    Notes: Abstract Infectious sacroiliitis is an uncommon septic arthritis, the diagnosis of which is difficult to establish. We retrospectively examined 14 cases of septic sacroiliitis, by CT (two of whom also had an MRI examination). The patient population consisted of eight men and six women; 9 were African, 8 had tuberculous sacroiliitis and 6 pyogenic sacroiliitis. All the cases showed a pre-sacroiliac soft tissue swellilng with ring-like enhancement following intravenous contrast in eight cases. A gas image was observed at the centre of the abcess in two cases. Joint narrowing was found in four patients and widening in eight, associated with an image of bone sequestration in seven, CT gave an etiologic orientation in 8 cases, and facilitated the guidance of bone biopsy. MRI showed low signal T1-weighted images and high signal T2 of the subchondral bone, joint space and soft tissue abcess. We conclude that CT is helpful in the evaluation of infectious sacroiliitis, and that further studies are necessary to evaluate the role of MRI in such pathologic processes.

    Notes: Summary  Neurenteric cysts are cystic lesions lined by a columnar epithelium of endodermal derivation. They are rarely located in the central nervous system. We describe the case history of two recurrent neurenteric cysts located within the posterior fossa: one in the 4th ventricle and the second in the cerebellopontine angle. The literature is reviewed and the follow-up and recurrence of such cysts are discussed.

    Notes: Summary The authors treated 38 cases with cervical disc prolapse and discoradicular pain by percutaneous Chemonucleolysis. Material and procedure are described and the results of 31 cases with a follow-up between 3 and 52 months analysed. The global results were excellent. In detail the results are analysed according to symptomatology, aetiology, findings of discography and the dose of enzyme used.

    Notes: Abstract A suprasellar location of a benign choroid plexus papilloma is reported. Local recurrence within the fourth ventricle was also present, 8 years after apparently complete removal. Imaging and histological findings were similar to those of the initial lesion. At surgery, the suprasellar lesion had no connection with the ventricular system. Seeding of choroid plexus papillomas is discussed, and the pertinent literature reviewed.

    Notes: Abstract A new method of posterior C1-2 arthrodesis, derived from the W. V. Cone and G. Bertrand, technique (Montreal, 1970) is described with two modifications: (1) the exact measurements of the ideal graft are determined preoperatively, using CT and a sterilized pasteboard horseshoe-shaped model; (2) in the sitting postion, single occipital block graft was cut out microsurgically, using the preoperative model. After decortication of the graft, posterior arches of C1 and 2, and microsurgical excision of the cartilage of the C1-2 lateral joints, the graft was imbedded into the entire C1-2 space, fixed, and tightened using a braid of “nylacap” yarn. A case report of rotatory luxation and associated atlantoaxial instability in a 10-year-old girl illustrates the excellent functional results of this technique.
