[Changes in the cranio-cervical junction in Down's syndrome].

Twenty-eight subjects with Down syndrome, 9-29 years old, were examined for instability of the cervical spine at the atlanto-axial and atlanto-occipital joints. This region was studied by evaluating the atlanto-odontoid space and the basilar line both in neutral position and during functional movements. Two patients (7.2%) presented atlanto-axial anomalies, while 3 patients (10.7%) showed atlanto-occipital instability. Clinical goniometric measurements demonstrated specific and significant improvement in the extension movement of Down patients, when compared to the control group.

[Computerized tomography in rheumatoid arthritis of the cranio-cervical junction].

Twenty rheumatoid arthritis (RA) patients with involvement of the cranio-cervical junction (CCJ) were given CT scan. In most cases the myelo-CT technique with the lumbar injection of small quantities of non-ionic contrast medium was adopted; CT easily diagnosed the "horizontal" and "vertical" dislocations on the CCJ, the bone structure lesions and the inflammatory masses. A high frequency of medullary compressions was also found in these patients. Myelo-CT appears to be the technique of choice for the precise definition of the various factors responsible for the neurological complications found in RA of the CCJ.

[The role of Doppler US in the study of carotid system].

Color Doppler US is at present the most reliable noninvasive procedure in the diagnosis of carotid disease and plays a major diagnostic role in the patient at risk for stroke. The anatomofunctional relationships of carotid and vertebrobasilar system suggest a diagnostic combination between Doppler US and transcranial Doppler for complete hemodynamic evaluation of normal and pathologic cerebral vessels. The most relevant disease, as the cause of stroke, is represented by internal carotid atherosclerosis. Mechanisms by which the atheromatous plaque represents a cause of ischemia involve two factors: the embolic factor and the hemodynamic factor. The embolic factor is consequent on unstable plaques and US plays a major role in plaque characterization. Stenotic plaques are the major cause of the hemodynamic factor. Color Doppler US inables quantification of stenosis and selects surgical patients with greater than 70% stenosis. In internal carotid dissection as the acute cause of cerebrovascular insufficiency color Doppler US findings are significant for early diagnosis and follow-up.

Diagnostic imaging of neurotuberculosis.

Neurotuberculosis is represented by different and possibly concomitant forms, of which the most frequent are tuberculous meningitis and parenchymal tuberculosis followed by cerebral miliary tuberculosis and the extremely rare tuberculous abscesses. Tuberculous meningitis is characterized by the presence of inflammatory meningeal exudate involving meningeal surfaces and CSF spaces with involvement of relative vascular and nervous structures. Most frequent complications are parenchymal infarction, hydrocephalus and mycotic aneurysms. Inflammatory meningeal exudate shows intense contrast enhancement. Parenchymal tuberculosis may directly involve the cerebral and/or medullary parenchyma as areas of cerebritis/myelitis with solid nodular lesions (tuberculomas) with a central area of caseating necrosis. Tuberculomas are characterized by intense nodular or ring enhancement.
