CASE HISTORY / CLINIC:
52 year old heavy smoker with severe swallowing difficulties.

FINDINGS:
The post contrast axial CT image of the larynx demonstrates an extensive, mainly left-sided mass on both sides of the larynx with distinct inhomogeneous contrast enhancement. The mass can be seen all around laryngeal skeleton. The lumen of the larynx is slightly displaced to the left.
The sagittal reconstruction image (top right image) excellently demonstrates the cranio-caudal spread of the tumor that extends from the oropharynx right down to the larynx. The coronal reconstruction images (images below) also demonstrate the spread of the tumor; the lower right picture shows the growth all around of the laryngeal skeleton. The lower left picture also shows lymph node metastases.


DIAGNOSIS:
Extensive hypopharynx-larynx carcinoma with pathological lymph nodes.


DIFFERENTIAL DIAGNOSIS:
Other malignant tumors with origin in the hypopharynx or larynx.
