    Notes: Abstract. The purpose of this study was to evaluate and compare the radiographic efficacy and safety of iodixanol (Visipaque; 270 and 320 mg I/ml) and iohexol (Omnipaque; 300 mg I/ml) in myelography. The study was randomized, double-blind and comparative including 398 patients from five European university clinics. The radiographic visualisation was evaluated as poor, good or excellent. Adverse events were recorded by interviewing the patients after the myelography, and each patient was given a questionnaire to be returned after 1 week. In cervical myelography with cervical puncture more films with excellent quality was obtained after iodixanol 320 mgI/ml compared with iohexol 300 mgI/ml (p = 0.009). Also in lumbar myelography iodixanol 320 mgI/ml compared favourably with iohexol 300 mgI/ml (p = 0.006). The most frequent adverse event was headache, which occurred in 5–35 % of patients during the first 24 h and in 19–61 % within the first 7 days, depending on the centre. There was no difference in frequency and severity of the adverse effects between the contrast media.

    Description / Table of Contents: Summary The authors present a case of epidermoid cyst in an unusual (intrasellar) situation and with untypical symptomatology (endocrine disorder without ophthalmological manifestations). The treatment was essentially surgical, and the patient's progress has been satisfactory.
    Notes: Résumé Les auteurs présentent un cas de kyste épidermoïde, de situation inhabituelle (intra-sellaire) et de symptomatologie peu courante (troubles endocriniens sans manifestation ophtalmologique). Le traitement fut essentiellement chirurgical et l'évolution de la patiente est satisfaisante.

    Description / Table of Contents: Résumé Les appareils tomoéchographiques à déplacement automatique de la sonde ultrasonore sont habituellement considérés comme peu adaptés à l'exploration encéphalique. Pourtant ils permettent chez l'enfant une excellente mise en évidence des limites ventriculaires. En fait, ainsi pratiquée, la tomoéchographie représente une méthode simple, fiable, non agressive, parfaitement adaptée à l'exploration de l'hydrocéphalie, notamment dans la période de surveillance post-opératoire après dérivation. Elle parait plus sûre et mieux intégrée à la radiologie que la simple échographie A.
    Abstract: Zusammenfassung Dit Tomo-Echographie ermöglicht besonders bei Kindern eine ausgezeichnete Darstellung der Ventrikelgröße. Die Untersuchung bereitet dem Patienten keine Beschwerden, sie ist besonders für postoperative Verlaufskontrollen angezeigt. Die Ergebnisse der Tomo-Echographie sind besser als die Ergebnisse der A-Echographie.
    Notes: Summary Tomoechographic examination with automatic displacement of the ultrasonic probe is usually looked upon as an inadequate technique for cranial exploration. However, in children it allows excellent examination of ventricular walls. In fact, such devices make echotomography a simple, reliable, non-painful diagnostic method in hydrocephaly, especially for post-operative monitoring of ventricular size. It seems a more reliablemethod and more in line with radiology than plain Aechography.

    Notes: Summary The supra sellar extension of even small sized pituitary adenomas can be delineated with accuracy by angiotomography. This technique avoids the discomfort of pneumoencephalography in many patients. Angiotomography is also useful for the differential diagnosis of empty sellae.

    Notes: Summary Five anatomical and radiological observations of a spine protruding into the pituitary fossa are reported. This osseous spine, about 4 mm long, arises in the midline from the inferior part of the anterior aspect of the dorsum sellae and extends upward and forward. The possible origins of this malformation are discussed.

    Notes: Summary The experience with percutaneous puncture of intraspinal cystic lesions is reported in four cases: an extradural cyst demonstrated with air, a spinal cord tumor with lipiodol and two cases of syringomyelia with metrizamide. Percutaneous puncture of cystic lesions makes possible an accurate delineation of the lesion and a histological approach through biochemical and cytological analysis of the aspirated cystic fluid, while aspiration of the fluid of cystic tumors decompresses the spinal cord and thus plays a therapeutic role.

    Notes: Summary A case of ossfication of the posterior longitudinal ligament (PLL) at the cervical level one year after cervical irradiation is reported. This condition is rare in Caucasian people. The cause is unknown. The particular circumstances of ossification occurence in the case reported allow us to propose a new etiological hypothesis.

    Notes: Summary The authors report the CT scan findings in a case of sellar spine. This osseous spine which arises in the midline of the anterior aspect of the dorsum sellae and is directed toward the center of the sella turcica has already been described on specimens and on plain films but never on CT scans. The CT scan findings confirm the normal appearance of the surrounding structures.

    Notes: Summary Symptomatic intrasellar Rathke's cleft cysts are rather rare: only a few cases with CT findings have been reported. The authors describe the CT appearance of 3. Histological aspects and embryology are discussed. Rathke's cleft cysts have to be differentiated from other intrasellar tumours: cystic craniopharyngiomas, cystic or necrotic pituitary adenomas, cysticercosis.

    Notes: Summary In the last few years complete or partial regression of prolactinomas has been demonstrated in nonpregnant women treated by bromocriptine. Thus bromocriptine therapy appears as an attractive alternative to surgery for management of infertility related to hyperprolactinemia. However, numerous reports emphasized the possibility of an excessive growth of the pituitary adenoma with visual field defects during the last 3 months of pregnancy. To avoid these complications, the authors followed with serial CT scans the growth of microprolactinoma at the 5th or 6th month of pregnancy. Among six pregnant women, one patient presented a marked upward extension of the adenoma. Bromocriptine was then reintroduced and the effectiveness in reducing tumor growth was proved by CT scan at the 7th month. Regarding low risk of using intravenous iodinated contrast medium in pregnant women and of fetal radiation damage, the authors emphasize the value of CT in the follow-up of bromocriptine-induced pregnancies.
