Abstract:
Differentiating osteoradionecrosis (ORN) from tumor recurrence is challenging. This report is rare documentation of false-positive F-FDG PET scan attributed to ORN in a patient previously treated for carcinoma of base of tongue (Ca BOT). Extraordinarily high F-FDG uptake was seen in right ramus (SUVmax, 17.4), left body mandible (SUVmax, 13.6) with left pleural deposits (SUVmax, 17.4). Tumor recurrence was suspected. Pleural fluid aspirate showed evidence of metastatic disease. However, CT-guided biopsy of mandibular lesions revealed necrotic tissue. Hence diagnosis of ORN was established. Patient was put on palliative chemotherapy. No mandibular recurrence was noted during 6-month follow-up period.

A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...
