Case Reports
[Dissection of the vertebral arteries after manipulation of the cervical spine. Apropos of a case].
Dissecting aneurysm of the vertebral arteries following chiropractic manipulation of the spine. A thirty-five years old man had a Wallenberg Syndrome following chiropractic manipulation of the spine. ⋯ Arteriography lead to the diagnosis of dissecting aneurysm of the vertebral arteries. The favourable course point to the value of the posterior communicating arteries and the spinal artery as collateral pathways of the vertebro-basilar circulation.

Case Reports
[Tomodensitometric aspects of a case of intracranial toxoplasmosis in an immunosuppressed patient].
The case of a 42 years old man who had a monoblastic acute leukemia treated by a bone-marrow graft is described. The patient died of a cerebral toxoplasmosis and a cerebral computed tomography done two days before is correlated with anatomopathologic slices done in the same planes than the computed tomagraphy examination. ⋯ The immunocompromised patient is very favorable for the development of a cerebral toxoplasmosis. CT, while not specific, has the advantage to suspect the diagnosis which must be discussed with other oportunistic infections, leukemic infiltrates, methotrexate encephalopathy, progressive multifocal encephalopathy, and small infarcts.

A patient with Paget's disease developed an osteogenic sarcoma of the cranium. This emphasizes the need to conduct full neuroradiological investigations, including a CT scan and even selective arteriography as well as standard radiographs, whenever the possible existence of such a lesion is suspected, to determine therapeutic strategy.

3 cases of abnormalities of the inferior vena cava are reported: one isolated left inferior vena cava, one duplication of the inferior vena cava with continuation by a left inferior hemi-azygos vein and a simple duplication of the post-renal inferior vena cava. Finally, 2 cases of retro-aortic left renal vein are described. These abnormalities may be fully studied by computed tomography which in certain cases makes it possible to avoid inferior cavography. The authors emphasize potential sources of error in interpretation and the value of being aware of the congenital malformation of the inferior vena cava.

Case Reports
[Ultrasonographic diagnosis of a left inferior vena cava with hemiazygos prolongation (author's transl)].
A case of a left inferior vena cava with prolongation into a hemiazygos vein is reported, in which the diagnosis was suspected after ultrasonography and confirmed by inferior cavography. Ultrasonographic signs were absence of a retrohepatic inferior vena cava, direct opening of the inferior hepatic veins into the right atrium, and the presence of a longitudinal vascular structure behind and on the left of the aorta, corresponding to the left inferior vena cava.
