Diffuse arterial calcified elastopathy--a new cause of renovascular hypertension in children
Insights
Diffuse arterial calcified elastopathy, a rare condition, affects pediatric patients with severe renovascular hypertension. This study identifies a unique ultrasound pattern and confirms arterial calcification, highlighting potential etiological links.
Area of Science:
- Vascular Biology
- Pediatric Nephrology
- Radiology
Background:
- Diffuse arterial calcified elastopathy is a rare condition.
- Severe renovascular hypertension in children necessitates understanding underlying causes.
- Identifying novel clinicopathological syndromes is crucial for pediatric health.
Observation:
- Six pediatric patients with severe renovascular hypertension exhibited diffuse arterial calcified elastopathy.
- Renal ultrasonography revealed a distinct 'dotted corticomedullary junction' pattern.
- Superficial temporal artery biopsies confirmed calcification within the elastic layers of muscular arteries.
Findings:
- The 'dotted corticomedullary junction' on renal ultrasound is a characteristic finding in this condition.
- Arterial calcification involves the elastic layers, indicating a widespread vascular process.
- Etiological investigations identified pseudoxanthoma elasticum in two patients, suggesting potential heterogeneity.
Implications:
- This study defines a clinicopathological syndrome associated with pediatric renovascular hypertension.
- The characteristic ultrasound pattern may aid in early diagnosis.
- Further research into the heterogeneous etiology of this condition is warranted.
Abstract:
Diffuse arterial calcified elastopathy was observed in 6 pediatric patients presenting with severe renovascular hypertension. Renal ultrasonography showed a characteristic pattern, the dotted corticomedullary junction, related to the increased echogenicity of the interlobar and/or arcuate arteries. Superficial temporal artery biopsy demonstrated the presence and the extension of the calcifying process involving the elastic layers of the muscular arteries. This clinicopathological syndrome may be heterogeneous from an etiological point of view: etiologic investigations led to the diagnosis of pseudoxanthoma elasticum in 2 patients; no etiologic cause could be found in the others.
