Dynamic Scintigraphy With SPECT-CT of Postoperative Salivary Leak

摘要

This 65 year-old woman, 1 month postoperative after maxillary sinus carcinoma (pT4N0cM0) excision and reconstruction, presented with significant left facial clear fluid wound leakage. A salivary or cerebrospinal leakage was suspected. Fluid analysis, CT, and MRI were noncontributory. Dynamic salivary scintigraphy with SPECT-CT allowed for the detection and localization of the leakage from the left parotid gland. Radioactive dose rate of the wound bandage was 50 Sv/h compared with 0.05 Sv/h for background and confirmed the diagnosis. Left total parotidectomy resulted in resolution.
