Middle aortic syndrome in a paediatric patient with Williams syndrome: a case report

Middle aortic syndrome is rare cause of secondary hypertension, typically manifesting in childhood or early adolescence. It involves obstructive narrowing of the aorta, often occurring in the distal thoracic and abdominal aorta and its major branches. While the exact cause of middle aortic syndrome is not fully understood, it has been linked to hereditary genetic conditions such as Williams syndrome. This case report describes a 16-year-old female with Williams syndrome who presented with abdominal pain and hematochezia. CT angiography revealed moderate narrowing of the abdominal aorta, consistent with a diagnosis of middle aortic syndrome.
