8y MC Golden Retriever. Previous endoscopy (1 week prior) with laryngeal biopsy resulted in a hematoma. A large, well‐circumscribed
mass that is hypointense to muscle on T1 sequences and hyperintense to muscle on T2, PD, and FLAIR sequences is present in the right
cranioventral cervical region adjacent to the larynx (a: arrows). There is a thin, peripheral rim of enhancement on contrast‐enhanced
images (d: arrowhead). The mass partially suppresses on the FLAIR image (e).
