[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.

[Esophageal duplications: role of computed tomography. Apropos of 2 cases]

The authors present two cases of oesophageal duplication: tubular in one case and cystic in the other. This rare anomaly was identified in both cases by CT scan. A review of literature is proposed.

[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.

[Tumor of the bone palate in tertiary syphilis. Contribution of x-ray computed tomography]

The authors report the case of two patients presenting with increased bone density and lytic lesions of the skull due to tertiary syphilis. A malignant tumor has late developed on these lesions. Only one patient was imaged with CT Scan which was very useful to determine the tumoral extension.

[Small intestine occlusion caused by the silent opening of liver hydatid cysts into the peritoneum. Apropos of an uncommon case]

The authors report one exceptional case of organic small bowel occlusion. The etiological diagnosis was performed by ultrasonographic examination and showed two hydatid cysts of the liver opened into the peritoneum and a peritoneal fluid collection corresponding to the hydatid fluid. The authors emphasize the absence of clinical symptoms during the opening of the hydatid cysts of the liver into the peritoneum and the usefulness of emergency ultrasonographic examination of the entire abdomen in cases of small bowel obstruction without any evident etiology.

[Teratoma of the parotid region: an uncommon disease. Apropos of a case with review of the literature]

Cervicofacial teratoma is an infrequently reported tumor that is usually diagnosed at birth and is very rarely seen after one year of age. In the case reported, an exceptional finding was a teratoma of the parotid region in an adolescent. A literature review underlines the rarity of the lesion, diagnosis being assisted by radiologic and CT scan imaging.
