Schwannoma: An uncommon dweller in the adrenal gland.

An elderly adult woman presented with upper abdominal pain to the urology department. Imaging studies revealed a right adrenal lesion with central necrosis, abutting the large vessels and suggestive of malignancy. Histopathology showed an encapsulated spindle cell tumor with marked nuclear atypia, cystic change, and hemorrhage. S100 immunomarker was strongly and diffusely positive. Final diagnosis was ancient schwannoma with secondary change. Schwannomas are rare in the adrenal gland, with <50 cases reported in the literature. These incidentally detected nonfunctional adrenal tumors need confirmation with histopathology and ancillary studies.

Childhood adrenoleukodystrophy - Classic and variant - Review of clinical manifestations and magnetic resonance imaging.

Adrenoleukodystrophy (ALD) is a genetic disease associated with demyelination of the central nervous system, adrenal insufficiency, and accumulation of very long-chain fatty acids in tissue and body fluids. The attempt of this paper is to review the classical and not-so-classical MR imaging manifestations of adrenoleukodystrophy. A review of literature is done to describe the pathophysiology of the disease and the imaging differences between childhood and adult-onset of the disease. The literature is reviewed to explain the link with Addison's disease. In consensus the magnetic resonance imaging (MRI) findings of symmetrical occipital white matter lesions which progress in a rostro-caudal direction is the classical appearance of ALD. Familiarity with the clinico-pathologic manifestations and progressive MR imaging features of childhood cerebral X-linked ALD will be helpful in evaluating the affected patients.
