Presentation
Neck pain, hoarseness. Laryngoscopic results: both vocal cords with preserved mobility; thickening and irregular bulging of the Left true vocal cord. Biopsy was performed
Patient Data
Irregular thickening of the free edge of the left true vocal cord, with preserved para-glottic space.
Irregular bulging of the free edge of the left vocal cord (white arrow).
Preserved fat hypodensity of the paraglottic space (black arrowhead).
Histopathological diagnosis (translation from the original paper):
Incisional biopsy specimen from within the left true vocal cord.
Results: multiple fragments of about 10 mm maximum diameter resulting of invasive squamous carcinoma of high grade (G3).
Case Discussion
This is a retrospective study and CT imaging was compared to histopathological diagnosis.
According to AJCC prognostic stage grouping 2018, this primary tumor of glottic was considered T1a and stage I because the tumor invaded only one vocal cord with normal mobility.
CT study confirmed the laryngoscopic assessment; there was a good correlation between vocal cord preserved mobility at laryngoscopy and PGS-sparing on the CT; moreover, good correlation of the neoplastic extension in the axial plane with both modalities resulted.
If there had been both vocal cords involvement with normal mobility and PGS sparing at CT scan, a T1b stage would result.
Radiotherapy planning was considered.
