ABSTRACT
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.

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.

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.

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.

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.

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.

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.
