Magnetic resonance imaging suggested tumor recurrence; however, gadolinium-enhanced imaging was not performed because of the patient\u2019s known gadolinium allergy. Histopathological examination revealed xanthogranulomatous inflammation and a multinucleated giant-cell reaction to the suture material, without evidence of neoplastic recurrence.<\/jats:p>\n
