title: [A 59-year-old woman with recurrent convulsive seizures, cerebral infarctions, dementia, and intracranial calcifications].
abstract: A 59-year-old woman with recurrent seizures and progressive dementia is reported. Her past history and familial history were unremarkable. She became short-tempered at 56 years old (Oct. 1991). She had the first seizure attack and was admitted to a hospital at March 4, 1993, with prolonged disturbance of consciousness and subsequent mental deterioration. Her brain CT showed multiple small calcifications in the subcortical white matter and pons. The laboratory data including blood count, serum chemistry, serological studies and CSF was normal. MRI and digital subtraction angiography of the cranial vessels were unremarkable. There was a decrease in accumulation in the right cerebral hemisphere on 123I IMP SPECT. Despite anti-convulsant therapy, she had recurrent seizures several times, with gradual worsening of her mental state. She had the latest seizure attack and was transferred to Matsusaka Chuo Hospital, on August 29, 1993. After the attack she had been in the apallic state, and died on Nov. 13, 1995. This case was discussed in a neurological CPC. The discussants suggested that the isolated angiitis of the central nervous system caused secondary seizures and cerebral infarctions. Post-mortem examination revealed the CNS findings of vasculitis at various stages, calcification or mineralization mainly in the subcortical white matter and pons, massive cerebral infarctions with massive exudate, fresh and old small bleedings and exudate around the inflamed or calcified vessels. The white matter degeneration resembled that of Binswanger leukoencephalopathy. The final pathological diagnosis was isolated angiitis of the central nervous system since there was no inflammatory changes or atherosclerotic change of the blood vessels in the extracranial organs.
