Metastatic Pancreatic Neuroendocrine Carcinoma Presenting as a Sphenoid Sinus Mass in a Juvenile

Primary neoplasms of the sphenoid sinus are rare. Instead, these lesions typically arise by local tumor extension from surrounding structures or are non-neoplastic in origin. Metastatic lesions are encountered even less frequently. We present a case of metastasis of pancreatic neuroendocrine carcinoma to the sphenoid sinus in an 18 year old male and to document this rare but potentially confusing radiologic diagnosis.
