Mesenteric panniculitis: US and CT features.

Mesenteric panniculitis is an aseptic inflammation of mesenteric fat. Before the age of ultrasonography (US) and computed tomography (CT), mesenteric panniculitis was rarely diagnosed, but today the disorder is more commonly encountered, often as an incidental imaging finding. Its exact cause remains unknown. This review illustrates the characteristic US and CT features of mesenteric panniculitis and discusses its differential diagnosis.

Fibrous dysplasia vs adamantinoma of the tibia: differentiation based on discriminant analysis of clinical and plain film findings.

Differentiation between benign fibrous dysplasia and malignant adamantinoma of the tibia is challenging because of the impact the diagnosis has on the choice of treatment (none or extensive surgery). The histologic and pathologic similarities of the lesions and the controversial relationship between fibrous dysplasia, osteofibrous dysplasia, and adamantinoma complicate the matter. We found a large overlap of histologic features in lesions considered either fibrous dysplasia or osteofibrous dysplasia on the basis of the radiologic findings. The purpose of this study was to determine the value of the plain radiograph of the lower leg in combination with clinical findings to differentiate the benign from the malignant condition. The clinical symptoms, radiographs, and histologic slides of 46 patients with fibrous dysplasia and 22 with adamantinoma in the tibia were reviewed retrospectively. In only one of 12 patients with radiologic or histologic characteristics of osteofibrous dysplasia were both radiologic and histologic criteria for the diagnosis present. A linear discriminant analysis was performed on six clinical (age, spontaneous pain, pain after trauma, swelling only, pain and swelling, and bowing deformity) and 25 radiologic signs. Fibrous dysplasia and its variant osteofibrous dysplasia could be identified correctly in 87% (40 of 46 patients) and adamantinoma in 95% (21 of 22 patients) by using the patient's age and four radiologic signs. When results from the discriminant analysis of a randomized subgroup of patients (32) were used on the other subgroup (36 patients), fibrous dysplasia was correctly identified in 84% (21 of 25) and adamantinoma in 82% (nine of 11). Fibrous dysplasia is more prevalent than adamantinoma in a young patient, when radiographs show a ground-glass appearance and anterior bowing and when there is no multilayered periosteal reaction and moth-eaten destruction. When radiologic signs and the patient's age are combined, fibrous dysplasia and adamantinoma can be discriminated in a high percentage of patients.

Graft-versus-host disease of the gastrointestinal tract.

Forty-two gastrointestinal examinations performed in 24 patients with a history of bone marrow transplantation were analyzed retrospectively. All patients were clinically suspected of a graft-versus-host disease (GVHD) involving the alimentary tract. No specific abnormalities were found in the esophagus or the stomach. Radiographic features of a GVHD of the small bowel are: edema of mucosal folds in ileum and jejunum; effacement of folds towards the ileum; thickening of the bowel wall, and spasms and stenosis with prestenotic dilatation. In the active phase the bowel appears to be shortened. A short transit time was not a specific finding. Follow-up examinations showed partial regression of these findings. Radiological findings in the colon consisted of loss of haustration, thumbprinting, spasms and ulcerations.
