Elastofibroma dorsi: A report on 6 cases.

Elastofibromas are slow growing fibroblastic proliferations, which occur mainly in elderly women. They are typically located in the right subscapular region and are usually asymptomatic. The characteristic findings in ultrasonography, computed tomography and magnetic resonance imaging usually allow to make the diagnosis. We report six cases of elastofibroma dorsi, the clinical presentation and radiology findings are reviewed and compared with literature.

Cervical spondylolysis: a case report.

Cervical spondylolysis is defined as a corticated cleft between the superior and inferior articular facets of the articular pillar, the cervical equivalent of the pars interarticularis in the lumbar spine. Of primary importance is its recognition to avoid confusion with more clinically significant abnormalities such as fracture or dislocation. This case report describes bilateral spondylolysis and associated dysplasia of C5 in a 31-year-old female. We describe the radiographic presentation of this anomaly, stressing the importance of computed tomography for correct diagnosis. A review of the literature on this interesting abnormality and a complete differential diagnosis are presented.

[The place of MRI in the hepatic tumors].

MRI semeiology of hepatic tumors was assessed with a retrospective study of 132 patients explored between May 1998 and December 2001. MR examinations were acquired with a one Tesla operating system. All images were acquired by a T2-weighted fast spin echo MR and dynamic flash MR with Gadolinium. Hemangiomas demonstrate characteristic signs in most cases, as was described in the literature. However, adenoma, hepatocellular carcinoma and metastases have various and less specific features.

[Imaging of neuro-Behcet].

Behcet's disease is a vasculitis affecting predominantly the venous system. It's characterized by a classical triad of recurrent uveitis, oral and genital ulceration. Behcet's disease is more frequent in Japan, the Middle East and some Mediterranean countries. Its pathogenesis is still uncertain. Neurological manifestations in Behcet's disease are not rare and are associated with poor prognosis. These manifestations can be inaugural in 5% of cases and they are polymorphous. We report 15 new cases of neuro Behcet's disease explored by magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA).

[Imaging cardiac hydatid cysts: 8 cases].

BACKGROUND: Early diagnosis of cardiac echinococcosis is required because this uncommon disease may lead to serious complications. We report 8 cases of cardiac hydatidosis, review the modes of diagnosis, and stress the contribution of modern imaging techniques. METHODS: This retrospective study describes 8 patients with cardiac echinococcosis. All had chest radiographs and thoracic computed tomography (CT). Transthoracic sonography was performed in 6 cases and magnetic resonance imaging (MRI) in 5. RESULTS: Our patients ranged in age from 7 to 46 years, and the clinical features of their disease varied. Chest radiography showed the contours of the heart to be deformed in 3 cases and cardiomegaly in 3 others. Echocardiography revealed a homogeneous unilocular hydatid cyst in 5 cases. CT found homogeneous hypodense unilocular lesions in 7 cases, and a septated cyst with cardiac wall calcifications in one case. MRI showed round homogeneous lesions in 3 cases, all dark in T1-weighted sequences and bright in T2. DISCUSSION: Clinical features vary substantially, and clinical latency is not uncommon. Chest radiography generally shows mediastinal masses. Transthoracic echocardiography can locate and count cardiac hydatid cysts and identify their borders. CT can simultaneously assess any visceral extension of the disease, while MRI provides details of mediastinal extensions. CONCLUSION: Transthoracic echocardiography suggests the initial diagnosis. CT and MRI provide details of the location and extension of the cardiac hydatidosis.

Primary leiomyosarcoma of bone: report of 4 cases.

Primary leiomyosarcoma of bone is a very rare tumor. Four cases are reported: 3 tumors were located in the femur and 1 in the talus. Clinical and imaging findings including radiographs, CT, and MRI are described. The final diagnosis was made by histopathological, immunohistochemical, and/or ultrastructural study after biopsy.
