[Mediterranean lymphoma mimicking Crohn's disease].

We report an uncommon localization of mediterranean lymphoma of the terminal ileum in a 28 year-old male patient. Ultrasound and Computed Tomography showed moderate regular and symmetrical intestinal wall thickening simulating Crohn's disease. We highlight the role of computed tomography in the diagnosis, staging and detection of complications.

[Splenic nodules and sickle cell anemia].

OBJECTIVE: We report 4 patients with sickle cell anemia presenting with intra-splenic benign nodules corresponding to islands of preserved tissue within splenic ferro-calcinosis. MATERIAL AND METHODS: Ultrasound, CT and MRI findings were evaluated and compared to a follow-up study by ultrasound and CT done after 6 to 12 months. RESULTS: Ultrasound showed multiple well-defined rounded nodules appearing hypoechoic compared to the rest of the spleen that was hyperechoic. On CT, the nodules were homogenous, hypodense relative to the spleen, isodense to the liver in 3 cases and hypodense to the liver in 1 case. On MRI, the nodules appeared relatively hyperintense within low-signal-intensity spleens. The ultrasound and CT follow-up study demonstrated no remarkable change. CONCLUSION: In sickle cell patients, intra-splenic benign nodules corresponding to normal splenic tissue may be identified on imaging studies. The differential diagnosis is discussed.

[Therapeutic ligature of hypogastric arteries: color Doppler follow-up].

PURPOSE: To evaluate the interest of color Doppler sonography in the watching of therapeutic ligature of hypogastric arteries. PATIENTS AND METHODS: Thirteen female patients presenting a serious haemorrhage in the post-partum and be in managed by bilateral hypogastric ligature, have undergone a systematic protocol of investigation involving a Doppler sonography in the fourth day after intervention and then monthly until repermeabilization of the internal iliac arteries. RESULTS: In all cases, the first exam showed down-side the ligature, a flow inversion with an important pelvic collateral circulation. The next Doppler exams showed repermeabilization of the hypogastric arteries after an average interval of 5 months (extremes: 1 to 6 months). CONCLUSION: Color Doppler showed the resolvent character of therapeutic ligature of the hypogastric arteries and may estimate with sufficient accuracy the interval of repermeabilization.

[Diagnosis of an opacity at the lung base: intrathoracic kidney].

A 72-year-old patient was admitted for exploration of an opacity of the left base discovered fortuitously on a routine chest x-ray. Initial blood tests were normal. Fiberoptic bronchoscopy was normal. Computed tomography (CT) led to the diagnosis of a left kidney which had risen into a retro-cardiac position. Magnetic resonance imaging established the sub-diaphragmatic position of the kidney. Renal excretion was normal on intravenous urography. An ectopic kidney in an intrathoracic position is very uncommon and may raise a major challenge when visualized as a mediastinal or pulmonary opacity. Computed tomography or intravenous urography can provide the diagnosis and magnetic resonance imaging demonstrates its precise sub-diaphragmatic or supra-diaphragmatic position.

[Post hydatid chronic cor pulmonale].

We report a case in a patient aged 28 admitted with haemoptysis and dyspnoea. The chest x-ray showed multiple disseminated hydatid cysts throughout the lung fields. Computerized tomography and an abdominal echo found a hydatid cyst of the liver in contact with inferior vena cava which was probably responsible for the secondary pulmonary dissemination. Subsequently there was a multiplication of the lesions with rupture and infection of several cysts. After two years the disease progressed into chronic respiratory failure with the appearance of chronic cor pulmonale. The respiratory state rapidly worsened with several episodes of cardiorespiratory failure. Death occurred six months after the appearance of CPC.

[Value of ultrasonics in differential diagnosis of pseudotumor hydatid cyst of the liver and other solid hepatic masses (prospective study)].

A prospective study in 88 consecutive patients with solid hepatic mass was performed to determine the value of ultrasound in the diagnosis of pseudo-tumoral hydatid cyst. Ultrasonography systematically searched 5 evocative signs: hypoechoic spiral, peripheric hypoechoic rim surrounded by an echoic border, daughter cysts, hyperechoic areas with shadowing and/or enhancement of back-wall echos. Diagnosis of pseudo-tumoral hydatid cyst was based upon the association of, at least, 2 signs. The sensitivity of echography was 92.3% and the specificity was 98.3%. Furthermore this study allow us to propose a new, more accurate, definition of the hydatid spiral. However, serologic tests were found to be of little interest.

[Pseudotumoral abdominal cysto-steato-necrosis: an unusual etiology].

We report an unusual case of subcutaneous pseudo-neoplastic focal fat necrosis in a woman with a Mersilen plate placed outside the abdominal wall muscles. To our knowledge, this association has not been previously reported in the radiologic literature. The differential diagnosis using ultrasound and computerized tomography is discussed.

[Spontaneous cerebrospinal rhinorrhea: role of computerized opaque cisternography].

Spontaneous CSF rhinorrhoea, secondary to trauma in the great majority of cases, is very rare (3-4%). The authors report a case of spontaneous CSF rhinorrhoea secondary to an ethmoidal osteodural defect, diagnosed by digital cisternography and confirmed by the surgical operation. The value of digital opaque cisternography and its place in the diagnostic arsenal are discussed.

Magnetic resonance angiography (MRA) of the circle of Willis: a prospective comparison with conventional angiography in 54 subjects.

We prospectively correlated the findings of magnetic resonance angiography (MRA) with those of transfemoral four-vessel angiography in 54 patients to investigate the direction of flow within the circle of Willis. Our primary goal was to assess the direction of flow using the size of the vessel and signal intensity, without saturation techniques. Analysis of the circle of Willis, especially the communicating arteries, was performed double-blind by two groups of two radiologists. Three types of arteries were identified: high flow or cross-cerebral circulation, patent and nonvisualised arteries. Cerebral angiography was the standard for comparison between the two methods. MRA did not reveal any arteries invisible on angiography, thus providing a specificity of 100%. The sensitivity of MRA was 89.2% for the anterior and 81.3% for the posterior communicating arteries, and 100% for the anterior, middle and posterior cerebral arteries. MRA was shown to be a useful technique for the assessment of patency of the circle of Willis.

[Measurement of the obstetrical pelvis by tomodensitometry (110 cases)].

We had studied in one year 110 cases of scano-pelvimetry, the clinical examination had not found a shrink pound in 41%, revealed by the sceno-pelvimetry. This method is more precisely than the classic pelvimetry, but more expansive. The simultaneous study of echography and pelvimetry had contributed to a better obstetrical decision.

[Celiac plexus block: value of x-ray computed guidance].

Celiac plexus block is a good alternative of pain treatment in upper abdominal pain. Neurolysis of the celiac plexus by the percutaneous posterior route used CT guidance in 8 patients. Pain relief was obtained in 5 of 7 patients (70 per cent); no complication occurred.
