[Evaluation of CT in the diagnosis of esthesioneuroblastoma].
OBJECTIVE
To assess the role of CT in the diagnosis, staging and post-treatment follow-up of esthesioneuroblastoma.


METHODS
Thirteen cases of pathologically comfirmed esthesioneuroblastoma were analysed retrospectively.


RESULTS
On preoperative check up, according to Kadish staging, no case was in stage A, 4 cases were in stage B, 7 in stage C. Tumor scans showed soft tissue density. In 3 cases, calcification was found inside of the tumor. In the 4 cases on scan and enhanced CT, the tumors were heterogeneously enhanced in 3. On enhanced CT, the tumor density was obviously higher than that of the surrounding soft tissue in 6 cases. Postoperative follow-up CT revealed tumor recurrence within 3 months to 2 years in 4 cases. Tumor invasion involved nasal cavity and ethmoid sinus(13 cases), maxillary sinus (12 cases), sphenoid sinus(10 cases), frontal sinus (2 cases), orbit (7 cases). Intracranial invasion occurred in 3 cases, and lymph node metastases in 4 cases.


CONCLUSIONS
CT is valuable in pre-operative staging and monitoring recurrence of esthesioneuroblastoma. Although esthesioneuroblastoma has characteristic CT features on enhancement and multiple invasions to neighboring structures, reliable diagnosis is dependent on pathological confirmation.
