A rare case of giant adrenal ganglioneuroma

Abstract

Ganglioneuromas (GN) are rare benign tumors that typically occur in the posterior mediastinum or retroperitoneal region, but can also be found in adrenal glands. Up to 50% of patients are asymptomatic, but symptoms can arise from the mass effect or excessive secretion of catecholamines. Careful evaluation is necessary to differentiate GNs from other adrenal tumors. A 19-year-old female patient with no previous comorbidities was diagnosed with a right adrenal incidentaloma. Physical examination and routine laboratory tests were normal. Imaging revealed a solid lesion in the right adrenal gland, and excisional adrenalectomy was performed. Pathological examination confirmed the diagnosis of a right adrenal GN. The patient had an uneventful recovery and showed no recurrence during the follow-up period. Conclusion: After surgical removal of a benign neurogenic tumor, our patient had no tumor recurrence after five months, indicating a positive prognosis. However, long-term follow-up is still recommended because of reported cases of metastases and recurrence in some patients.
