and died after 4 years of illness. At autopsy, widespread dystrophic axons and Lewy bodies (LBs) were found in her brain. Neuronal loss and diffuse reactive astrogliosis involved the gray matter including the cerebral cortex. Dystrophic axons occurred throughout the nervous system except for the cerebellar cortex and peripheral nerves. LBs involved the cerebral cortex as well as subcortical regions including amygdala and claustrum, brainstem including substantia nigra and locus coeruleus, and spinal cord. LBs were distributed extensively enough to be compatible with diffuse Lewy body disease (DLBD). Ubiquitin immunostaining labeled both dystrophic axons and LBs. The combination of neuroaxonal dystrophy and DLBD may result from cytoskeletal pathology which affects both neuronal cell bodies and axons with subsequent deficient proteolysis and ubiquitination.

We present 3 sporadic cases of a subacute to chronic, progressive motor (i.e. weakness, ataxia, spasticity, dysarthria, and dysphagia) and cognitive disorder in adults of both sexes, without proven immunocompromise or malignancy. Neuroimaging studies revealed tiny calcifications with atrophy of the cerebrum, pons, and midbrain in 1 patient, cerebral atrophy in another, and cerebral atrophy and periventricular white matter hyperintensities in the third. Clinical diagnoses included cortico-pontine-cerebellar degeneration, mixed neurodegenerative disorder, progressive supranuclear palsy, diffuse Lewy body disease, and Lyme disease. One atrophic brain revealed widely disseminated, millimeter-sized gray lesions in cerebral white matter and obscured anatomic markings of the basis pontis. The most conspicuous microscopic feature in all was capillaries with focally piled up endothelial nuclei, some of which appeared to be multinucleated, or enlarged, hyperchromatic crescentic single nuclei. Although seen mostly without associated damage, they were also noted with white matter lesions displaying vacuolation, demyelination, spheroids, necrosis, vascular fibrosis, and mineralization; these were most severe in the basis pontis. Immunostains and probes to herpes simplex virus-I, -II, and -8; adenovirus, cytomegalovirus, varicella-zoster, Epstein-Barr virus, measles, JC virus, and herpes hominis virus-6 were negative. Electron microscopy revealed no virions in endothelial cells with multilobed or multiple nuclei and duplicated basal laminae. However, mycoplasma-like bodies, mostly 400 to 600 nm in size, were found in endothelial cell cytoplasm and capillary lumina. Platelets adhered to affected endothelial cells. Polymerase chain reaction and immunohistochemistry of fixed samples for Mycoplasma fermentans were negative; other species of Mycoplasma remain viable pathogenic candidates.
