Abstract

A schwannoma of the aryepiglottic fold is an uncommon benign tumor. We report a rare case of a laryngeal schwannoma. The clinical, computed tomography (CT) and magnetic resonance imaging findings are presented. The tumor was located at the both aryepiglottic folds of the larynx. The CT scan revealed a well defined, delayed, heterogenously, target-like enhancing mass extending from the right aryepiglottic fold to the left aryepiglottic fold. The tumor was removed completely by laryngomicroscopic surgery (LMS). The diagnosis and treatment of this tumor are also discussed.

  Fig. 1 Schwannoma of the aryepiglottic folds in a 29-year-old woman. A-C. The axial (A), coronal (B), and sagittal (C) CT images showed a well-defined, heterogeneously enhancing mass (white arrow) that was intra-luminal protruding and broad-based at the bilateral aryepiglottic folds. D-G. On MRI, the mass (white arrow) showed slightly hyperintense signal intensity comparing to the adjacent hypoglossal muscles on the axial T1- (D) and coronal T2-weighted images (E) and heterogeneous enhancement on the gadolinium-enhanced axial (F) and coronal (G) T1-weighted images. H. Histology section shows Verocay bodies (black arrows) formed by palisading spindle-cell nuclei (H & E, ×100).
