Joubert syndrome: a case confirmed by computerized tomography.

The authors report a new case of Joubert syndrome (agenesis of the cerebellar vermis, mental retardation, disturbance of respiratory rhythm, ataxia, abnormal eye-movements) and review the relevant literature on the other nine cases reported. The diagnosis in the present case was confirmed by computerized tomography. Early recognition of this syndrome is important in view of the prognosis and for genetic counseling.

[Nuclear magnetic resonance in pathology of the central nervous system in children].

The following study aims to establish the role of MRI in investigation of the CNS in children. 300 patients are examined, 220 affected by CNS disease. The examinations were performed using SE sequence (T1-weighted images TR = 350-700 ms TE = 30-60 ms; T2-weighted images TR = 1500-2000 ms TE = 50-200 ms). In most of the patients general anesthesia or sedation was necessary. Patients are divided into groups based on pathology and the advantages and shortcomings of MRI are discussed. In conclusion, MRI should be the technique of choice in the evaluation of malformative affections, white matter and inflammatory disease; it should be complementary to CT and angiography in tumors and vascular pathology.

[Intracranial hemorrhage studied with a high-field (1.5T) NMR apparatus].

Fifty-two patients were studied with high-field magnetic resonance imaging (1.5T), with T1- and T2-weighted spin-echo pulse sequences. The study was aimed at assessing the efficacy of MR imaging in the evaluation of intracranial hematomas. Characteristic intensity patterns were observed in the evolution of the hematomas, due to the physicochemical changes in hemoglobin. No acute hematomas were observed. In 35 sub-acute hematomas, peripheral hyperintensity could be observed on T1- and T2-weighted pulse sequences. This hyperintensity eventually fills in the hematoma in the chronic stage. In 17 chronic hematomas, a peripheral hypointense ring due to hemosiderin deposits was seen on T1- and T2-weighted scans. The authors conclude that high-field MR imaging is a very sensible diagnostic method in the evaluation of sub-acute and chronic hematomas.
