Squamous cell vocal cord cancer with possible recurrence to cervical esophagus region. There are post-treatment findings in the upper neck, including diffuse pharyngeal and supraglottic edema and fatty signal alteration in the cervical spine bone marrow related to radiation therapy. There is an ill-defined mass in the left tracheoesophageal groove that measures approximately 30 mm in width. There is otherwise no evidence of significant lymphadenopathy elsewhere in the neck. However, there is a T1 hypointense and T2 hyperintense submucosal nodule deep to the right palatine tonsil that measures approximately 10 mm in diameter.
1. An incompletely characterized mass in the left tracheoesophageal groove that measures up to approximately 30 mm with corresponding hypermetabolism on the prior PET likely represents locoregionally recurrent squamous cell carcinoma. Aside from post-treatment edema, no measurable tumor is identified within the larynx, although the assessment is limited by the lack of intravenous contrast.2. An incompletely characterized submucosal nodule deep to the right palatine tonsil that measures approximately 10 mm in diameter may represent a minor salivary gland neoplasm for example.
