Paraganglioma in a young patient with asymptomatic severe hypertension: a case report and review of the literature.

We present a case of a 19-year old woman who was admitted to our department with a recently, and incidentally, diagnosed severe hypertension [220/140 mmHg systolic/diastolic blood pressure (BP)]. The patient was asymptomatic. The laboratory investigation demonstrated both elevated plasma norepinephrine (1807 pg/ml, normal range 120-350 pg/ml) and 24h urinary free catecholamines (483 µg/24h, normal range <150 µg/24h), making the diagnosis of a catecholamineproducing tumor highly probable.
