[Painful sequelae of Wallenberg's syndrome].

Twenty-seven out of 45 patients who had Wallenberg's syndrome were re-examined as out-patients. Nineteen were complaining of pain on the side opposite to that with loss or temperature and pain sensations or trigeminal deficit. The follow-up showed that pain was both intense and disabling and its treatment was disappointing. The most striking finding was the high frequency of painful sequelae to Wallenberg's syndrome, since they affected almost one out of two patients. The occurrence of these painful symptoms, usually after lesion of the spinothalamic tract, is difficult to explain.

[Meningioma with pseudo-vascular disclosure].

In a retrospective study of 125 case reports of intracranial supratentorial meningiomas, the authors have isolated 10 patients whose meningioma had been revealed by pseudo-vascular syndromes. Mean age and sex ratio were the same in this group of patients as in those patients whose meningioma had been more classically disclosed by an epileptic seizure, a motor or a progressive sensorimotor deficit. The site of the tumour exerted an influence on the nature of clinical manifestations. There was no correlation between the size of the tumour and the transient or prolonged course of the pseudo-vascular syndrome. The pathogenesis of these disorders is discussed.

Partial remission of hemiplegia and somatoparaphrenia through vestibular stimulation in a case of unilateral neglect.

In a case of long lasting severe neglect resulting from a large right parieto-temporo-occipital infarct, vestibular stimulation produced a temporary reduction of the motor deficit and disappearance of the somatoparaphrenic delusion, in addition to the already reported improvement of extrapersonal and personal neglect and anosognosia. These data open new perspectives in the understanding of the neglect syndrome and of functional involvement of the parietal lobe in space representation.

Vertigo and upside down vision due to an infarct in the territory of the medial branch of the posterior inferior cerebellar artery caused by dissection of a vertebral artery.

A 48 year old woman developed an acute vestibular syndrome associated with upside down vision a few hours after minor cervical trauma. Magnetic resonance imaging showed an ischaemic lesion in the territory of the medial branch of the posterior inferior cerebellar artery. An arteriogram showed a dissection of the left extracranial vertebral artery.

Cryptic angioma in the trochlear nerve. Excision of the invaded portion and successful repair with an autologous graft: case report.

Cryptic angiomas, which are intrinsic to cranial nerves, are uncommon. Such lesions involving the trochlear nerve have not been previously described. The authors have therefore found it interesting to report a case fortuitously discovered in a patient with trigeminal neuralgia who underwent a fifth nerve microvascular decompression through the supracerebellar space. The angioma was not responsible for the neuralgia, but because of its potential risk of bleeding, the lesion was treated by resection of the trochlear nerve in its invaded portion. Then, the nerve was successfully repaired with an autograft harvested from the distal part of the sural nerve.

[Idiopathic cranial polyneuropathies].

A series of 43 cases with multiple cranial nerve deficits was collected between 1972 and 1990. No diagnosis was established in 15 cases. The facial and the trigeminal nerves were most frequently affected. In 10 cases, a monophasic course was observed usually with recovery. Recurrence was present in 5 cases. An inflammatory mechanism was likely in 10 cases. Nosological relations between these cases and either Bell's palsy (idiopathic facial paralysis) or Tolosa-Hunt's syndrome are discussed.

Korsakoff's syndrome as the initial presentation of multiple sclerosis.

A 37-year-old man presented with an acute amnestic syndrome of Korsakoff's type and an upper brain-stem oculomotor syndrome. After a moderate improvement with steroid therapy, he developed progressive behavioural changes due to a frontal lobe syndrome, in addition to motor and visual impairment. Memory performance was investigated on several occasions during an 11-year follow-up. Diagnosis of laboratory-supported definite multiple sclerosis was established and magnetic resonance imaging showed disseminated white matter lesions, especially in both medial temporal lobes. No other cause than multiple sclerosis was found for the amnestic syndrome. Among the rare cases of Korsakoff's syndrome in the course of multiple sclerosis, this is to our knowledge the first case in which a memory deficit was the initial manifestation of the disease.

Saccade metrics in multiple sclerosis: versional velocity disconjugacy as the best clue?

