ABSTRACT
Three cases of extraosseous Ewing sarcoma are reported. This pathology of the young adult is very rare as shown by the review of the literature. Clinical or imaging (CT or MRI) findings are non-specific and diagnosis is based on histology. Nonetheless, this diagnosis should be considered in all patients with primary soft tissue tumors.

We present a case of symptomatic pneumatocyst of the ilium observed in a professional scuba diver exposed to pressure variations. Pneumatocysts are rare and except for one case reported in a clavicular localization, are always found in subchondral bone of the iliac or sacral side of the sacroiliac joint. Undoubtedly, air fills an intraosseous node. We report here the first case of efficient treatment achieved by filling the cyst via percutaneous access under scopic control.

Authors study retrospectively 81 cases of isolated recent (less than three months) knee traumas. These include clinical aspects, NMR, arthroscopy. Clinical examinations have been graded: 1. possible lesion; 2. likely lesions; 3. confirmed lesions. Clinical examinations and NMR results are compared to arthroscopy considered as reference. Clinical examination of acute traumatic knee is essential. Nevertheless, its value for detecting precise lesions is poor, except for knee locking well correlated with meniscal tears. Results show that NMR provide better results than clinical examination. NMR is reliable for detecting tears of posterior cruciate ligament, tears of posterior horn of menisci (sensibility: 93%; specificity: 80%). Its results are less effective for appreciation of lesion of anterior cruciate ligament (sensibility: 88%; specificity: 78%) because of partial tears and functional but not morphologic damage. It is the only method able to evidence osteochondral injuries and soft-tissues associated lesions in traumatic knees. Emergency NMR scans show results no differences in results compared with routine examinations. However, one should keep in mind that negative NMR cannot exclude small cartilaginous lesions and partial tears of anterior cruciate ligament. According to these results and the known qualities of NMR (non invasive), we propose that this type of investigation should be more largely included in diagnostic attitude for acute injured knee. Emergency diagnostic arthroscopy could be efficiently replaced by NMR knee examination.

Often mentioned and not much documented, the lipoblastic meningioma is an unusual extra-axial benign tumor. It has spontaneously hypodensity in CT and appears with a high signal in MRI in T1-weighted sequence. Its vascularisation is rich and shows a strong contrast intake. Its resection is known as easy and its prognosis is excellent. The authors report here the observation of a 65 year old women having a lipoblastic meningioma. Literature is gone through and differential diagnoses are considered.

A case of spinal extramedullary cysticercosis with location in basal cisterns is reported. It was revealed by a severe sciatalgia and studied with MR imaging which is precious for the diagnosis and the follow-up. Cerebral cisternal arachnoiditis is the main problem in this racemose form where long medical treatment is necessary.

A case of an adult intussusception secondary to a fibroid polyp of the terminal ileum is reported. Adult intussusceptions are observed rarely, usually caused by an organic lesion. The preoperative diagnosis is based on US patterns, target aspect and sandwich sign.

Fat is a fundamental contrast agent in pelvic imaging. The features of fat are typical on CT and MRI but vary on ultrasonography according to the physical characteristics and histology. The study of pelvic fat is of great importance in pelvic exploration because fat outlines both the normal structures and their borders. Involvement or masking of the pelvic fat is a good marker of carcinologic spread. Changes in pelvic fat may also be observe in inflammatory diseases. Specific diseases of fatty pelvic connective tissue such as lipomatosis and liposarcomas, are classically described. Teratomas with a fatty component derived from pelvic structures (ovaries) are easily diagnosed using imaging methods.

The review embraces major trends and tendencies in liposome studies and is based on the statistical and qualitative analysis of patent information issued in the period 1970-1988. Special attention is devoted to the analysis of patents in liposome production techniques, their lipid composition, and application in pharmaceutical and cosmetic industries and also for the diagnostic and therapeutic purposes. Liposomal preparations are shown to be superior to common drugs as concerns, in particular, liposomes containing medicinal agents for prolonged use (including hormones, antibiotics, cytostatics, and immunostimulants) and liposomes used in dermatological practice. Liposome-based assessment of application prospects is given.
