    Notes: Abstract. Intra-articular ganglion cysts of the cruciate ligaments are associated with non-specific clinical signs and symptoms. Familiarity with the MR appearances in particular is important to make an accurate diagnosis, exclude associated abnormalities, and avoid misdiagnosis.

    Notes: Abstract. Spinal infection is a significant cause of morbidity. Despite advances in antibiotic treatment regimens, the incidence is not decreasing due at least in part to an increase in 'at-risk' populations, namely the elderly and the immunocompromised. Prompt diagnosis is greatly facilitated by early and appropriate imaging techniques together with microbiological assessment following culture from blood, needle aspirate and biopsy material. This article gives an overview of imaging of spinal infection with an emphasis on MR imaging, which has greatly contributed to early diagnosis, thus allowing implementation of timely appropriate treatment.

    Notes: Abstract. The increasing application of magnetic resonance (MR) imaging of the spine has raised the awareness of lumbar facet synovial cysts (LFSC). This well recognised, yet uncommon condition, presents with low back pain and radiculopathy due to the presence of an extradural mass. The commonest affected level is L4/5 with a mild degenerative spondylolisthesis a frequent associated finding. MR imaging is the technique of choice to detect and diagnose a LFSC. This pictorial essay, drawing on experience of 43 cases seen in 40 patients, illustrates the spectrum of appearances that can be encountered and suggest differing causes for the variable signal characteristics exhibited. Computed tomography (CT) can be of value in some cases to aid interpretation of the MR images. In addition, CT facet arthrography by injection of air or iodinated non-ionic contrast medium may be used to confirm the diagnosis in doubtful cases as well as noting whether the patients presenting symptoms can be provoked. A comprehensive review of the existing literature is presented.

    Notes: Abstract. Disc prolapse presenting with sciatica may be associated with enhancement of the symptomatic nerve root following magnetic resonance imaging (MRI) with intravenous gadolinium (Gd)-DTPA. Previous studies have shown, however, that this does not occur in all cases. The aim of this study was to assess the incidence of nerve root enhancement in patients with sciatica and disc prolapse and to try to identify any specific features that might be associated with the phenomenon. A total of 227 patients presenting with low back pain and/or sciatica underwent a MRI study of the lumbar spine with intravenous contrast enhancement. Nineteen of 81 (23.5 %) patients with disc prolapse demonstrated nerve root enhancement. Nerve root enhancement had a highly significant association with sequestrated disc lesions (13/19, 68 %; P 〈 0.0005), and was primarily seen in the symptomatic ipsilateral nerve root (16/19, 84 %). The sensitivity of nerve root enhancement associated with disc prolapse was 23.5 % with a specificity of 95.9 %, a positive predictive value of 76 % and a negative predictive value of 69.3 %. Nerve root enhancement may be indicative of the symptomatic level but its poor sensitivity negates the routine use of Gd-DTPA in MRI for sciatica.

    Notes: Abstract Cervical myelopathy in patients with Down’s syndrome is not uncommonly the result of atlanto-axial instability, a condition that is caused by ligamentous laxity and which may be associated with congenital osseous anomalies at the occipito-atlanto-axial axis. Ossification of the posterior longitudinal ligament (OPLL) is well described, particularly in the Japanese population, and may be associated with diffuse idiopathic skeletal hyperostosis. This is the first case, to our knowledge, of OPLL occurring in a person with Down’s syndrome presenting with myelopathy.

    Notes: Abstract  Chordomas of the lumbar vertebral bodies are rare. We report an unusual case of an entirely intra-osseous chordoma of the fifth lumbar vertebra treated by vertebrectomy. Conventional radiographs and scintigraphy were normal. The lesion was well visualised by MR imaging, but showed only slight sclerosis on CT. We give our reasons for making a diagnosis of chordoma rather than giant notochordal rest and discuss the problems of management resulting from this diagnostic dilemma.
