rash

Diagnosis?
VZV
VZV
VZV infections of the nervous system
 Inflammation, hemorrhage and necrosis in spinal
ganglia
 Polyradiculitis
 Myelitis
 Meningitis
 Encephalitis
- Large vessel disease
- Small vessel vasculopathy
- Ventriculitis/periventriculits
- Mixed patterns
Large vessel disease
 Vessel wall inflammation,
necrotizing vasculitis,
thrombosis
 Bland or hemorrhagic infarctions
in distribution of large or
medium-sized arteries
 Vasculopathy with fibrointimal
proliferation but without
inflammation
 Immunocompetent and
immunosuppressed patients
Kleinschmidt-DeMasters, Arch Pathol Lab Med 2001
Small vessel vasculopathy
 Variable lymphocytic infiltrate and endothelial
swelling
 Often associated with infection of oligodendrocytes
 Mixed ischemic/demyelinating
lesions near cortical gray/white
junction
 Intranuclear viral inclusions
more readily identified
 Lesions often lack
significant inflammation
Kleinschmidt-DeMasters, Arch Pathol Lab Med 2001
Ventriculitis/periventriculitis
 Rare in pure form
 Infection of ependymal cells
VZV ISH
Kleinschmidt-DeMasters, Arch Pathol Lab Med 2001
Final diagnosis
 Varicella zoster radiculitis, meningitis and
vasculitis associated with intraparenchymal
hemorrhage
