Simultaneous occurrence of primary aldosteronism due to aldosteronoma and ectopic meningioma in the adrenal gland: A case report

RATIONALE: Primary aldosteronism due to aldosteronoma is the most common form of secondary hypertension, with an estimated prevalence of 4% of hypertensive patients in primary care and around 10% of referred patients. Diagnosis is a clinical challenge with simultaneous occurrence of primary ectopic meningioma in the adrenal gland. To our knowledge this is the first reported case of simultaneous occurrence of aldosteronomas and ectopic meningioma in the adrenal gland based on literatures. PATIENT CONCERNS: A 30-year-old man presented with resistant hypertension for one year. The computed tomographic scans were suggestive of left adrenal gland hyperplasia. INTERVENTION: The patient underwent partial unilateral laparoscopic adrenalectomy. DIAGNOSIS: The histopathological examination of the resected sample confirmed primary ectopic meningioma in adrenal gland and aldosterone producing adenoma (APA). The saline load test, captopril test, and plasma aldosterone/renin ratio were indicative of primary aldosteronism (PA). OUTCOMES: The patient had controlled blood pressure postoperatively. LESSONS: The patient was diagnosed with PA due to APA and nonfunctional primary ectopic meningioma in the adrenal gland which is very rare and dealt with unilateral laparoscopic adrenalectomy.
