title: Lacrimal gland abscess presenting with preseptal cellulitis depicted on CT.
abstract: BACKGROUND
  Pyogenic lacrimal gland abscesses are uncommon and thus may not be immediately clinically recognized without a high index of suspicion.
  
  
  RESULTS
  We present two patients with preseptal cellulitis and characteristic low-attenuation fluid collections in the lacrimal glands demonstrated on computed tomography (CT).
  
  
  CONCLUSIONS
  Lacrimal gland abscesses should be considered when dacryoadenitis is refractory to medical treatment. Indeed, these cases highlight the value of prompt recognition of lacrimal abscess through ophthalmologic referral and the use of diagnostic imaging. Both patients were successfully treated via incision and drainage.
