ABSTRACT
A case of heterotopic gastric mucosa in discrete nodules of the duodenum is presented. Its radiographic and endoscopic appearance is described. The light and electron microscopic features are analyzed. Ultrastructural examination of its organization, cellular and subcellular components revealed similarities to normal fundic gastric mucosa. The histological and clinical differences between heterotopic gastric mucosa and duodenal metaplastic change are discussed.

Common varieties of muscular dystrophy rarely involve the extraocular muscles, but several uncommon varieties do. In one of our patients with ocular muscular dystrophy (Von Graefe's disease), computed tomography demonstrated atrophy of the extraocular muscles, particularly of the lateral rectus muscles. Involvement of the extraocular muscles by muscular dystrophy has not been previously reported or demonstrated in the radiological literature.
