Acute encephalopathy in two cases with severe congenital hydrocephalus.

Abstract

We report acute encephalopathy in two cases with severe congenital hydrocephalus. Case 1 was a 23-month-old girl, born at of 36weeks gestation and delivered by cesarean section due to congenital hydrocephalus. Magnetic resonance imaging (MRI) showed prominent ventricular dilation associated with hydrocephalus, Dandy-Walker variant and cortical malformation. The blood test for toxoplasmosis, syphilis, varicella-zoster, rubella, cytomegalovirus, and herpes simplex virus (TORCH) complex and various metabolic tests of blood and urine specimens yielded unremarkable results. She was admitted to our hospital for respiratory failure with fever and her clinical course deteriorated, progressing to hemiconvulsion hemiplegia epilepsy syndrome. Case 2 was a 17-month-old boy, born by spontaneous vertex delivery at 39weeks. Severe, asymmetrical ventricular dilation associated with hydrocephalus, cerebellar and brainstem hypoplasia, and punctuate calcifications of the thalamus, third and fourth ventricles, around the aqueduct, were observed on computed tomography (CT). The blood test for TORCH complex and various metabolic tests of blood and urine specimens yielded unremarkable results. He was admitted to our hospital for status epilepticus with fever and his clinical course progressed to hemorrhagic shock and encephalopathy syndrome. In patients with brain disorders, diagnosis and treatment are likely to be delayed and prognosis may thereby be worsened. When status epileptics or prolonged coma manifests even in patients with severe brain disorders, we must consider encephalopathy in the differential diagnosis.
