CASE
HISTORY / CLINIC:
Female with increasing obstruction of the left nasal passage. Discharge of partially
purulent secretion from the left nostril. A round tumor that almost entirely
occludes the left main nasal cavity was found during endoscopy.
FINDINGS:
The
coronal CT scans (bony and soft-tissue windows) without contrast enhancement
demonstrate a large hypodense
mass lesion in the left nasal cavity. The mass extends to the maxillary
sinus and ethmoidal cells and borders cranially on the lamina
cribrosa. One can not judge with certainty if the mass spreads intracranially
or extends to the left orbital cone.
DIAGNOSIS:
Leiomyosarcoma
in the left main nasal cavity and ethmoidal cells on the left.
DIFFERENTIAL
DIAGNOSIS:
Other
malignant or benign tumors in the main nasal cavity.
