    Notes: Abstract  Chondromyxoid fibroma is a rare benign cartilaginous tumour seen most frequently around the knee in children and young adults. Up to 17% occur in the foot, where more aggressive appearances have been reported. Four cases of chondromyxoid fibroma in the forefoot are presented, demonstrating the wide range of radiological appearances of this primary tumour. Three of the four tumours recurred, one at 19 years after surgery. These cases illustrate the need for thorough preoperative assessment to ensure complete surgical resection in an attempt to reduce the incidence of local recurrence.

    Notes: Abstract A retrospective study was performed to determine whether bone blood supply can be assessed on gadolinium-enhanced magnetic resonance imaging. Lumbar spine magnetic resonance imaging (MRI) examinations of 49 patients attending for post-laminectomy examination were reviewed (30 male, 19 female, mean age 46.4 years, age range 23–84 years). Each study included sagittal T1-weighted spin echo sequences before and after gadolinium administration. Regions of interest were drawn within the L3 vertebral body from a parasagittal slice from each sequence. Signal intensity (SI) values were ascertained and the percentage increase in SI was calculated. For each patient, changes in receiver gain for pre and post-gadolinium images were corrected by an image scaling factor. In all cases, a measurable increase in SI was found (mean 15.3%, range 4.4–55.7) due to bone vascularity. The results give no indication of the quantity or timing of blood supply but provide a basis for further work.

    Notes: Abstract Five patients with pigmented villonodular synovitis (PVNS) of the knee demonstrate the value of preoperative, contrast medium-enhanced CT scanning. The technique is shown to be particularly useful in locating recurrent lesions and in demonstrating that popliteal and posterior calf masses are due to PVNS affecting the knee joint itself. In two of the five patients PVNS was not considered a possibility before the CT scan, and none had evidence of bone erosion on plain radiographs. In none of the patients was the unenhanced CT scan able to demonstrate evidence of decreased radiolucency due to fat within the tumour or density greater than the adjacent skeletal muscle, indicating haemosiderin deposits.

    Notes: Abstract Five cases of septic sacroiliitis diagnosed by magnetic resonance imaging (MRI) are presented. Imaging was performed between 2 and 14 days after onset of symptoms and consisted of varying combinations of coronal short tau inversion recovery (STIR), axial T2-weighted spin echo (SE), and coronal and axial pre- and postcontrast T1-weighted SE scans. Abnormalities included demonstration of sacroiliac joint effusions, bone oedema and adjacent inflammation as high signal on STIR and T2-weighted SE scans, and identification of abscesses in two cases as rim-enhancing lesions anterior to the joint on gadolinium-enhanced T1-weighted SE scans. The role of MRI and other forms of imaging in septic sacroiliitis is discussed.

    Notes: Abstract Bilateral three-compartment wrist arthrography was performed in 30 patients with unilateral posttraumatic wrist pain to assess the incidence of bilateral findings. The mean age of patients was 30 (range 18–55) years. Thirty-three percent of patients were normal bilaterally, 30% had unilateral communication in the symptomatic wrist, 30% had communications in both the symptomatic and asymptomatic wrists and 7% had communication in the asymptomatic wrist only. Unilateral three-compartment wrist arthrography is not recommended in the assessment of unilateral post-traumatic wrist pain; no advantage of three-compartment injection over radiocarpal injection alone was shown.
