title: Delayed Absorption of Oxidized Cellulose (Surgicel) in Post-Thyroidectomy Patients.
abstract: Delayed absorption of oxidized cellulose (Surgicel; Johnson & Johnson, New Brunswick, NJ) may mimic a pseudoabscess or a recurrent mass on sonography after tumor surgery. Here we present 3 cases of thyroidectomy in which Surgicel was still apparent on sonography after 26 to 47 months of follow-up. We show sonographic findings and discuss the utility of sonography for diagnosis of delayed absorption of Surgicel in post-thyroidectomy patients.
