Adrenal schwannoma: a rare type of adrenal incidentaloma.

[adrenal incidentaloma]

Adrenal schwannoma is a rare type of adrenal incidentaloma , an adrenal lesion found incidentally , usually on imaging or autopsy . Computed tomography and magnetic resonance imaging are tools used to evaluate adrenal lesions . The diagnosis of adrenal schwannoma , however , can not be made on imaging alone . Surgical resection is the primary means of management of adrenal schwannomas , as it is not possible to distinguish the schwannoma from malignant entities simply based on imaging . Histopathologic features of adrenal schwannomas are similar to those of schwannomas found at other sites . Conventional schwannomas , consisting of alternating Antoni A and Antoni B areas as well as Verocay bodies , have distinct microscopic features and can be readily distinguished from other entities . Cellular schwannomas , on the other hand , consist only of intersecting fascicles of spindle cells or Antoni A areas , resulting in a wide differential diagnosis . Ancillary studies such as immunohistochemical analysis and electron microscopy can help to provide a specific diagnosis .
