title: Choledochal cyst: a case report and review of literature.
abstract: BACKGROUND
  We present our first experience in managing a case of choledochal cyst in a two and half year old girl highlighting the difficulties in the management together with a review of literature.
  
  
  METHODS
  A two and half year old girl presented to the University of Maiduguri Teaching Hospital. A pertinent clinical evaluation with abdominal ultrasound allowed accurate pre-operative diagnosis.
  
  
  RESULTS
  A young girl with a right hypochondrial mass confirmed as choledochal cyst by ultrasound scans. Haematological parameters were normal but deranged clotting profiles were corrected with vitamin-K injection before surgical drainage.
  
  
  CONCLUSIONS
  High index of suspicion with abdominal ultrasound scan allowed accurate pre-operative diagnosis of choledochal cyst that was successfully managed by surgical drainage, when attempted dissection of cyst wall for excision failed.
