Takayasu arteritis presenting with malignant hypertension; a rare manifestation of a rare disease: a case report and review of the literature.

Takayasu arteritis (TA) is a chronic inflammatory and obliterative disease of large vessels, which mainly affects the aorta and its major branches. TA can lead to renal failure and renovascular hypertension in 60% of patients; it is rare in children aged <10 years and, more rarely, it presents with malignant hypertension in the paediatric age group. Here we present a case of 9-year-old boy with TA who presented with malignant hypertension and required surgical intervention to control the blood pressure. Subsequently, his medications were titrated using 24 h ambulatory blood pressure monitoring (ABPM) and is doing well on follow-up.
