title: Periorbital cellulitis, subgaleal abscess and superior sagittal sinus thrombosis: a rare combination of complications arising from unilateral frontal sinusitis.
abstract: BACKGROUND
  Subclinical infection of the sinuses can result in delayed diagnosis and unusual presenting complications.
  
  
  METHODS
  This paper describes the case of a 14-year-old boy with a rare combination of periorbital cellulitis, subgaleal abscess and superior sagittal sinus thrombosis following a late presentation of unilateral frontal sinusitis.
  
  
  RESULTS
  Following multiple surgical procedures, and antimicrobial and anticoagulation therapy, the patient made a full recovery.
  
  
  CONCLUSIONS
  Serious sinusitis complications still occur, and can do so in unusual combinations with minimal clinical signs. Systemic anticoagulation therapy is considered safe practice in the management of cerebral venous sinus thrombosis and may reduce morbidity and mortality.
