The commissuro-mamillary plane in MRI of the brain (preliminary communication).

MRI sections of the brain in the coronal plane through the line joining the anterior commissure and the mamillary bodies display the constituent parts of the basal forebrain. The visualisation of the septal nuclei and the anterior columns of the fornix show the importance of this plane in the study of behaviour disorders and amnesic syndromes.

[Scanner-guided puncture biopsy of a lesion occupying the pterygo-maxillary fossa].

A 26-year old male patient was referred to us for impaired mouth opening. Actually, Mr. B. has been followed up for SADAM for 2 years at different hospital services. In view of the ineffectiveness of the treatments administered (occlusal releasing gutter, antiinflammatory agents) and due to occurrence of severe episodes of earache refractory to conventional analgesics, we request that a CT-scan be obtained to evidence the process invading the pterygopalatine fossa. ENT examination and scanner-guided needle biopsy are performed to enable anatomopathological analysis and diagnosis.

[The diagnostic importance of different imaging technics in temporomandibular joint dysfunction].

Various imaging techniques enable to explore the Temporo-mandibular joints (T.M.J.). The physicians prescribing them, must be perfectly aware of the informations they provide as well as their costs, for a judicious formulation of their indications. Conventional radiography is absolutely necessary and, most of the time, sufficient, since it simply permits to evaluate the bony structures. An orthopantomogram and modified Schüller views of each T.M.J., "open mouth" and "closed mouth" will be performed. Conventional tomograms are no longer indicated. They will be abandoned for Computed Tomograms. This examination permits, at a relatively low cost, to analyse a bony abnormality and explore the muscular soft tissues. It may also be possible to assess the meniscus, its position and displacement when the mouth is opened. In fact, if a meniscal or articular pathology is considered, which could result in surgical or endoscopic procedure, it is absolutely necessary to perform: -either an arthro-tomography, with contrast material, -or a magnetic resonance examination. The latter provides perfect anatomical and pathological informations of the joint and meniscus, in an atraumatic fashion for the patient. Its only contraindication is in the cost of the examination. It will be possible to look for a dislocation, a malformation or a structural alteration of the meniscus which could result in a perforation, a rupture of the posterior frenulum, adhesions or joint extravasation. A necrosis or early osteochondritis of the condyle will be ruled out.

[Inter-apophyseal articular synovial cyst of the lumbar spine. X-ray computed tomographic and magnetic resonance imaging correlation. Apropos of 2 cases].

Two patients presenting with L5 radiculagia were investigated by CT scan imaging. The origin of the pain was determined with certitude as arising from intraspinal development of an interapophyseal synovial cyst. Examination of the two cases by MR imaging provided conflicting results: in one patient images obtained by MR were not contributive and the synovial cyst would probably have been missed while in the other patient images were specific and very sensitive for diagnosis of interapophyseal synovial lesions. Treatment was surgical in both cases.
