ABSTRACT

Adrenal schwannomas are very rare tumors. They originate from the myelin sheath of the nerves in the adrenal medulla. While adrenal schwannomas can rarely cause some clinical symptoms, such as abdominal pain and back pain, most of them present as a nonsecretory adrenal mass in an asymptomatic patient. We here in report a 41-year-old male who was referred to our endocrinology outpatient clinic due to an adrenal mass detected on abdominal ultrasound during evaluation of abdominal pain. Triphasic computed tomography of the abdomen demonstrated a 29x26 mm right adrenal mass with a density of 24 HU which did not show washout. Hormonal work-up revealed that adrenal tumor was nonsecretory. Since the radiological characteristics of the lesion were suspicious for a malignant tumor, the patient underwent right adrenalectomy, and the pathological examination demonstrated adrenal schwannoma.
