title: Atypical Isolated Infections of the Infratemporal Fossa: A Diagnostic Challenge.
abstract: BACKGROUND
  Atypical infratemporal fossa infections are rare and potentially fatal.
  
  
  METHODS
  A case of an aspergillosis localized in the infratemporal fossa and another case of tuberculosis of the infratemporal fossa originating from the maxillary sinus, is described. The first patient was immunocompromised and showed symptoms of facial numbness; whereas the other was an immunocompetent man who complained of trigeminal neuralgia type pain. It was difficult to differentiate between infection and tumour despite the utilization of computed tomography scans and magnetic resonance imaging.
  
  
  CONCLUSIONS
  These cases illustrate the need for a high index of suspicion; in addition to endoscopic confirmation and histopathology to establish precise diagnosis and early intervention.
