CT and MR findings in 16 cases of primary neuroendocrine

Clinical imaging · Mar 2015

CT and MR findings in 16 cases of primary neuroendocrine carcinoma in the otolaryngeal region.

Primary neuroendocrine carcinoma (NEC) is a rare malignancy in the otolaryngeal region. Computed tomography and magnetic resonance imaging findings in 16 patients with primary otolaryngeal NECs were summarized. Most of tumors occurred in the sinonasal cavity (n=9; 56.3%), then supraglottis (n=3; 18.8%). ⋯ All lesions showed moderate to marked enhancement, but homogeneously in well-differentiated tumors while heterogeneously in most of poorly differentiated tumors. Most sinonasal tumors were poorly differentiated and invaded adjacent bones. Primary otolaryngeal NECs might have some distinct features related to their origin and differentiation.

AbstractPrimary neuroendocrine carcinoma (NEC) is a rare malignancy in the otolaryngeal region. Computed tomography and magnetic resonance imaging findings in 16 patients with primary otolaryngeal NECs were summarized. Most of tumors occurred in the sinonasal cavity (n=9; 56.3%), then supraglottis (n=3; 18.8%). All sinonasal and one hard palate tumors were ill defined, and the other tumors were well defined. All lesions showed moderate to marked enhancement, but homogeneously in well-differentiated tumors while heterogeneously in most of poorly differentiated tumors. Most sinonasal tumors were poorly differentiated and invaded adjacent bones. Primary otolaryngeal NECs might have some distinct features related to their origin and differentiation.Copyright © 2015 Elsevier Inc. All rights reserved.
