Kojewnikow's Epilepsia Partialis Continua: two cases associated with striatal necrosis.

The authors report two cases of children suffering from Epilepsia Partialis Continua (EPC). The first case concerned a boy primarily affected by abdominal neuroblastoma and secondarily by bilateral EPC; "pallidal posture" was the prominent clinical feature. An acute measles encephalitis was diagnosed and the CT scan showed necrosis of the putamina. The second case concerned a girl suffering from increased intracranial pressure due to suprasellar craniopharyngioma. Seven days after intervention, Diabetes Insipidus and EPC appeared. Enlargement of rolandic and sylvian spaces and lacunar necrosis of the putamen on the left side were also evident on the CT scan. The authors emphasize the significance of occasional metabolic disturbances, especially natremia, in the development of EPC.
