Pheochromocytoma as a rare cause of arterial hypertension in a patient with autosomal dominant polycystic kidney disease: A diagnostic and therapeutic dilemma.

# metadata.dc.description.abstract[].value
INTRODUCTION: Individuals with autosomal dominant polycystic kidney disease (ADPKD) frequently suffer arterial hypertension even prior to significant loss of renal function, a clinical situation that obscures detection of modifiable secondary causes of hypertension. PRESENTATION OF CASE: A 50-year-old man with ADPKD and polycystic liver and resistant hypertension is diagnosed with a 4-cm right adrenal mass. Cross-sectional MRI is indicative of pheochromocytoma versus adrenocortical carcinoma or metastasis, though there are no typical PCC symptoms and plasma and urine metanephrines are within normal ranges. Since malignancy cannot be excluded, right adrenalectomy is performed. Considering that the enlarged liver poses an obstacle for transperitoneal open and laparoscopic approaches, a retroperitoneoscopic approach is used. Surgical pathology reveals a 4.5-cm pheochromocytoma; the patient no longer requires antihypertensive therapy. DISCUSSION & CONCLUSION: Pheochromocytoma is a rare but treatable cause of hypertension in ADPKD; given the anatomical complexities these patients present, careful preoperative planning and surgical technique are essential to a favorable outcome.
