Emangioma del ginocchio
No full textIntra-articular, or vascular hamartoma, is a tumor-like lesion assentially made up of anomalous blood vessels localized in the joint capsule, in the synovial membrane, or in both structures. There are two anatomical varieties: one circumscribed localised and one extended. There seeems to be predilection for the female sex, and age of onset ranges from birdth to 20-30 years of age; it occurs more frequently in the knee, less in the elbow, in the wrist and in the ankle. Synptoms, which often begin after local trauma, include joint swelling nd pain, both characterized by discontinuity anf long duration. sometimes there is an increase in swelling, repeated episodes of hemarthrosis, forced position and functional of the joint, increase in skin temperature. Final diagnosis can only be obtained with histological exam, although MRI may be useful and arteriography clearly reveals it, if the hamartoma is extended enough and communicating with the circulation. Histological exam carried out on fragments of tissue taken in loco receals a labyrinthine agglomerate of fissures and lengthening cavities, with walls that are generally thick and of a venous-like anomalous type. The course of the desease is slow, with pediods of remission of local symptoms of varying duration.Treatment is surgical and it consist in complete removal when possible of the angiomas. The results are satisfactory; recurrence is infrequent and it is generally due to incomplete excision of the noeformation

Full text linkGoal of the study. The purpose of this study is to compare the accuracy of sonographic to radiographic measurements of subacromial space, and verify its variations in relation to acromial morphology, age, sex and rotator cuff pathologies. Materials and methods. As a result, we have compared a radiographic examination to sonographic examination, each measuring the subacromial space in 200 random shoulders, with a personal method. The sonographic examination was performed by using a HDI 5000 ultrasound scanner Sono-CT with 7.5 MHz linear array transducer. No stand-off pad was utilized. Results. The statistical analysis of the data derived from the two measurements was not sufficient to conclude that the two techniques are different (p>0.8). They also correspond with the radiographic morphology of the acromion. The size of subacromial space was related to the acromial morphology, female gender, and rotator cuff pathology, however, it was not related to age. Discussion and conclusions. Our results clearly show that sonographic measurements are very close to those obtained by X-ray (p>0.8). The Bland–Altman analysis showed that for all groups, the were small enough to give us confidence that the sonographic technique may be used in place of the radiographic one for clinical purposes. One-way ANOVA showed that sonographic measurements were statistically different among the four groups (p<0.05). The sonography demonstrated precision, accuracy and carefulness in the measurement of the subacromial space
