title: True-FISP MRI in diagnosis of postoperative hernia recurrence: a brief report.
abstract: BACKGROUND
  A 24-year-old man underwent laparoscopic mesh repair of a right direct inguinal hernia which had recurred after previous surgery 3 months previously. A large swelling was noted in the right groin 4 h postoperatively, which was reduced initially but recurred within 24 h. A differential diagnosis of postoperative recurrence versus hematoma was considered, and patient was referred for imaging.
  
  
  METHODS
  The patient was imaged using different modalities including B-mode ultrasonography, computed tomography (CT) of the pelvis, and True-FISP magnetic resonance imaging (true imaging with steady-state precession MRI).
  
  
  RESULTS
  Initial focused ultrasound (US) [corrected] was suggestive of but equivocal for recurrence. Subsequent non-contrast CT of the region followed by rapid sequence (true-FISP) MRI confirmed the presence of bowel in the inguinal canal.
  
  
  CONCLUSIONS
  Imaging has a role in the diagnosis of postoperative hernia recurrence in cases where there is a clinical diagnostic dilemma, especially MRI using true-FISP sequence, which is acquired in seconds, is a non-ionising radiation modality and does not have inter operator variability.
