A case of a ruptured metastatic aneurysm of choriocarcinoma is reported. The fourteen other cases of the literature are summarized. The pathological significance of this rare presentation of metastatic disease is discussed. The treatment of choice is defined as excision followed by chemotherapy and whole brain irradiation. The prognosis remains poor.
The authors present the results of the postoperative I.C.P. records in 35 patients. The results emphasize the relationship between the clinical grading and the degree of the intracranial pressure: 4/7 grades III (Hunt and Hess grading) and all the grades IV (4/4) had an abnormal intracranial pressure. The location of the aneurysm does not clearly appear as a significant factor of increased intracranial pressure in the postoperative period.

Mycotic intracranial aneurysms are of infectious origin and, even nowadays, their treatment remains controversial with advocates for either surgical or medical treatment. We present the case of a 58-year-old patient who was admitted to the hospital with a left hemiparesis due to a large right parietal haematoma. An angiogram demonstrated a small vascular malformation localized on a distal parietal branch of the right Sylvian artery. The patient was operated on and recovered well. Nevertheless, a control angiogram demonstrated the disappearance of the previous malformation but showed a new saccular aneurysm localized on the right rolandic artery. At the same time the patient became septic and the diagnosis of endocarditis complicated by mycotic aneurysm was confirmed. The patient was then medically treated with antibiotics for two months and several angiograms showed the progressive disappearance of this aneurysm. Different treatments of intracranial mycotic aneurysms are finally reviewed and a therapeutic approach is discussed.
Two cases of spinal cord compression by thoracic epidural cysts are reported. The first case, associated with a lipoma, is of a congenital type, while the second illustrates a rare mechanism of spinal cord compression caused by a post-traumatic cyst after stretching of the brachial plexus and tearing of the meningeal sheaths of nerve roots. Computed tomography of the spine is helpful in disclosing the cyst and associated malformation, particularly in congenital cases. The prognosis is good after removing the cyst and closing the fistula communicating with the subarachnoid space. Further surgical treatment may be required in complex congenital malformations.
The association of two aneurysms on the distal posteroinferior cerebellar artery with an arteriovenous malformation fed by the same artery is reported. A one-stage operation was performed. The other cases in the literature are analyzed with particular regard to the origin of the subarachnoid hemorrhage and the location of the aneurysms.
Two cases of meningiomas with metastasis are presented. The first case is typically a fibroblastic meningioma. After a local recurrence, dissemination occurs in the CSF with multiples localizations. The second case is a parasagittal meningioma of meningotheliomatous type. After two recurrences, a lymph node metastasis is discovered. Three modes of dissemination are known: through the blood vessels, the lymphatics or the CSF. The different spreads and mechanisms are discussed.
The case of a solitary cerebellar abscess in a 36-year-old Rwandese male is described. First it was considered to be tuberculosis, but at microscopal examination of the lesion after neurosurgical excision the true germ was found: Blastomyces dermatitidis. This solitary intracerebellar blastomycosis abscess is only the fifth case reported worldwide and the first in African medical annals.

An unusual case of traumatic aneurysm of the A-1 part of the anterior cerebral artery associated with a contralateral carotid-cavernous fistula is presented. Trapping of the fistula was carried out, and an attempt to repair the vessel wall was made. Thrombosis of the vessel occurred, but remained asymptomatic. Causes, physiopathology, and treatment of traumatic aneurysms are discussed.
Cerebellar gliomas are the most frequently occurring tumors of the central nervous system in children and adolescents, but glioblastomas are definitely rare in cerebellum before twenty years of age. Only two histologically proven cases have been published in the international literature (1,2). We describe one new case and give a review of the literature.

A case of tuberculous meningitis associated with cerebral tuberculomas, and resistant to antituberculous therapy is reported. Repeated injections of rifampin, administered through an intraventricular Ommaya drain, provided an effective control of the meningeal infection.
The authors describe a case of inferior red nucleus syndrome due to a solitary intramesencephalic metastasis from a glandular epithelioma of the prostate. They emphasize the rarity of cerebral metastases of prostatic origin, particularly at the level of the brain stem, and the exceptional features of a red nucleus syndrome originating from a tumour.

A patient with the clinical diagnosis of brain abcess presented with a CT brain scan showing an intracerebral hematoma. Subsequently bilateral spontaneous hyperdense lesions appeared. Autopsy showed the typical findings of viral encephalitis probably due to herpes simplex. It is stressed that the differential diagnosis of intracerebral hematoma includes viral encephalitis in the proper clinical setting.
