Abstract

Krabbe disease is a rare autosomal recessive disorder clinically characterized by retardation in motor development, prominent spasticity, seizures, and optic atrophy. Pathologically, there are many globoid cells in the white matter, in addition to the lack of myelin and the presence of severe gliosis. Hence Krabbe disease is known as globoid cell leukodystrophy. Biochemically, the primary enzymatic deficiency in Krabbe disease is galactocerebroside beta-galactosidase. Patients with Krabbe disease can be subdivided into the early-onset type and late-onset type, according to the onset of clinical manifestations. Most patients with early-onset type die before their second birthday. We describe a girl with Krabbe disease associated with uncontrolled seizures, which was confirmed with biochemical study and MRI. The clinical findings of this patient included hyperirritability, scissoring of the legs, flexion of arm, and clenching of the fists, and generalized tonic seizures. EEG showed hypsarrhythmia, and MRI demonstrated degenerative white matter changes in bilateral periventricular white matter, posterior rim of internal capsule, basal ganglia and brain stem on T2W1 and FLAIR image. The diagnosis was based on clinical features of progressive neurologic deterioration in conjunction with low galactocerebroside beta-galactosidase activity.

저자들은 뇌성마비로 진단받고 치료중 조절되지 않은 경련을 주소로 본과로 전원되어 자기 공명영상 촬영과 효소 측정법으로 Krabbe병의 조기 발현형으로 진단 받은 환자 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
