    Notes: Abstract This study has been performed to define better the anatomical structure of the oculomotor nuclear complex and its neuronal components. The oculomotor nuclear complex was examined in fixed and serially sectioned midbrains from 12 adult subjects free from neurological diseases. The complex included the somatic portion, (formed by multipolar motor neurons), and the parasympathetic portion, (formed by oval or fusiform preganglionic cells), on each side of the median raphe. The somatic portion consisted of the lateral somatic cell column and the caudal central nucleus. The somatic column measured from 0.2 × 0.1 mm to 3.4 × 1.4 mm (X = 2.4 × 1.2 mm) in transverse section. It was divided into the principal, intrafascicular and extrafascicular parts. The principal part was subdivided into the dorsal, intermediate and ventral portions. Isolated multipolar neurons were also found in the periaqueductal gray matter, the interstitial nucleus of Cajal, the Edinger-Westphal nucleus and the fibre bundles of the oculomotor nerve. These cells most likely represent the displaced motor neurons of the oculomotor nerve. The caudal central nucleus was 0.8 × 0.6 mm in size. The Edinger-Westphal nucleus consisted of the rostral, ventral and dorsal parts; the longest rostrocaudal diameter of this nucleus measured 7.1 mm. The anatomical data of our study are relevant clinically and allow explanation of the neurologic signs following complete or partial lesions of the oculomotor nuclear complex.

    Description / Table of Contents: Résumé Cette étude a été entreprise pour mieux définir la structure anatomique du complexe nucléaire du n. oculomoteur et ses composants neuronaux. Le complexe nucléaire du n. oculomoteur a été examiné sur les troncs cérébraux fixés et coupés en série, provenant de 12 adultes exempts de maladie nerveuse. Le complexe comprenait la portion somatique (formée par des neurones moteurs multipolaires) et la partie parasympathique (formée par des cellules pré-ganglionnaires ovales ou fusiformes) de chaque côté du raphé médian. La portion somatique était formée par la colonne somatique latérale et le noyau caudal central. La colonne somatique mesurait entre 0,2 × 0,1 mm et 3,4 × 1,4 mm (moyenne = 2,4 × 1,2 mm) sur les coupes transversales. Elle était divisée en parties principale, intrafasciculaire et extrafasciculaire. La partie principale était subdivisée en portions dorsale, intermédiaire et ventrale. Des neurones multipolaires isolés ont également été trouvés dans la substance grise péri-aqueductale, le noyau interstitiel de Cajal, le noyau d'Edinger-Westphal, et les faisceaux des fibres du n. oculomoteur. Ces cellules représentent très vraisemblablement des neurones moteurs déplacés du n. oculomoteur. Le noyau caudal central mesurait 0,8 × 0,6 mm. Le noyau d'Edinger-Westphal comprenait les parties rostrale, ventrale et dorsale ; son plus long diamètre rostro-caudal mesurait 7,1 mm. Les documents anatomiques tirés de notre étude sont importants en clinique et permettent d'expliquer les signes neurologiques consécutifs à des lésions complètes ou partielles du complexe nucléaire du n. oculomoteur.

    Notes: Abstract Many anomalies may involve the ophthalmic and middle meningeal arteries, because of the close relationship of their development. The system of the ophthalmic artery may supply the dural convexity by the middle meningeal artery of ophthalmic origin, the anterior branch of the middle meningeal artery or an accessory meningeal artery. The development and the anatomic arrangement of these anomalous vessels are discussed. Three cases of meningiomas of the brain convexity supplied by anomalous meningeal arteries arising from the ophthalmic artery are described. In one case internal carotid angiography showed an anomalous anterior branch of the middle meningeal artery arising from the ophthalmic artery, whereas the maxillary artery provided only the posterior branch of the middle meningeal artery. In two cases the middle meningeal artery system was normal, but the ophthalmic artery provided an accessory meningeal artery supplying the meningioma. Whereas an ophthalmic origin of the middle meningeal artery is rather common, the angiographic finding of an accessory meningeal artery or an anterior branch of the middle meningeal artery arising from the ophthalmic arterial system is exceptional. The preoperative embolization of dural lesions supplied by anomalous meningeal vessels of ophthalmic origin is dangerous because of the risk of embolization into the ophthalmic circle.

    Description / Table of Contents: Résumé Un grand nombre d'anomalies touche les aa. ophtalmique et méningée moyenne en raison de leurs liens embryologiques. Le système de l'a. ophtalmique peut vasculariser la dure-mère de la convexité lorsqu'elle donne naissance à l'a. méningée moyenne ou à sa branche antérieure, ou à l'a. méningée accessoire. Le développement et la disposition anatomique de ces anomalies vasculaires sont discutés. Trois cas de méningiomes de la convexité, alimentés par des aa. méningées provenant de l'a. ophtalmique, sont décrits. Dans un cas, l'opacification de l'a. carotide interne montrait que la branche antérieure de l'a. méningée moyenne provenait de l'a. ophtalmique ; l'a. maxillaire ne donnait alors que sa branche postérieure et l'a. méningée moyenne. Dans deux cas, le système de l'a. méningée moyenne était normal, mais l'a. ophtalmique donnait une a. méningée accessoire vascularisant le méningiome. Alors que l'origine ophtalmique de l'a. méningée moyenne est relativement commune, la naissance à partir de l'a. ophtalmique de l'a. méningée accessoire ou de la branche antérieure de l'a. méningée moyenne est exceptionnellement décrite en angiographie. L'embolisation pré-opératoire des lésions durales alimentées par les vaisseaux méningés anormaux provenant de l'a. ophtalmique est dangereuse en raison des risques oculaires.

