[Vertebral hydatidosis [Report of 22 cases]]

Hydatidosis affects the bone in 0.5 to 2% of cases, with 44% of these cases involving the spine. To describe the radiological characteristics of spinal hydrated. This retrospective study about 22 patients [14 men and 8 women] aged between 10 and 63 years old. The mean age was 29 years, they were explored by conventional explorations in 22 cases, myelography in 12 cases, computed tomography in 15 cases and magnetic resonance imaging in 3 cases. Imagning showed multicystic bony lesions. Thoracic involvement was present in 13 cases, lumbar involvement in 5 cases, cervical in 2 cases and sacral involvement in 2 cases. The process involved 2 adjacent vertebrae in 4 cases, 3 adjacent vertebrae in 5 cases, 4 adjacent vertebrae in 2 cases and the entite sacrum in 2 cases. Vertebral collapse was noted in 3 cases. The extension into the spinal canal was noted in 5 cases. Other sites of involvement were also noted, especially in liver and spleen. The presence of multicystic vertebral lesions with involvement adjacent soft tissues should raise the possibility of spinal hydatidosis in endemic countries

Colloid cyst of the third ventricle

The colloid cyst of the 3rd ventricle is a rare tumor [1% of the intracranial tumors]. It is a benign tumor of the young adult. The definite diagnosis is radiologic particularly. The curative treatment is above all surgical. We report 3 cases of colloid cyst explored by computerized tomography [3 cases]. The mean age of the patients is 22.5 years old [6-35 years old], with a sex-ratio equal to 2. The signs of intracranial high blood pressure have been the mode of discovery in the 3 cases. The definite diagnosis has been based on the cerebral computerized tomography, realized in the 3 cases before and after injection by iodized contrast product with axial slices in 3 cases and coronal axial slices in 2 cases. It visualized round and well limited mass localized in the anterosuperior part of the 3rd ventricle that measured respectively 1.1; 1.5 and 2.5 cm. This mass is spontaneously hyperdense [about 60 UH], not modified after the injection of the contrast product. It is the cause of biventricular hydrocephalus in the 3 cases. The palliative treatment consisted in a ventriclo-peritoneal derivation in the 3 patients. Any patient underwent the cyst ablation. They are still coming for medical advice. The colloid cyst of the 3rd ventricle is a pathology that benefitted from the imaging progresses particularly the computerized tomography and the imaging by magnetic reasonance. Indeed, the radiology permits not only to arrive at the definite diagnosis of the colloid cyst, but also to orientate the therapeutic procedure when it is about stereotaxic aspiration

Malignant peritoneal Schwannoma

We report too cases of malignant Schwannoma of serous membrane. There is an exceptional localization. The clinical and radiological presentations are non specific. The diagnosis was established by histological study. The clinical, radiological presentations and differential diagnosis are discussed

Le cavernoma portal: apport de la T.D.M. A propose d'un cas

The imaging of portal cavernoma is easy. However the flow modifications in hepatic parenchyma may set the differential diagnosis with an infiltrative tumor of the liver. The authors report the case of a portal cavernoma in order to highlight the CT features of hepatic parenchymography in the course of cavernous development

[Wrist arthrography in ligamentous tears of carpal bone. About 10 cases]

The authors report the results of a serie of 10 wrist arthrography, they emphasize the interest of this examination to study the ligamentous systeme of carpal bone, in pretherapeutic evaluation of chronic wrist pean post traumatic wrist and carpal instability

[Rotator cuff injury: the arthrographic aspect]

The authors report on the results of a series of 18 arthrographies of the shoulder realized in patients presenting clinical signs of rotator cuff tear; they emphasize the interest of this examination for the diagnosis and pretherapeutic evaluation of rotator cuff tear

Biliary digestive fistulas. About 31 cases

We report a serie of 31 bilio-digestive fistulae of lithiasis origin. Symptomatologia is often quite atypic. This discovery was fotuitous in 93.6%. Hence, plain X ray examination of the abdomen, and upper gastroduodenal series are of importtance. All our patients have been treated surgically with satisfactory results except one death

Hydatid cyst of the pancreas. About 2 cases

The authors report two cases of pancreatic hydatid cyst and the rarety of this localisation and the poly-morphison of the clinic symptomatology. Attention is drawn to the place of the ultrasonography and the therapeutic problems
