Neurological Complications in Pediatric Takayasu Arteritis: Insights from a Single-Center Experience.

Background/

Objectives

Pediatric Takayasu arteritis (PTA) is a rare large-vessel vasculitis with limited data regarding neurological involvement. This study aimed to evaluate neurological manifestations and associated neuroimaging findings in a cohort of children with PTA.

Methods

In this retrospective observational study, 22 patients diagnosed with PTA and followed at a tertiary center between January 2000 and April 2025 were included. Neurological symptoms, examination findings, and neuroimaging data were reviewed. Angiographic involvement was classified according to the Numano classification.

Results

Neurological involvement was identified in 5 patients (22.7%), including ischemic stroke (n = 3) and hypertensive encephalopathy (n = 2). Neurological symptoms were present in 15 patients (68.2%), with headache being the most common manifestation (54%). Other symptoms included dizziness, paresthesia, visual disturbances, syncope, and seizures. Neuroimaging revealed ischemic lesions in a subset of patients, as well as nonspecific white matter changes. Angiographic evaluation showed a predominance of extensive disease patterns, particularly Type V and Type IV involvement.

Conclusions

Neurological manifestations in pediatric Takayasu arteritis are common but often nonspecific. However, severe complications such as stroke and hypertensive encephalopathy may occur and can be the initial presentation. Careful neurological evaluation and the use of neuroimaging are essential for early detection and appropriate management.
