%X <B>BACKGROUND: </B>Turner syndrome is characterized by complete or partial loss of the second sex chromosome. In patients with Turner syndrome, hypertension is well described. However, the literature regarding malignant hypertension is scarce. Therefore, an accurate and timely diagnosis and treatment are important.<BR><B>METHODS: </B>A 13-year-old female with Turner syndrome presented to the emergency department with malignant hypertension, headache, spraying vomiting, convulsion, and loss of consciousness. Considering her medical history, symptoms, and auxiliary examination, secondary hypertension (primary reninism) was suspected, but without any occupying or hyperplasia in renal and adrenal.<BR><B>METHODS: </B>A type of secondary hypertension, primary reninism.<BR><B>METHODS: </B>The patient was immediately transferred to the pediatric intensive care unit. Subsequently, she was given nifedipine 0.35 mg/kg and captopril 0.35mg/kg to reduce blood pressure (BP), mannitol and furosemide to reduce cranial pressure, and phenobarbital and midazolam to terminate restlessness successively. Three hours later, the BP was consistently higher than 170/120 mm Hg, sodium nitroprusside was pumped intravenously, then, giving oral drug transition. Finally, she was given Valsartan-Amlodipine Tablets (I) (80 mg valsartan and 5 mg amlodipine per day) and bisoprolol (2.5 mg per day).<BR><B>RESULTS: </B>For 2.5 years of follow-up, the BP reduced to 110-130/60-85 mm Hg, heart rate ranged between 65 and 80 bpm, and she could go to school without any headache, convulsion, and syncope.<BR><B>CONCLUSIONS: </B>The clinical phenotype of Turner syndrome is complex and varied, affecting multiple systems and organs. Turner syndrome with malignant hypertension is rare, so we should systematically evaluate secondary hypertension, target-organ damage, and accompanied by standard management when Turner syndrome presents with hypertension.
