[Lipoma of the corpus callosum. 3 case reports and review of the literature].

Lipoma of the corpus callosum is a rare congenital intracranial tumor. Although only 153 cases had been reported as of March 1992, the incidence of this tumor is underestimated (some cases are unpublished and others are asymptomatic). Three cases of lipoma of the corpus callosum diagnosed in children are reported herein. These tumors may be either discovered fortuitously in an asymptomatic patient or responsible for manifestations of which the most common are seizures, headache, and mental disorders. Diagnosis rests on imaging techniques. The main investigation is computed tomography which discloses a mass composed of fat, with or without peripheral calcifications, and also identifies any other malformations such as dysgenesis of the corpus callosum.

[Osteoid osteoma of the spine. Radiological study of 21 cases].

Spinal osteoid osteomas are rare. We report 21 cases, that have been studied and treated since 1985. The tumor affects young people, who are less than 25 years old. The pain is the most common sign. Diagnosis is difficult, but can be made by radiology. X ray sometimes enables to suspect the diagnosis. Scintigraphy shows a focus hyperfixation more suggestive. Computed tomography enables the diagnosis by showing a bony lacuna surrounded by osteosclerosis. Moreover, computed tomography localizes very well the nidus of the osteoid osteoma, and guides the surgical treatment. Since computed tomography, other techniques like angiography and tomography are less used for diagnosis.

[Chordoma of the base of skull. Apropos of 3 cases].

The authors report 3 cases of skull base chordomas. In 2 cases, skull radiographies and computed tomography found lytic lesions of sphenoid and clivus, with calcifications into the tumors. In the third case, radiological findings suggest a naso pharynx tumor.

[Cerebral miliary tuberculosis. Apropos of 5 cases and review of the literature].

The authors report 5 cases of cerebral miliary tuberculosis studied by computerized tomography and review 5 cases of the literature. Computerized tomography can see very small tuberculomas, of several millimeters. Chest miliary tuberculosis is found in all their cases, and 3 of the 5 cases of the other authors. Because of the discretion of neurological signs and the association with chest miliary, we suggest to make a computed tomography of brain of all patients who have chest miliary tuberculosis despite the absence of neurological signs and we think that we will find out other cases of brain miliary tuberculosis.

[Neurinomas of the trigeminal nerve in neurofibromatosis. Apropos of two cases and review of the literature].

We report two cases of trigeminal neuroma in patients with Von Recklinghausen neurofibromatosis (NF1). Despite the high frequency of intracranial neuroma in neurofibromatosis, the localization on the fifth cranial nerve is an uncommon findings. In our two cases, neuromas were asymptomatic clinically and electrophysiologically, but computed tomography showed a small nodular lesion in the cerebellopontine cistern, independent of the seventh and eight nerve and which can only correspond to the fifth nerve. MR imaging very clearly demonstrates intracranial neuromas of all cranial nerves.

[Hemiballism. Description of a clinical case in childhood].

Biballism is an infrequent hyperkinetic disorder characterized by involuntary, intermittent, violent, uncontrollable contractions of the proximal muscles of the limbs. Biballism is classically ascribed to a lesion in the controlateral subthalamic nucleus or its connections but other causes have been reported. These include infections (bacterial, viral parasitic), cerebrovascular lesions, tumors, toxics, and systemic disease (systemic lupus erythematosus). Although poorly understood, the pathophysiology of hemiballism is widely believed to involve hyperactivity of the dopaminergic system. The prognosis of these abnormal movements, formerly poor, has been improved by the use of neuroleptics and drugs acting on the different neurotransmitter systems. A unique case of biballism at resolution of a febrile coma in a 4 1/2 year old is reported. The EEG showed diffuse slow waves. A hyperdense lesion was visible in the right thalamic region on the cerebral CT scan. The magnitude of the abnormal movements decreased under haloperidol. The etiology of this case of biballism is discussed.

[2 cases of vascular syndrome of the cranial nerves of ischemic origin].

The authors report the cases of two patients who had sudden unilateral alternating and regressive attacks of the cranial nerves. The first patient, a 63 year old diabetic woman, suffered regressive paralysis of the right third nerve, followed two months later by paresthesia of the same side of the face, accompanied by difficulty in swallowing and dysarthria. Six months later, she developed a right facial paralysis while pharyngeal and lingual involvement entirely disappeared. Right carotid angiography revealed stenosis of the middle meningeal artery. Nine months later she developed left-sided ophthalmoplegia followed by a homolateral facial paralysis. The second patient, a 24 year old woman, developed homolateral regressive attacks of the II, V, VII and VIIb, and VIII nerves during recovery from herpes zoster of the right geniculate ganglion. Doppler studies showed inversion of the flow in the right ophthalmic artery. The pathogenesis of these multiple paralyses of the cranial nerves is discussed, a possible cause being ischaemic attacks of the vascular territories of the cranial nerves.

[Cardiac failure caused by arteriovenous malformation in the area of Galen's vein. Treatment by endovascular embolization].

The authors report a case, in a 7-month-old girl, of cerebral arteriovenous malformation with a vein of Galen ectasia, complicated by a congestive heart failure and hydrocephalus. The clinical diagnosis was carried out by fontanelle auscultation and confirmed by: cerebral echography. Döppler exploration, computerized tomography and cerebral angiography. A cerebral embolization permitted reduction of cardiac insufficiency and stabilisation of the hydrocephalus.

Intracranial and orbital hydatid cysts.

Parasitic diseases involving brain and orbit are relatively rare in Tunisia; the most frequently encountered is the hydatid cyst, 55 examples of which were seen since CT scanning was introduced into Tunisia 2 years ago. Various aspects of the intracerebral and orbital hydatid cysts are reported and a tentative classification is made based on characteristics revealed by CT.

Transsphenoidal encephalocele associated with agenesis of corpus callosum: value of metrizamide computed cisternography.

Transsphenoidal encephaloceles are rare congenital malformations that are classified among the medial dysraphias and that are therefore associated with an agenesis of the corpus callosum. Clinically, the diagnosis is difficult, but hypertelorism and weakening eyesight should be of suggestive value. Diagnosis is basically radiological. In the past, it was founded on roentgenography, tomography of the base of the skull, pneumoencephalography, and angiography when necessary. Today, metrizamide computed cisternography using axial transverse and coronal sections, supplemented by sagittal reconstructions, allows for a complete examination of bony, meningeal, and cerebral abnormalities.
