    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 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 The authors report radiological findings in 13 cases of avulsion of the posterior lumbar apophyseal ring. The lesion affected young adults in 10 cases and adolescents in 3 cases. The lesion involved the inferior endplate of L4 in 11, and of L5 in 1 patient, and of L3 in 1 patient. 6 patients presented with unilateral sciatica, 3 with bilateral sciatica, and 4 with low back pain. Acute spinal trauma was evident only in 2 adolescents. Radiological recognition of the lesion was possible on plain films in 9 cases. CT demonstrates association of avulsion of the posterior vertebral apophyseal ring and herniated disc in all cases. Avulsion of the posterior apophyseal ring has to be differentiated from posterior longitudinal ligament, annulus, or herniated disc calcifications, as well as from posterior degenerative ridge osteophytes. Controversy about physiopathology of the lesion remains: weakness of the apophyseal ring during childhood and in patients with Scheuermann's disease may explain avulsion of the apophyseal ring in association with median disc herniation.

    Notes: Summary We report a case of non-Hodgkin's lymphoma with CNS involvement confined to the epidural space causing cranial suture diastasis. Cerebrospinal fluid and bone marrow were normal. Two cases only of cranial epidural lymphoma have been reported in the literature; in both cases, the leptomeninges were also involved but without suture diastasis.

    Notes: Summary Forty-seven extraforaminal lumbar disc herniations (EFLDH) accounting for 7% of all lumbar disc herniations encountered during the same period of time were reviewed. L3–L4 or L4–L5 disc was involved in 89% of the cases giving rise to a L3 or L4 nerve root compression. An abnormal motion of lateral bending with rotation of the trunk was found retrospectively in 60% of the patients. In 53% of all EFLDH a bony avulsion of the vertebral endplante facing the herniation was demonstrated at the site of attachment of Sharpey's fibers. This study suggests that this previously undescribed bony change witnesses a special injury of the spine responsible for most EFLDH.

    Description / Table of Contents: Résumé II peut être important, pour le neuro-chirurgien, de savoir, avant d'opére, si une lésion expansive intra-cérébrale est ou non kystique; l'angiographie cérébrale conventionnelle répond mal à cette question; par contre, l'angiotomographie peut apporter la preuve de la nature kystique d'une tumeur cérébrale et en préciser le volume et la topographie.
    Abstract: Zusammenfassung Für den Neurochirurgen ist es oft wichtig zu wissen, ob ein Gehirntumor ein zystische Komponente hat oder nicht; die koventionelle zerebrale Angiographie beantwortet diese Frage nicht ausreichend; die Angiotomographie dagegen, kann den Beweis der zystischen Natur eines Gehirntumores bringen, sein Volumen und seine Topographie bestimmen.
    Notes: Summary Cysts in cerebral tumours, as small as 1 cm in diameter, have been demonstrated by angiotomography with the sections made in the frontal plane. Two signs suggest a cystic lesion; a geometrically round, vessel-like outline in either the arterial or venous phase, resulting from a cystic cavity under pressure, and, during the parenchymatous phase, a radiolucent area having a radiological contrast identical to the non-injected hemisphere.

    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 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 The authors report three cases of lumbar apophyseal joint lipoma located at the L4/L5 or L5/S1 level. CT scan makes the diagnosis easily possible; indeed erosive changes with enlargement of the upper portion of the lumbar articular joint and anterior displacement of the top of the superior facet are associated with intra-articular fatty densities. Clinical symptoms are rarely encountered and may be related to narrowing of the upper portion of the intervertebral foramen.
