Summary
Idiopathic arterial calcification in infancy (IACI) typically presents early and is fatal. This report details a rare, later presentation of IACI in a child, highlighting diagnostic clues for this unusual arterial disease.
Area of Science:
- Pediatric Cardiology
- Radiology
- Pathology
Background:
- Idiopathic arterial calcification in infancy (IACI) is a rare, severe condition usually leading to early mortality.
- Diagnosis is often made post-mortem, making early identification challenging.
Observation:
- A 33-month-old child presented with hypertension and cardiac failure, unusual for IACI's typical infantile onset.
- Radiological imaging revealed widespread arterial calcification.
- Renal biopsy showed histological features consistent with IACI, despite normal calcium-phosphate levels and no other identifiable cause.
Findings:
- This case represents a unique, late-onset presentation of idiopathic arterial calcification in infancy.
- The calcium-phosphate axis was normal, ruling out common metabolic causes.
- Histological findings confirmed arterial calcification similar to typical infantile cases.
Implications:
- Early suspicion of IACI is crucial in children with unexplained cardiac or respiratory issues and arterial calcification.
- Imaging modalities like ultrasound and CT are sensitive for detecting arterial calcification.
- Recognizing late presentations can improve diagnostic timelines and management strategies for this rare disorder.
