Abstract
Schwannomas, which are benign mesenchymal tumors derived from Schwann cells, are common in the central nervous system. While they are commonly seen in the extremities and head-neck area, their presence in visceral organs, particularly the adrenals, is uncommon. Adrenal schwannomas are frequently discovered incidentally, offering a diagnostic difficulty because of their uncommon presentation. A 46-year-old woman initially sought treatment for symptoms related to uterine fibroids and biliary stones. Diagnostic imaging uncovered an adrenal incidentaloma, necessitating a laparoscopic right adrenalectomy. The mass was determined to be an adrenal schwannoma based on its spindle-shaped cells and S-100 immunohistochemistry positivity. The patient's symptoms improved, and she was discharged with stable vital signs. Preoperative diagnosis of adrenal schwannomas is difficult and requires histological confirmation. When diagnosing non-secreting adrenal tumors with unusual radiology, surgeons should investigate for schwannoma. Post-resection adrenal schwannoma follow-up studies are scarce; however, they imply a low risk of recurrence or metastasis.
