Sneddon syndrome is a rare, non-inflammatory vasculopathy that generally occurs in the third to fourth decade of life but may rarely present in the pediatric population. It is characterized by the skin finding of livedo racemosa and recurrent ischemic strokes. Other common neurologic manifestations include migraine and early cognitive decline. It may be associated with systemic lupus erythematosus (SLE) and antiphospholipid antibodies, or as in our case, thrombophilia and autoimmune workup may be negative. Optimal treatment for Sneddon syndrome is unknown. Here we report the case of an 18-year-old female, with a 3-year history of livedo racemosa and migraines, who presented with acute expressive aphasia and was found to have an ischemic stroke and an evidence of prior strokes on magnetic resonance imaging (MRI). Autoimmune and cardioembolic causes of stroke were ruled out. Given the findings of livedo racemosa and evidence of recurrent strokes, she was diagnosed with Sneddon Syndrome. Five years earlier, she had been diagnosed with Freiberg disease, which is the avascular necrosis of the second metatarsal head and was likely her first symptom of Sneddon syndrome. This is the first report of Freiberg disease associated with Sneddon syndrome. This paper highlights a rare cause of stroke in the pediatric population as well as the first report of avascular necrosis associated with Sneddon syndrome. Several manifestations of Sneddon syndrome can precede strokes by years. An awareness of those features may allow for the adoption of primary stroke prevention.
