Summary
Acute glomerulonephritis can cause hypertensive encephalopathy, leading to rare cases of temporary cortical blindness in children. Prompt antihypertensive therapy is crucial for vision recovery.
Area of Science:
- Pediatric Nephrology
- Neurology
Background:
- Post-infectious acute glomerulonephritis (AGN) is often associated with hypertension and can lead to hypertensive encephalopathy (HE).
- Neurological complications of HE in children with AGN, such as cortical blindness, are exceptionally rare.
Observation:
- A 10-year-old boy presented with gross hematuria, headache, vomiting, and oliguria, indicative of AGN.
- He subsequently developed transient cortical blindness, a rare complication of HE.
- Cranial MRI revealed occipital lobe abnormalities consistent with hypertensive encephalopathy.
Findings:
- The patient experienced a full visual recovery within 2 days of initiating antihypertensive treatment.
- No seizures were observed during the clinical course.
- Long-term follow-up at 1 year showed complete recovery without residual symptoms.
Implications:
- This case underscores the potential for cortical blindness as a manifestation of HE in pediatric AGN.
- Highlights the critical need for vigilant hypertension management in children with AGN to prevent neurological sequelae.
- Emphasizes the importance of early diagnosis and intervention for HE to ensure favorable outcomes.
