Adult polyglucosan body disease (APBD) is a rare neurological disease, characterized by adult onset (fifth to seventh decades), progressive sensorimotor or pure motor peripheral neuropathy, upper motor neuron symptoms, neurogenic bladder, and cognitive impairment. APBD is confirmed by a sural nerve biopsy that shows the widespread presence of polyglucosan bodies in the nerve. We report a 70 year old male patient who exhibited progressive weakness in all extremities and dementia. His electrodiagnostic studies showed sensorimotor polyneuropathy and muscle pathology that consisted of polyglucosan bodies located in small peripheral nerves. This is the first case of APBD reported in Korea.

    ABSTRACT: Glycogenosis type IV is caused by a deficiency of glycogen branching enzyme (alpha-1,4 glucan 6-transglucosylase). Adult polyglucosan body disease (APBD) may represent a neuropathological hallmark of the adult form of this storage disease of the central nervous system. We analysed a case of a 45-year-old unconscious woman who died three days after admission to the hospital. Neuropathological examination revealed massive accumulation of polyglucosan bodies (PBs) in the cortex and white matter of the whole brain. PBs were located in the processes of neurons, astrocytes and microglial cells. The storage material in the cytoplasm of neurons and glial cells was visible as fine granules. Ultrastructurally, PBs consisted of non-membrane-bound deposits of branched and densely packed filaments, measuring about 7-10 nm in diameter, typical of polyglucosan bodies. APBD patients develop upper and lower neuron disease and dementia, probably secondary to the disruption of neuron and astrocyte functions.

    ABSTRACT: Corpora amylacea (CA) normally accumulate within perivascular, subpial, and subependymal astrocytic processes. CA are associated with a number of conditions including normal aging, hippocampal sclerosis associated with temporal lobe epilepsy, multiple sclerosis, Lafora-type progressive myoclonic epilepsy, and adult polyglucosan body disease. Reports of massive localized accumulation of CA in the brain outside of these conditions are rare. A 49-year-old woman, with a long-standing history of migraine headaches, presented to her primary care provider for increased headache duration. Brain magnetic resonance imaging (MRI) revealed a left parahippocampal lesion, suggestive of low-grade glioma. Given the MRI suggestive of left parahippocampal glioma, left-sided frontotemporal craniotomy was performed for resection of the lesion. Specimens obtained during the operation revealed focal high-density accumulation of CA with no evidence of neoplasm, ischemia, or hypoxic injury. This case illustrates the possibility that localized high-density CA accumulation can present as an intrinsic lesion on brain MRI. CA should be included in the differential diagnosis for patients presenting with brain MRI suggestive of nonenhancing space-occupying lesions.
