A 43 year old man presented with decreased sensitivity in the left side of the face and both upper limbs, and with upbeat nystagmus and skew deviation. MRI demonstrated a well defined lesion compatible with an infarct in the left side of the medulla, caudal and ventral to the vestibular nuclei, possibly involving the most caudal of the perihypoglossal… (More)
We report a case of intracerebral hemorrhage which occurred during a migraine in a 62 year-old woman who had migraine since the age of 20. The patient was normotensive. The angiograms were normal. Cerebral hemorrhage in migraine appears to be very rare: we found 6 reported cases that were compared with our own. The hypothesis of recirculation in an… (More)
Seventeen chronic cerebral infarcts were investigated by a highly sensitive, dedicated brain single photon emission computerized tomography system using 123I-isopropyl iodoamphetamine (IMP) and 133Xe. IMP uptake was measured 10 minutes, 2 hours, and 5 hours after injection, and regional cerebral blood flow was measured with 133Xe. In 4 cases a positron… (More)
Seventeen chronic cerebral Infarcts were investigated by a highly sensitive, dedicated brain single photon emission computerized tomography system using li3 I-isopropyl iodoamphetamine (IMP) and LU Xe. IMP uptake was measured 10 minutes, 2 hours, and 5 hours after injection, and regional cerebral blood flow was measured with 133 Xe. In 4 cases a positron… (More)
We report a of gelastic epilepsy. MRI showed a probable hamartoma in the diencephalic region.
We studied 18 patients with transient ischemic accidents (TIA) and normal CT scan during the first 24 hours. MRI was performed 9 days later on average. MRI revealed abnormalities in 10 patients (56 p. 100), but only 5 of them (27 p. 100) had lesions corresponding to TIAs, and in every case these were in the carotid territory. In the 7 patients with clinical… (More)
A 12 year-old boy was investigated for progressive deformity of the left foot developing over 2 years. The foot was hollow with equinus varus and claw toes. Signs of a lesion of left L5 and S1 roots were present and spina bifida at L5 was noted on X-rays. Magnetic resonance imaging (MRI) showed a tethered spinal cord associated with a lipoma at the level of… (More)
Among 4,538 neuroradiology cases gathered at the NOHC of the XV-XX, an oculomotor paralysis is the 3rd (37.65%) clinical circumstances justifying a computerized tomography (directional plane by the neuro-ocular plane or PNO). The interpretation of the investigations requires to index them in 7 groups of items, therefore a computerized access follows… (More)
A left ophthalmoplegia and right hemiplegia were due to thrombosis of an intracavernous aneurysm with occlusion of the left internal carotid artery. Ophthalmoplegia with contralateral hemiplegia is probably a rare syndrome. Thrombosis of an intracavernous aneurysm is probably a rare cause of occlusion of the internal carotid artery.
In 1 case of occlusion of the basilar artery and 1 case of occlusion of the left middle cerebral artery a CT Scan performed within 24 hours of onset showed a high density area corresponding to the segmental arterial occlusion. In both cases on repeat CT Scans 5 and 9 days after the onset the high density area had disappeared.
