title: Factors implicated for late presentations of gross congenital anomaly of the nervous system in a developing nation.
abstract: BACKGROUND
  Gross congenital lesions of the nervous system are obvious at birth and usually present early for management and corrective surgery. However in tropical and developing nations, late presentations are common.
  
  
  OBJECTIVE
  To determine the factors responsible for very late presentations of gross congenital lesions.
  
  
  METHODS
  We conducted a prospective study of all cases of congenital CNS anomalies that presented very late (>6 months after birth) to our neurosurgical clinic over an eight year period (2000-2008).
  
  
  RESULTS
  A total of 81 patients were seen during the study period. The age ranged from 6 months to 47 years. Hydrocephalus accounted for about half of the cases 37 (48.3%). The others were spina bifida 15 (18.5%), encephalocele 10 (12.4%), subgaleal inclusion dermoid cyst 7 (8.6%), and craniosynostosis 6 (7.4%), neurofibroma 4(4.9%), and anencephaly 2 (2.5%). Reasons given for late presentations were ignorance, poverty and in some the expectation that the baby would die. Other reasons for late presentation were that the patient was either about to start school or get married.
  
  
  CONCLUSIONS
  Late presentations of congenital CNS lesions are associated with many complications most of which could have been avoided with early medical treatment. Health education should include issues regarding congenital malformations delivered by trained experts.
