[The first 25 years of digestive radiology].

The first medical radiological attempts used the natural contrasts of the human body: bones of the limbs, intra-alveolar air of the lung; but as regards the abdomen, one could only observe gases or eventually calcified calculi. Whence the idea of a product opaque to the X-rays, not toxic, in order to obtain an internal cast of the various segments of the digestive tractus, making them thus visible by radiology. After little demonstrative trials of opaque sounds and capsules containing opacifying substances, there was an orientation towards the bismuth salts: sub-nitrate and carbonate generally used as therapeutical agents. In all the countries, engineers and physicians thrived to fit the equipment and experiment techniques of serial radiographies. Rieder, a radiologist from Munich perfected in 1905 the "meal" wearing his name (gruel of food and bismuth salts) adapted nearly everywhere. The radiological technology developed itself accordingly, creating progressively performant material. Finally, Paul Krause from Bonn and his team preconized in 1910 the use of insoluble baryum sulfate in watery suspension of which the purification was from now on assured. This product will be universaly used as a "gruel" or a "baryted milk" for the aesophago-gastro-duodenal transit and as a baryted enema for the examination of the colon.

[Unilateral isthmic lysis in x-ray computed tomography].

Condensing pediculolaminar hypertrophy of mechanical origin is known as "Dahu's sign". Dahu's sign corresponds to hypertrophy of the vertebral hemi-arch found by CT scan and leads to suspicion of controlateral lysis of the isthmus. It is the CT scan equivalent of vertebral "anisocorism" by conventional radiology.

[Lumboradiculalgia and calcified disk hernia].

In the context of a particular case report, the authors recall that calcified discs may be responsible for root pain, hyperalgic sciatica or lumbago. In the present case, the pain responded to intra-discal injection of long-acting corticosteroids. The authors compare this case to 10 other personal cases and 16 cases reported in the literature.

[The labrum acetabular. Apropos of 121 arthrographies of the hip in adults].

The authors report a retrospective study of 121 arthrographies of the hip in adults, excluding prostheses. The study was based on normal pathological values for angular measurement of the labrum acetabular: ECB angle (mean value: 15 degrees) enlarging the lateral cover of the head of the femur, VCE angle (mean value: 30 degrees) and a mean global VCB angle of 45 degrees. A certain equilibrium was observed between the covering capacity of the acetabulum and the covering capacity of the labrum acetabular. Numerous anomalies of the labrum were observed, including fissures in about 30% of cases. A large number of fissures were associated with other degenerative anomalies of the hip joint. A few fissures resulting in detachment of a strip of labrum were isolated and the possibility of their traumatic etiology and their pathogenic nature in clinical symptoms are discussed.

[Desmoid fibroma of the abdominal wall. Apropos of a case].

A case of desmoid fibroma of anterior abdominal wall, an exceptional benign tumor, is reported. Based on results of CT scan imaging of this lesion, differential diagnosis of other expansive processes of abdominal wall are discussed. This benign tumor is a potentially serious lesion due to its infiltrating character and the high incidence of recurrence. The need for total surgical excision is emphasized.

[Sciatica caused by synovial cysts and lumbar articular diverticula with intraspinal development. Saccoradiculographic, computed tomographic and arthrographic study].

The authors report 8 cases of patients with synovial cysts (3 cases) or diverticuli (5 cases) of the lumbar joints, compressing the sciatic roots. They describe the radiological aspects of the two sides of the degenerative pathology of the posterior articular processes, which are relatively unrecognized (14 cases in the literature). They insist on the advantage of saccoradiculography which is the only test to be able to demonstrate dynamic alterations in relation with diverticuli, if performed in a standing position. The authors show the advantage of tomodensitometry which supports the diagnosis of cyst in the presence of a fibrous wall image. They emphasize the value of the arthrography of the posterior joint; it presents a diagnostic role by visualizing the cavities, and a therapeutic role by permitting the injection in situ of steroids and/or local anesthetics.

[Spontaneous fracture of the sternum].

Spontaneous fractures of the sternum are unusual. They can simulate cardio-thoracic emergencies. A case of stress fracture of the sternum and of the femoral neck in a patient with corticosteroid induced osteoporosis is reported and the peculiar value of CT assessing the absence of tumoral mass is emphasized.
