Anterior clinoid mucocele: a trans-nasal endoscopic approach.

The goals of the treatment of paranasal sinuses mucocele are the relief of the symptoms due to compression and the prevention of recurrence. Because of the benignity of the pathology, it is mandatory to choose the approach that minimizes the surgical trauma. When an anterior clinoid mucocele is found, the conventional approaches are the trans-nasoethmoidal, the subtemporal or the pterional ones: we think that as a really mini-invasive approach, the transnasal endoscopy may be proposed. Anterior clinoid localization may be reached by a trans-sphenoidal way and treated by endoscopic microsurgery with a very low morbility. This paper deals with a case of anterior clinoid mucocele treated by this way with good anatomic and functional results and stresses the importance of the pre-operative imaging (CT/MR) allowing one to make a sure diagnosis and to choose the cases suitable for this surgical approach.

CT in low back and sciatic pain due to lumbar canal osseous changes.

In a consecutive series of 600 patients scanned by CT for various spinal diseases, those with low back and sciatic pain without disc herniation were selected for study. The causes proved to be joint facet degeneration (32 cases), stenosis of the neural foramina (13 cases), stenosis of the spinal canal (13 cases), lateral recess stenosis (6 cases) and spondylolisthesis (6 cases). The predominance of joint facet pathology as the underlying cause of low back and sciatic pain in the absence of disc herniation is confirmed. CT scanning of the soft tissues as well as of the skeletal structures is crucial to the aetiological diagnosis of the condition under study and hence to the proper planning of treatment.

Degenerative changes in hypophyseal adenomas: CT features.

16 patients with hypophyseal adenoma undergoing degenerative changes, namely necrotic-cystic changes, bleeding and calcification, were subjected to CT and the resulting density values studied. The cases were verified at operation and at histological examination. Evaluation of these features, despite the limitations of the method, proved to be very useful in differential diagnosis and in the planning of treatment.

Magnification angiography of the small vessels in cerebrovascular disease in advanced age.

Vascular changes in the cerebral arterioles (150 - 500 mu) were demonstrated by means of magnification serial cerebral angiography (focal spot 0.15 mm) in a consecutive series of 25 hypertensive patients of advanced age suffering from cerebrovascular disease. The changes identified were: (a) arteriosclerotic lesions, (b) arteriolar occlusion, and (c) miliary aneurysms. The enhancement of vascular details obtained is essential to arrive at exact diagnosis and accurate clinical management.
