[Craniopharyngioma with intraventricular development. Apropos of 2 cases. X-ray computed tomographic aspect]. / Craniopharyngiomes à développement intra-ventriculaire. A propos de deux observations. Aspect tomodensitométrique.

We report two cases of craniopharyngioma developed within the third ventricle. In this occasion we present the different C. T. findings of these tumors.

[Spondylodiscitis after embolization of an extramedullary intraspinal arteriovenous fistula]. / Spondylodiscite après embolisation d'une fistule artérioveineuse intra-canalaire extra-médullaire.

The authors report a case of spondylitis Th11-Th12 occurred 1 month after embolization of an intraspinal extramedullary arteriovenous fistulae; this fistulae was fed by 11th left intercostal artery. The infecting organism isolated from the affected intervertebral disc was streptococcus sanguis a common agent of dental abscess.

[Diagnosis of ivory vertebra. Bibliographic study, report of 2 cases of pagetic ivory vertebra]. / Diagnostic d'une vertèbre d'ivoire. Etude bibliographique, rapport de 2 cas de vertèbre d'ivoire pagétique.

Two cases are reported of ivory vertebra, an isolated lesion difficult to diagnose clinically or radiologically. Tomographic and if necessary computed tomographic analysis should provide a precise diagnosis of a Paget's disease origin, biopsy being reserved for cases for which a doubt exists.

[Dense intracerebral cholesteatoma in computed x-ray tomography. Apropos of a case]. / Cholestéatome intra-cérébral hyperdense en tomodensitométrie. A propos d'un case.

The authors report a case of cholesteatoma which is uncommon on account of its dense appearance on the C.T. scan and its temporal localization.

[Dorsal spinal cord compression caused by vertebral subperiosteal chondroma. Apropos of 2 cases]. / Compression médullaire dorsale par chondrome sous-périosté vertébral. A propos de 2 observations.

The authors report 2 cases of vertebral subperiosteal chondroma causing thoracic spinal cord compression. Total excision of this benign cartilaginous neoplasm is usually sufficient treatment.

[Subperiosteal chondroma. Diagnostic contribution of x-ray computed tomography. Apropos of 2 cases]. / Chondrome sous-périosté. Contribution diagnostique de la tomodensitométrie. A propos de 2 observations.

Results of CT scan exploration are reported in two cases of subperiosteal chondroma, one in a 4 year old child affecting the anterior tibial tuberosity the other in a 9 year old child involving the upper end of humerus. Data from CT scan imaging were undoubtedly superior to those of conventional radiography and appear to be characteristic of this benign cartilaginous tumor, greatly facilitating correlation between clinical, radiological and pathologic findings. The scanner should allow certain situations to be dedramatized and the surgical attitude adapted when the functional prognosis is involved.

[Enthesopathy of the upper insertion of the musculus rectus femoris. A retrospective sign of tendon rupture in sports pathology]. / Enthésopathie de l'insertion haute du droit antérieur. Un signe rétrospectif de rupture tendineuse en pathologie sportive.

We report 4 cases of post-traumatic enthesopathy occurring later after rupture of rectus femoris tendon from the anterior superior iliac spine. Radiographic feature and clinical picture are typical of diagnosis.

[Bilateral traumatic carotid-cavernous fistula treated using an inflatable and detachable balloon]. / Fistule carotido-caverneuse traumatique bilatérale traitée par ballonnet gonflable et largable.

The authors report a case of traumatic bilateral carotid-cavernous fistula successfully treated by inflatable and detachable balloon.

[Synovial cysts of unusual localization. 2 cases and review of the literature]. / Kystes synoviaux de topographie inhabituelle. Deux observations et revue de la littérature.

Two patients with true synovial cysts in atypical sites (internal compartment of knee and inguinal hollow) were investigated by radioarthrography, ultrasound and computed tomography imaging. The cyst in the hip region originated from a dilated serous bursa of the iliopsoas muscle that did not communicate or was no longer in communication with the joint. In contrast, the cyst of the knee appeared to be a lateral synovial capsule hernia. Positive diagnosis in both cases was dependent on combined ultrasound-CT scan imaging, this eliminating a tumor (sarcoma) of soft tissues. However, affirmation of the synovial origin (mesothelial covering of the wall) of the lesion was obtained by histology only, this allowing differentiation from a "capsular" (fibrous wall) cyst, which probably provokes similar ultrasound and CT scan images.

[Rupture of an intracerebral dermoid cyst. Apropos of a case: x-ray computed tomographic aspects]. / Rupture d'un kyste dermoïde intra-cérébral. A propos d'une observation: aspect tomodensitométrique.

We report the C.T. findings of a dermoid cyst communicating with ventricular system and ruptured in the subarachnoid space. A fat-fluid level and calcifications were present on the plain skull X rays.