We studied the parameters (latency, amplitude, peak velocity) of horizontal saccades in 32 patients with multiple sclerosis (MS) and 20 healthy, age matched control subjects. Saccades were recorded by direct-current electro-oculography technique (EOG). The patients were divided in 2 groups according to the absence or the presence of clinical internuclear ophthalmoplegia (INO). In both groups, we found increased latency, hypometria and reduced velocity. The disconjugacy of saccades was measured by calculating the ratio of abduction and adduction peak velocities (the versional disconjugacy index: VDI). Though the absolute value of this index might be dependent on the recording technique, its variation is not. Interestingly, the VDI was significantly increased in the groups of MS patients without clinical INO, indicating a more severe slowing in adduction. We concluded that VDI may be a very useful index in detecting subtle disorders in saccades conjugacy.

P.O.E.M.S. syndrome with complete recovery after treatment of a solitary plasmocytoma.

The P.O.E.M.S. syndrome is a rare clinical entity that has been described mainly in Japan. It is characterized by a progressive polyneuropathy with raised CSF protein content, organomegaly, endocrinopathy, skin changes and plasma cell dyscrasia. We report a new documented case associated with a solitary plasmocytoma of the 12th thoracic vertebra. Immunopathological and ultrastructural studies of the peripheral nerve did not disclose any immune-specific changes. Surgery and radiation therapy of the plasmocytoma allowed a complete recovery, with a 5-year follow-up. This case report illustrates the need for serial full skeletal survey, including scintigraphy, in middle-aged patients with progressive polyneuropathy of obscure origin.

Homonymous horizontal sectoranopia: report of four cases.

Four cases of right homonymous horizontal sectoranopia are described. They were investigated with automatic static perimetry matched in three cases with Goldmann perimetry. In two cases--a wound of lateral sinus, a temporal surgically excised oligo-dendroglioma--neuroradiological investigations localised the visual pathways lesion to the optic radiations. In two other cases the lesions of vascular origin were less precise. In both of these there were ischaemic phenomena. In one of them the left anterior superficial sylvian territory was involved and in the other the left anterior choroidal artery territory was in question. This visual field pattern, less rare than was previously supposed, seems in some cases to correspond to retrogeniculate and varied topographic lesions.

Pituitary adenomas: automatic static perimetry and Goldmann perimetry. A comparative study of 345 visual field charts.

In a series of 81 cases of pituitary adenoma 345 charts of visual field performed with static automatic perimetry (AP) on the Vision Monitor and Goldmann perimetry (GP) were compared. Generally both methods were equivalent in the detection of chiasmal compression. The charts were divided into two groups: (A) 208 charts and (B) 137 charts according to the number of isoptres investigated: two (V4, 112) or three (V4, 112, 12). In group A the AP was more often altered than the GP, and the difference was statistically significant (p less than 0.001). In group B the GP seemed more effective, but the number of questionable cases was greater and the difference was not statistically significant. When the most internal isoptre of GP was outside the central 30 degrees, AP was more often abnormal (29%) than GP (2.2%), and the difference was statistically significant (chi 2, p less than 0.001). Within the central 30 degrees the GP seemed more often to be altered (23% of cases) than the AP (19.4%), but one-third of the cases were questionable. Within the central 30 degrees both techniques gave identical results and there was no statistically significant difference. The discrepancies between both static and kinetic techniques are an argument for their complementary use.

[Nuclear oculomotor nerve syndrome and ocular tilt reaction caused by mesencephalic hematoma].

A 78-year-old man had a midbrain hemorrhage, documented by CT scan and MRI, resulting in a mild cerebellar syndrome predominant on the left upper limb, lateropulsion, and a complex ocular motor syndrome. The latter was associated with right nuclear oculomotor nerve palsy, gaze paresis to the left for voluntary saccades, and a tonic ocular tilt reaction. Pathophysiological mechanisms are discussed.

[Causes of paralysis of the hypoglossal nerve. Apropos of 32 cases].

Thirty-two consecutive cases of hypoglossal nerve palsy (excluding syringomyelia and amyotrophic lateral sclerosis) collected between 1971 and 1987 were reviewed. The XIIth nerve palsy was clinically isolated in 8 cases, associated with other cranial nerve palsies in 16 cases and with long tracts involvement in 8 cases. Seventeen cases were related to tumours. Malignant tumours were predominant, especially middle and posterior fossa bone metastases. Carcinomatous meningitis and brainstem glioma were also found, as well as lymphoproliferative disorders and benign tumours such as chemodectoma and neurinoma. A vascular origin was established in 6 cases, related to vertebrobasilar infarct, truncular ischaemia and internal carotid dissection. The paralysis was consecutive to head or neck trauma in 4 cases and to various inflammatory processes in 4 other cases. The last case was caused by Chiari's malformation. To our knowledge, this is the first aetiological review of XIIth nerve palsy in the literature.
