Resistant Hypertension in an Obese Patient With Obvious Obstructive Sleep Apnea and Occult Pheochromocytoma

Abstract

We report the case of a 34-year-old male patient who presented with generalized weakness, poorly controlled hypertension, nocturnal hypertension spikes, and morning headaches. The history of resistant hypertension, obesity, enlarged neck size, and loud irregular snoring strongly suggested obstructive sleep apnea (OSA). To exclude other possible causes of resistant hypertension, the patient underwent an abdominal ultrasound examination, which revealed a lesion in the left adrenal gland area. A pheochromocytoma was successfully removed via laparoscopic adrenalectomy, and both his hypertension and OSA responded dramatically. This case highlights the importance of excluding all causes of resistant hypertension regardless of the initial diagnosis.
