[Presentation of a cavernous angioma with an oculomotor nuclear syndrome: a case report].

INTRODUCTION: The nuclear syndrome of the oculomotor nerve, first described in 1981, is characterized by ipsilateral third nerve palsy and elevation paresis of the contralateral eye. CASE REPORT: A 59-year-old man suddenly developed diplopia and headache. Neurological examination showed nuclear ophthalmoplegia of the left third nerve without any other neurological abnormality. MRI findings demonstrated a typical, popcorn-like, smoothly circumscribed left posterior lesion. Surgical resection was not performed because of the deep localization. Spontaneous bleeding developed. CONCLUSION: This neuro-ophthalmological complication of a cavernous angioma, as seen in our patient, has rarely been described in the literature. The clinical presentation and anatomic elements of the nuclear oculomotor syndrome are discussed. This exceptional localization provides a useful illustration of anatomoclinical correlations.

[Imaging of cerebrotendinous xanthomatosis].

Cerebrotendinous xanthomatosis is a rare lipid storage disorder due tocaused by an autosomal recessive inherited defect of the hepatic mitochondrial sterol 27 hydroxylase. It's characterized by accumulation of cholestanol and cholesterol in many tissues, in particular tendons and brain, with tendon xanthomas, juvenile cataracts, and neurological abnormalities. MR imaging showed typical bilateral and symmetrical involvement of the dentate nuclei. Early and long- term treatment may improve neurologic function. The authors present a case of cerebrotendinous xanthomatosis and describe ultrasound, computed tomography, and magnetic resonance findings.

[Balò's concentric sclerosis in a North-African patient].

INTRODUCTION: Balo's concentric sclerosis is a rare variant of multiple sclerosis described by Balo in 1928. It is characterized by alternating rings of demyelination and spared myelin. CASE REPORT: We report a case of Balo's concentric sclerosis diagnosed by the typical MRI findings of concentric rings of demyelination. Medullar and brain localisation were found and clinical course was good under intravenous corticosteroids. CONCLUSION: MRI provides the best diagnostic information for Balo's concentric sclerosis, allowing early diagnosis and treatment.

[Dyke-Davidoff-Masson syndrome: a report of two cases].

Dyke-Davidoff-Masson syndrome is a condition characterized by seizures, facial asymmetry, contralateral hemiplegia or hemiparesis and mental retardation. We report the clinical and imaging features in two patients with epilepsy revealing a Dyke-Davidoff-Masson syndrome. Brain MRI showed unilateral loss of cerebral volume with hypertrophy and hyperpneumatization of the paranasal sinuses and mastoid cells. Ipsilateral fronto-parietal polymicrogyria was present in one patient.

[Cerebral tuberculomas].

We report eight cases of brain tuberculoma. The clinical presentation was polymorphous: partial epilepsy (n=4), headache (n=3), hemiplegia (n=1), meningitis (n=1), cerebellar syndrome (n=1). Six patients also had pulmonary tuberculosis, one had tuberculosis of the genital organs, and one had HIV co-infection. The brain CT scan and MRI were highly contributive to diagnosis and follow-up. Despite good compliance with an anti-tuberculosis regimen for at least 14 months, the course was favorable in only six patients. Adjunction of corticosteroids led to radiological improvement. Assessment of cell immunity demonstrated a diminished immunomodulator ratio. Cerebral tuberculoma should be searched for in patients with unexplained neurological manifestations and several intracerebral lesions, particularly if pulmonary or visceral tuberculosis and/or immunodepression is part of the clinical picture.
