AbstractWe report a 85-year-old woman who died after one year history of convulsion, dementia, and consciousness disturbance. She was apparently well until January 6, 1995 when she was 85 year old; on that evening, she suddenly stated that some one was in her room and she became confused. A local MD gave her diazepam and she fell into sleep. At 3 o'clock in the following morning, she developed tonic-clonic convulsion in her right lower extremity which showed a march to her right upper extremity and the left lower extremity. She was admitted to our hospital. On admission, she was comatose with respiratory acidosis. She was intubated and placed on a ventilator. She was treated with intravenous phenytoin. She gradually gained consciousness and became alert. Respiration became normal. Her MRI revealed ventricular dilatation, fronto-parietal cortical atrophy, and a T1-low and T2-high signal intensity lesion in the left occipital lobe. She was discharged for out patient follow-up on February 4, 1995. Since then, she noted loss of memory and small step gait. A follow-up CT scan revealed a mass lesion which showed a ring-shaped enhancement in the left occipital lobe and was admitted again. On admission, she was alert but markedly demented. The optic fundi was unremarkable, but she appeared to have right homonymous hemianopsia. No motor weakness was noted. In Gd-DTPA enhanced MRI, the above tumor showed a ring enhancement. The diagnosis of glioblastoma was entertained, however, considering her age, she was treated with intravenous glycerol and intramuscular steroid. She was discharged for out-patient follow-up on July 15, 1995. Her gait disturbance had progressively become worse and she developed nausea and vomiting and was admitted again on October 2, 1995. On admission, she was somnolent and markedly demented. Brain stem responses were retained normally. She was unable to stand or walk. Deep tendon reflexes were slightly increased in the right upper extremity and the plantar response was extensor on the right. Her hospital course was complicated by respiratory tract infection and respiratory acidosis. She expired on November 2, 1995. The patient was discussed in a neurological CPC and the chief discussant arrived at the conclusion that she had a glioblastoma involving the left occipital lobe and the adjacent areas. Post-mortem examination revealed an infiltrating tumor in the left occipital lobe. On microscopic examination, the tumor was very cellular; nuclear atypism was marked and tumor cells undergoing mitosis were seen. In some areas, capillary proliferation was seen. Histologic characteristics were consistent with glioblastoma.
