BACKGROUND Despite advances in neuroimaging and neurosurgical care, spinal abscess remains a challenging problem with mortality rates ranging from 4.6% to 31% in recent series. METHODS Between January 1986 and December 2003, 24 patients with spinal epidural abscess were treated. Seventeen were men and 7 were women at the average age of 47.5 years.(More)
Intracranial hemorrhage due to arteriovenous malformation or intracranial aneurysms is a rare but grave complication of pregnancy. We analyse 15 cases. Among these, aneurysms ruptures were responsible for the bleeding in 5 instances. Arteriovenous malformation was diagnosed in other 6 patients. The maternal and fetal mortality was 20% and 33% respectively.(More)
The occurrence of brain tumours during pregnancy is unusual, when this happen jeopardises the lives of both the mother and infant. This article aims at identifying the best medical management to be followed for a pregnant patient harbouring a brain tumour. The records of 10 patients with brain tumours diagnosed during pregnancy were retrospectively(More)
BACKGROUND The aim of this paper is to report on our surgical strategy and technique and to identify the best management for intracranial dermoids and epidermoids tumors (IDETs). METHODS We retrospectively reviewed 33 consecutive patients (14 males and 19 females; mean age at surgery, 37.9 years) with pathologically confirmed IDETs who underwent surgical(More)
BACKGROUND The occurrence of a brain tumor or intracranial vascular lesion during pregnancy is a rare event, but when it happens, it jeopardizes the lives of both the mother and infant. It also creates challenges of a neurosurgical, obstetric, and ethical nature. A multidisciplinary approach should be used for their care. METHODS Between 1986 and 2015, 12(More)
Objective To describe a unique operative strategy, instead the classical pterional approach, and to analyses it safety and effectiveness for removal of anterior cranial fossa meningiomas. Method We identify 38 patients with tuberculum sellae and olphactory groove meningiomas operated between 1986 and 2013. Medical charts, operative reports, imaging studies(More)
OBJECTIVE Observe whether a microsurgical gross total removal (GTR) of a spinal nerve sheath tumors (SNSTs) is safe and decreases the tumor recurrence. METHOD We identify 30 patients with 44 SNSTs. RESULTS We operated upon 15 males and 15 females patients; mean age 40 years. GTR was achieved in 29 (96.6%) instances. Surgical mortality was 3.3% and the(More)
OBJECTIVE It was to observe whether a microsurgical gross total removal (GTR) of a parasagittal meningioma (PSM) outside the sinus is a safe and efficient procedure. METHOD We identify 58 parasagittal meningiomas patients. Medical charts, operative reports, imaging studies and clinical follow-up evaluations were reviewed. RESULTS GTR of the mass was(More)
BACKGROUND Despite the development of microsurgery and cranial base techniques, the surgical management of Foramen Magnum Meningiomas (FMM) continues to be a technical challenge to neurosurgeons. Controversy concerning the utility of systematic condyle drilling for approaching FMM has been raised. Our aim was to describe the surgical technique, analyze its(More)
BACKGROUND To compare the survival of glioblastoma multiforme (GBM) patients operated on at public hospital with that of patients operated on at the private hospitals. METHOD We carried out a retrospective analysis of the patients' medical records, the surgical reports and the pre- and post-operative images of patients with a histopathological confirmed(More)
