“…However, the MRI appearance of this lesion was nonspecific as to a cause of the lesion. It is uncommon for MRI characteristics of a tumour to be completely pathognomonic; however, laryngeal neuroendocrine tumours in man have commonly been described as having the signal characteristics seen in this case, including isointensity to muscle in T1 weighted images, contrast enhancement and hyperintensity to muscle on T2 weighted images (Ebmeyer et al . 2009).…”

Summary A 13‐year‐old Quarter Horse mare was presented to the Ontario Veterinary College Teaching Hospital with chronic progressive respiratory noise and exercise intolerance. Severe respiratory stridor associated with a laryngeal mass was seen on upper airway endoscopy. Ultrasonography revealed an intra‐cartilagenous mass and allowed for a guided biopsy. Histological analysis of the mass characterised a neuroendocrine tumour and the mare was subjected to euthanasia due to the poor prognosis. Ultrasound examination was paramount in making the diagnosis and facilitating the biopsy. To our knowledge, neuroendocrine tumours have not previously been reported in the equine larynx.

“…On magnetic resonance imaging scans, the lesions appear isointense to slightly hyperintense in T1-weighted sequences, hyperintense in T2-weighted sequences and hyperintense with gadolinium enhancement [ 10 ]. Differential diagnosis includes laryngeal cysts, laryngoceles, adenomas, chondromas and malignant tumors [ 11 ].…”

Laryngeal schwannomas are rare, benign neurogenic tumors. They normally present as a slow-growing, encapsulated, submucosal mass in the supraglottic region. We describe a 20-year-old female presenting with a 2-year history of hoarseness and progressive worsening dyspnea. Fiberoptic laryngoscopy and computed tomography revealed a round, low-density submucosal mass at right false cord and arytenoepiglottic regions with glottic extension. Microlaryngoscopic biopsy and debulking for this solid tumor were performed without tracheostomy. Schwannoma was confirmed by histopathological study. However, rapidly worsening stridor occurred 2 weeks after the surgery. Fiberoptic laryngoscopy showed an exophytic tumor occupying the right hemilarynx with airway compromise. Definite complete excision of the tumor was performed by right vertical hemilaryngectomy. At 5-month follow-up, the laryngeal wound was clear without signs of recurrence. Rapid occurrence of airway obstruction after debulking and biopsy was demonstrated in this case. Vertical hemilaryngectomy was inevitable to cure this potentially life-threatening laryngeal schwannoma in this young female with postoperative serviceable voice.
