The authors report a case of chronic post-traumatic dissecting aneurysm associated with myocardial contusion in a 13 year old adolescent. They stress the rarity of this condition in children and discuss the diagnostic contribution of various imaging techniques.
Posterior pre-marginal disk hernia, a rare lesion, was diagnosed in six young adults with lumbago. Lateral lumbar spine radiographic images showed an unusual appearance, combining a posterior marginal defect of a vertebral corner and a small bony spicule projecting into lumbar canal. A literature review revealed 27 similar cases, mostly in adolescents. These vertebral disk anomalies are considered by some authors to be fractures of the posterior margin border. A more plausible hypothesis is a pre-marginal hernia, because of lack of a history of injury, the radiologic appearance comparable with that of sequelae of Scheuermann's disease, and the frequent association of these lesions with a spinal growth dystrophy.
Ten cases of Behçet's disease with arterial lesions were observed in a series of 500 patients over a period of 12 years. The majority of patients were male (9/10) aged between 24 and 36 years with a mean of 30 +/- 5 years. The first group (3 cases) presented with thrombosis of the radial and superficial femoral arteries, the second group (4 cases) presented with aneurysm of the subclavian artery, common and external iliac arteries, brachiocephalic trunk and abdominal aorta and the third group (3 cases) had a combination of thrombosis and aneurysm of the pulmonary, external iliac and renal arteries.

The authors report the case of a 31-year old woman who was operated upon for cervical bone tumour. The pathological study showed that it was a primary, highly differentiated osteosarcoma. The clinical picture was limited to a spinal cord compression syndrome without signs of inflammation. Radiological findings were non-specific. Treatment consisted of laminectomy, radiotherapy and chemotherapy. The course of the disease was marked by stabilization, then rapid aggravation 2 years after the operation. A review of the literature highlighted the rarity and relatively slow progression of primary osteosarcomas of the spine.
Lesions of seminal vesicles during urogenital schistosomiasis are a frequent finding but their manifestation as a palpable mass is a rare feature. An exceptional case of a large schistosomial spermatocyst is reported in which diagnosis was by histopathology.

In a retrospective study, the authors report 14 cases of osteoarticular manifestations, among 29 patients affected with a sickle cell disease observed at adult age. They insist on their frequency and their interest for diagnosis and prognostic. Effectively, the diagnosis has been revealed on occasion of these manifestations in 9 cases/14. The articular signs are noted in 35%, and the osseous signs in 25% of cases.

The very rare portal vein calcifictions are detected in patients with a portal hypertension syndrome (PHT). A patient with hepatosplenomegaly and mild signs of PHT presented images of parietal calcifications, and the diagnostic values of different imaging techniques, particularly ultrasound and CT scan, are compared.
