Horner Syndrome Following Permcath Insertion in a Child with End-Stage Renal Disease: A Case Report

Horner syndrome, characterized by the triad of unilateral ptosis, miosis, and anhidrosis, typically arises following a stroke, surgical interventions in the neck and chest, or trauma. Horner syndrome is rare in children. This study presents the case of a 9-year-old girl with End-Stage Renal Disease (ESRD) caused by renal hypodysplasia. After permcath insertion, she developed a severe headache and anisocoria, followed by ptosis and a progressively expanding neck hematoma. Physical examination and MRI of the neck revealed that Horner syndrome, caused by hematoma formation following permcath placement, was the diagnosis. Supportive interventions were implemented, leading to significant improvement in Horner syndrome over a six-month period. Complications from permcath insertion can be a cause of Horner syndrome.
