Management of spina bifida cystica in Zaria, Nigeria is selective. Over a period of 11 years, 77 children with this defect, 54 meningocoeles and 23 myelomeningocoeles, 66 (86%) situated in the lumbosacral region, were treated operatively. Forty-two (55%) had surgery in the neonatal period and 91% within 6 months of birth. Postoperative complications occurred in 19 of 68 patients (28%), including mild hydrocephalus, which resolved spontaneously (six, 9%), wound infection (six, 9%), leakage of cerebrospinal fluid (four, 6%) and meningitis (three, 4%). Mortality was 3% from both meningitis and cardiac arrest. Of 32 patients followed up for 3-5 years, 20 with meningocoeles were normal. Of 12 with myelomeningocoele, four had varying degrees of lower limb weakness, three double incontinence, two faecal incontinence, two had progressive hydrocephalus plus paralysis and double incontinence, and one had urinary incontinence. Therefore, 38% were functionally disabled and could not be adequately rehabilitated owing to poor facilities. While management of spina bifida cystica is more aggressive now in most developed countries, ours remains selective due to difficulty with multidisciplinary care and rehabilitation. Even with our selective management, the care of patients with functional handicap remains a challenge.

Neurofibroma of the scalp are mostly multiple as part of neurofibromatosis or other phakomatosis. De novo solitary types are less common and rarely erode the skull, unlike the intracranial counterpart. Skull erosion has been reported in adults with longstanding plexiform neurofibromas. We report a giant neurofibroma on the scalp of a five-year-old boy, managed in our center. Although this condition is a rare entity, it should be anticipated and the treatment strategy should include repair of the skull defect.

The central nervous system is a very delicate and vulnerable organ which enjoys protection by layers of coverings. It is described as an immunological vacuum, and when afflicted by infections the outcome is most often devastating. Factors leading to compromise of the host defense play a major role in establishing neurosurgical infections. A number of such factors can either be avoided or minimized. Over the past decades, these infections have been fatal. However, more recently, the advent of newer more effective antibiotics, improved bacteriological studies, advanced imaging facilities, and meticulous surgical techniques have turned around the outcomes. This article will review infections of the central nervous system of neurosurgical significance.
