Table 1 General clinical findings of the selected group patients (n = 60)

From: Reliability of MRI in detection and differentiation of acute neonatal/pediatric encephalopathy causes among neonatal/pediatric intensive care unit patients



Clinical key findings

1. Hypoxic ischemia injury (HII)

39 (65%)

Varying degree of encephalopathy according to its severity

2. Metachromatic leukodystrophy

6 (10%)

Autosomal recessive (AR), motor signs of acute peripheral neuropathy, deterioration in intellect, speech, and coordination, gait disturbance, quadriplegia in 2, and blindness in 1 patient. Death occurred in 2 patients of them after 6 months of initial admission.


4 (6.7%)

AR, early onset encephalopathy (before the age of 4 years), and febrile illness progress to acute encephalopathy, dystonia, ataxia, and seizures and death if the patients were not treated with biotin and thiamine supplements

4. Leigh disease

4 (6.7%)

Hypotonia, ataxia, ptosis, ophthalmoplegia, and dystonia

5. Periventricular leukomalacia (PVL)

3 (5%)

Premature (33–36 weeks of gestation) all showed delayed milestones


2 (3.3%)

Healthy at birth with early normal development, then growth delay, seizures, episodic vomiting, and recurrent cerebral stroke-like insult

7. Non-ketotic hyperglycinemia

2 (3.3%)

Acute encephalopathy shortly after delivery
