[Headache of cervical origin].

The authors recall cervical etiologies of headache. They distinguish on the one hand the cervico-occipital region with minor and major malformations and acquired lesions, and on the other hand the middle and inferior cervical segment. They also recall the original structuralist analysis of the cervical spine and give the example of the "cervical triplet".

[Polarity of the radiological image. Practical applications].

The author considers the polarity "above-below" of a radiological image and makes three remarks: The image perception is better memorized when the axis of "gravity" and of "flow" and identical. When both axis, of gravity and flow, are opposite, it is very difficult to find the best didactic method of teaching the image. Experienced radiologists use since a long time a method of "depolarisation of the image". To improve the elementary perception of ribs, they turn (90 degrees, 180 degrees, 270 degrees) the image of a costal grid.

[Structuralist reading of radiologic images].

The author suggests analysing the radiological image according to classical principles of structuralism, gestaltism, semiology, semantics. He describes applications in routine radiology: perception of complete theoretical displacement of parts of the image, phenomenology of three images (A-B-C) in theory and exams, mistake in perception by analogy.

Spinal subdural metastasis. A case report.

A case of metastasis to the thoracic spinal subdural space is reported. Metrizamide myelography showed narrowing of the upper thoracic subarachnoid space. A tumor in the spinal subdural space is unusual; only a few cases have been reported. The myelographic appearance is not specific; an epidural metastasis can produce the same myelographic picture.

CT findings in malignant meningiomas.

Recurrent meningiomas are due usually to incomplete removal as in the case of basal meningiomas where the tumour surrounding vessels and nervous structures cannot be completely excised. Recurrent meningiomas of the convexity are rare after resection. In most recurrent cases histological changes are noted which may explain the rapid growth, the aggressive nature and also the malignancy of the tumour. These changes include increased mitotic activity, necrosis and invasion of the adjacent brain parenchyma. CT findings in malignant meningiomas are related to the microscopic appearance of these tumours: tumoral necrosis determines heterogeneous enhancement; brain invasion explains the irregular outline of the tumour and sometimes the absence of surrounding low attenuation area. The authors report 5 malignant meningiomas in which the CT findings are correlated with the microscopic findings.

Percutaneous puncture of spinal cysts in the diagnosis and therapy of syringomyelia and cystic tumors.

The experience with percutaneous puncture of intraspinal cystic lesions is reported in four cases: an extradural cyst demonstrated with air, a spinal cord tumor with lipiodol and two cases of syringomyelia with metrizamide. Percutaneous puncture of cystic lesions makes possible an accurate delineation of the lesion and a histological approach through biochemical and cytological analysis of the aspirated cystic fluid, while aspiration of the fluid of cystic tumors decompresses the spinal cord and thus plays a therapeutic role.

Constitutional narrowness of the lumbar spinal canal and cheiro-lumbar dysostosis.

The author reports a further case of cheirolumbar dysostosis (associated of Verbiest's constitutional narrowness of the lumbar canal and short and broad phalanges and metacarpals) and a case with multiple malformations including both the narrow lumbar canal and brachycheiry and also several other malformations of the bones. The author discusses the nosography of Verbiest's syndrome with regard to cheirolumbar dysostosis and to more complex and diffuse malformations.

[Spondylocostal dysostosis and polydactylia].

The authors report the case of a 22-month-old boy who presented a spondylocostal dysostosis associated with preaxial polydactylia. This peculiar malformation syndrome seems to be the first reported in the literature till today.
