Magnetic resonance imaging assessment of sacroiliac joint involvement in Gaucher's disease.

A young woman with Gaucher's disease experienced acute pain in her right sacroiliac (SI) joint. Although pelvic radiographs and computed tomographic scan showed no significant change in the right SI joint, magnetic resonance imaging demonstrated an area of high signal intensity in the iliac part of the right SI joint, and a periosseous collection of blood. This skeletal location is rarely reported in Gaucher's disease; the mechanism of bone crisis is still controversial and our case suggests the occurrence of a bone infarct.

[Radiologic anatomy of the wrist].

Wrist imaging still relies first on plain X-Ray films, MRI allows excellent appreciation of the sculture of bones, ligaments, tendons and even nerves. C.T. is essentially useful in traumatology, while Wrist arthrography can be useful for detection of small ligament lesions.

[Anulography].

Despite new imaging modalities such as MRI, the discography remains useful, particularly as the first step of chemonucleolysis. The anulography corresponds to a technical error due to the wrong position of the needle during the procedure. We have noticed 32 anulographies on 1226 discographies done in our department, between 1985 and 1989. The anulography exhibits a typical pattern that must be diagnosed; if not, that can lead to a diagnosis mistake or a wrong therapeutic attitude. The needle of discography must then be repositioned.

[The dural sheath in the sitting and standing position during saccoradiculography. Apropos of 150 cases].

Lateral images were studied in the sitting and standing positions during a continuous series of 150 radiculographies, in patients presenting with a symptomatology suggestive of herniated disk or lumbar stenosis. In 67% of cases the dural sac was abnormally reduced at the level of the inter-somatic spaces, due to disk protrusion or intracanalar protrusion of posterior soft tissues. In 23% of cases, an absolute canalar stenosis with anterior-posterior decrease to less than 10 mn in the standing position existed. This was due in 65% of cases to an isolated or predominant posterior impression, the latter appearing in the standing position in only 55% of cases. Saccoradiculography is the only procedure allowing study of the dural cul-de-sac in the standing position. It should be carried out if a narrow lumbar canal is suspected clinically, even if investigations in the lying position, such as CT scan or MR imaging show normal canalar dimensions.
