TY - JOUR T1 - Unusual cause of resistant hypertension in a 33-year-old woman with a palpable parathyroid nodule JF - BMJ Case Reports JO - BMJ Case Reports DO - 10.1136/bcr-2021-244067 VL - 14 IS - 8 SP - e244067 AU - Max Yap AU - Owain Chandler AU - Stanley Savas AU - Dan Xu Y1 - 2021/08/01 UR - http://casereports.bmj.com/content/14/8/e244067.abstract N2 - A 33-year-old woman presented for investigation for a secondary cause of her long-standing treatment-resistant hypertension. Physical examination revealed a palpable thyroid nodule with subsequent ultrasound and CT scan indicating the nodule was of parathyroid origin. A palpable parathyroid nodule is known to be highly suspicious for a parathyroid carcinoma, and it remains a differential until proven otherwise. Histopathology following surgical excision confirmed a parathyroid adenoma, and during subsequent follow-up visits with her general practitioner, her antihypertensive was successfully weaned. We report a case of a large palpable parathyroid adenoma being the secondary cause of treatment-resistant hypertension. ER -
