RESUMO
A 55-year-old woman with primary (granulomatous) angiitis of the central nervous system in association with non-Hodgkin's lymphoma (mucosa-associated lymphoid tissue type) presented with an acute spinal subdural hemorrhage secondary to rupture of one of several fusiform inflammatory aneurysms of the spinal cord radicular arteries. The literature on hemorrhagic complications, aneurysms, and spinal cord involvement in granulomatous angiitis is reviewed. Recognition of granulomatous angiitis is important, as the condition may be responsive to immunosuppressive therapy.

The double contrast barium meal appearance of four cases is presented where an anomalous peritoneal fold involves the duodenum. This fold results in a characteristic smooth, extrinsic indentation upon the antero-superior surface of the duodenal cap. This normal variant should be differentiated from distortion of this region due to pathology such as peptic ulceration. Anomalous peritoneal folds which involve the duodenum (cystoduodenal ligament, cysto-gastrocolic ligament) are not believed to cause symptoms (1). However, the recognition of the deformity produced by these folds is important, requiring differentiation from pathological changes.

The double contrast barium enema appearances of seven colonic lipomas are reviewed. These lesions have submucosal features: intact mucosa, sharp margination and obtuse angles between the lesion and the adjacent colonic wall, as well as features characteristic of lipomas: pliability and shape change, broad pedicles and spherical appearances en face. They can be differentiated from the more significant colonic adenomas and then CT scanned to establish a histological diagnosis. The need for colonoscopic or surgical excision of these predominantly asymptomatic lesions occurring in elderly patients can be considerably reduced.
