Percutaneous Aspiration and Sclerotherapy as Primary Management for a Symptomatic Benign Adrenal Cyst

Adrenal cysts are a rare benign adrenal pathology. Although the majority of adrenal cysts are asymptomatic, large cysts may present with debilitating symptoms of mass effect. Surgical adrenalectomy or cyst fenestration has been the primary mode of management for such symptomatic cysts, but these interventions can be associated with excessive morbidity, particularly when considered in the context of benign disease. Here, we present a case of a 34-year-old female with a longstanding, growing, benign left adrenal cyst associated with nonspecific abdominal symptoms. After multidisciplinary discussion, the patient was managed with primary ultrasound/fluoroscopic guided percutaneous sclerotherapy of her adrenal cyst. This technique achieved complete cyst resolution that was durable on 7-month follow-up and was associated with significant improvement of the patient's symptoms. This case illustrates the potential for primary percutaneous sclerotherapy for primary management of benign adrenal cysts.