    Notes: Abstract The territories of the central branches of the middle cerebral artery (MCA) were examined in 21 injected human brains. It was noted that these central arteries supplied: the caudate nucleus (dorsolateral half of the rostral part of its head; the entire caudal part of the head; the body and rostral portion of the tail in some cases), the putamen (dorsolateral part of its rostral portion, the remainder of the putamen, except the most caudal part occasionally), the globus pallidus (the entire lateral segment, except the ventrorostral and, sometimes, the most caudal part), the basal forebrain (lateral parts of the basal nucleus of Meynert and the nucleus of the diagonal band, as well as fiber bundles in this region), the internal capsule (dorsal and ventrocaudal part of the anterior limb, dorsal part of the genu, dorsal and ventrorostral part of the posterior limb), the corona radiata (a narrow strip close to the internal capsule) and the cerebral cortex (the caudal orbitofrontal cortex occasionally). The presented data may have certain neuroradiologic, neurologic and neurosurgical significance.

    Description / Table of Contents: Résumé Le territoire des artères centrales nées de l'ACM a été étudié sur vingt et un cerveaux humains injectés. Les artères centrales vascularisent : le noyau caudé (la moitié dorso-latérale de la partie rostrale de sa tête ; la totalité de la partie caudale de sa tête ; dans certains cas son corps et la partie rostrale de sa queue), le putamen (la partie dorso-latérale de sa portion rostrale ; parfois le reste du putamen, à l'exception de sa portion la plus caudale), le globus pallidus (la totalité de son segment latéral sauf sa partie ventro-rostrale et parfois sa portion la plus caudale), le cerveau basal (parties latérales du noyau basal et noyau de la bandelette diagonale, de même que les faisceaux des fibres de cette région), la capsule interne (partie dorsale et ventro-caudale du bras antérieur ; partie dorsale du genou; partie dorsale et ventrorostrale du bras postérieur), la couronne rayonnante (étroite bande bordant la capsule interne) et le cortex cérébral (parfois la partie caudale du cortex orbito-frontal). Ces données peuvent avoir une certaine importance en neuro-radiologie, neurologie et neuro-chirurgie.

    Notes: Abstract Diaphragma sellae meningiomas are unusual tumours often not distinguished from pituitary macroadenomas. Preoperative differentiation is essential, because the trans-sphenoidal approach is used for surgical removal of adenomas, while meningiomas are approached via a craniotomy. We reviewed five patients in whom a diaphragma sellae meningioma was initially diagnosed as a nonsecreting pituitary macroadenoma. MRI criteria for differential diagnosis are discussed. The main findings considered are visibility of the pituitary gland, contrast enhancement, the centre of the lesion and sellar enlargement. These criteria, applied to a blind review, allow correct identification of the tumours.

    Notes: Abstract Ossification of the yellow ligament (OYL) is not infrequent in the cervical and lumbar regions but is very rare in the thoracic spine, with no more than 40 cases reported in the literature. We describe a 50-year-old male with progressive paraparesis and sensory dysfunction, secondary to OYL at T10–T11, studied by computed tomography (CT) and magnetic resonance imaging (MRI). Decompressive laminectomy and removal of the ligament resulted in marked clinical improvement. Patients with OYL may initially develop sensory dysfunction associated with leg weakness. This pathological entity can be well defined by CT and MRI, and surgery by decompressive laminectomy is advised for all cases. The OYL should be removed both posteriorly and laterally to the dural sac to obtain sufficient decompression of the spinal canal.

    Notes: Abstract Ossification of the posterior longitudinal ligament (OPLL) of the cervical spine is a frequent pathological entity in people of Japanese and Asian extraction and is reported with increasing frequency also in the USA; on the contrary, reports in the European and particularly in the Italian literature remain rare. This paper describes 8 Italian patients with cervical spine stenosis due to OPLL extending three to five vertebral segments (and above C3 in four cases). Magnetic resonance imaging shows the extent of the ossification well in terms of height and cord compression, while computed tomography is useful to measure the thickness of the bone mass and the residual spinal canal. Anterior cervical decompression by discectomy, corpectomy, and removal of the ossified ligament is the treatment of choice and results in clinical improvement in most cases. Decompressive laminectomy may be reserved for patients with ossification extending to four or five levels and above C3. The surgical technique and intraoperative findings are discussed.
