"Pseudotumoral" cystic cerebellar infarction with slow evolution.

A 63-year-old female patient presented with cerebellovestibular symptoms and posterior headaches. The onset of the symptoms was sudden, and the neurological condition slowly worsened over a 5-month period. It was found that she suffered from a cystic infarction of the cerebellar lobe, with subsequent hydrocephalus. This case and two others discovered in the literature argue for the recognition of a slowly evolving, cystic form of cerebellar infarction that calls for a direct surgical approach.

[Multifocal infarction of the basilar trunk region. Persistence of a trigeminal artery].

A multifocal haemorrhagic infarction of the basilar artery territory, linked to the persistence of a trigeminal artery is reported. This was associated to hypoplasia of the basilar artery and of the posterior communicating arteries. The trigeminal artery supplied most of the distal part of the basilar territory. At post mortem there was no arterial occlusion and the infarction probably resulted from embolism from the heart or from the carotid artery.

[Ocular and head movements in infarctions of the thalamic region].

Oculomotor disorders in 22 infarctions in the thalamic region are recorded. Clinical examination and electro-oculography (17 cases) showed that paramedian thalamo-subthalamic lesions were responsible for clear deficits: upgaze paralysis and in some cases downgaze paralysis, partial paresis of the oculomotor nerve, deficits of lateral eye movements, myosis, paralysis of head flexion combined with downgaze paralysis. Postero-median choroid artery infarction was associated with upgaze paresis, slight deficit of lateral eye movements and myosis. Postero-lateral choroid artery infarction resulted in a partial visual field defect and in some cases, a contralateral hypometria; myosis was slight and inconstant. Infarctions of the internal capsule (anterior choroid artery, deep branches of the middle cerebral artery) were associated with a deficit of contralateral saccades. Ocular pursuit, when possible, was often saccadic, whatever the site of the infarction. This prevailed with gaze towards the lesion side.

[Cystic meningioma. 3 cases].

The association of a meningioma and an arachnoid cyst is one of the many association of cyst and meningioma. The diagnosis could be difficult by CT scan. We report three cases of parameningiomal cysts and discuss their different mechanism of formation before stressing practical problems.

[Postoperative aneurysm of the superficial temporal artery].

An aneurysm of the superficial artery, developing after surgical removal of a frontal meningioma is described. This case shows an other topographic possibility to post operatory aneurysm, mainly developed on the intracranial internal carotid artery or her branches.

[Hematomas of the cerebellum and tumors. 3 cases].

Three cerebellar hematomas induced by a tumor are reported. A metastasis was present in two cases, but the lesion was unique on CT scan, vertebral angiography did not reveal abnormal vessels, and general investigations were normal. The third case was a medulloblastoma. The first two patients were treated medically or with ventricular shunting. In both cases the primary tumor was lately discovered. These cases show that a CT scan follow up is necessary when the patient is not operated, and a pathological examination of the hematoma must be done where there has been surgical intervention.

[Chiasmatic tuberculoma. 2 cases].

The authors report two cases of chiasmatic tuberculomas. They emphasize that diagnosis is still difficult despite CT scan if a picture of tuberculous meningitis is lacking. Surgical approach may be justified when diagnosis remains uncertain, especially as tuberculoma is sometimes responsible for recurrent meningitis.

Spinal dysraphia and elongated spinal cord in adults.

Spinal dysraphia with stretching of the spinal cord is usually diagnosed in the adolescent or young-adult patient. Two types of the condition are distinguished: a stretched spinal cord with an intradural lipoma, and a stretched spinal cord with both an intra- and extradural lipoma. The pathogenesis of the condition and mechanical role of the lipoma and the late appearing neurological signs are presented.

[Post-traumatic retrograde amnesia].

A case of post traumatic retrograde amnesia is described. The patient presented after an initial coma a global amnesia, but the fixation deficit rapidly disappeared, and a severe retrograde amnesia dating back to childhood experience and learning remained the main symptom. Amnesia for remote events was associated with didactic memory deficit and, at a lesser degree, with a verbal memory deficit. Recovery of fixation allowed a progressive relearning. This pattern of impairment was recently related to mesencephalic lesions, but we think that the role of temporal lobe involvement cannot be neglected.

Intradural rupture of lumbar intervertebral disc: report of three cases with review of the literature.

The intradural herniated disc is a rare complication of disc herniation. A study of the literature shows that this location is often responsible for severe neurological deficit with loss of sphincter control and a complete block shown on the myelogram. We report three cases to demonstrate the radioclinical interpretation of intradural herniated disc and the possibility of definite and misleading symptoms.

[Alternating oblique deviation of the gaze. 3 cases].

Three cases of alternating skew deviation of gaze are reported. In two patients, it was associated with oculomotor disorders suggestive of a medial mesencephalic lesion. CT scan showed 3rd ventricule abnormalities accounting for the mesencephalic involvement. The third patient had a tuberculous meningo-encephalitis with basal symptoms. The pathophysiological mechanisms of the vertical interocular divergence is discussed. It was probably related to a bilateral disorder of the superior recti and an overaction of the inferior obliques. It suggested a medial supranuclear dysfunction.

[Parietal multilocular arachnoid cysts in adults. 2 cases].

Two cases of multiloculated arachnoid cysts of the parietal area are discovered at the ages of 57 and 69. The terrain, the situation and the morphology, the evolution, distinguish these lesions from the more classic cysts of the sylvian fissure. Their pathophysiology is discussed anatomically, these cysts are not far from the post traumatic ones, developing in childhood.
