Low-grade supratentorial astrocytomas and oligodendrogliomas in adults are uncommon tumors of the central nervous system. We analyzed retrospectively 23 patients with this type of neoplasia, who were operated on between 1986 and 2002. There were no post-operative deaths. The survival rate at 5 and 10 years post-surgery for the entire sample was 67 and 30%(More)

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)
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)

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)
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)
OBJECTIVE To observe whether microsurgical removal of medullary lipomas and untethering of the medulla is a safe and efficient procedure. METHOD A retrospective study was carried out on 38 patients with medullary lipomas associated with spinal dysraphism who underwent operations between January 1986 and January 2008, at the Neurosurgery Department of the(More)
