RESUMO
Coronal CT is the imaging modality of choice in patients with sinus diseases. CT provides and initial screening of these patients and can display anatomic cuases of recurrent sinusitis when they exist, CT is essential for planning surgery, and it provides an operative road map for subsequent FESS. Coronal sinus CT scan of 200 candiates of FESS reviewed for the major inflammatory patterns and anatomic variations which may attribute to inflammatory disease. Five recurring patterns of inflammation, including infundibular 6%, ostiomeatal unit [OMU] 34%, sphenoethmoidal recess [SER] 24%, polyposies 16%, and sporadic 32% were seen. Some cases have more than one pattern. Anatomic variations included septal deviation [40%], Chonca bullosa [24%], paradoxical middle turbinate [4%], atelectatic uncinate process [6%], Haller cell [12%], giant ethmoid bulla [8%], agger nasi cell [8%], onodi cells [2%]. Higher incidence of more severe patterns and anatomic variations in our study may be due to socioeconomic states of patients, study on surgical cases, and that our center is a referral center
RESUMO
To review all cases of esthesioneuroblastoma in Qaem Hospital from 1990 to 2004 with respect to Clinical findings image studies, staging, grading, histopathological and prognostication. Possible cases of esthesioneuroblastoma were retrieved from Neurosurgery, Otorhinolaryngology And Pathology departments. Patients were included on the basis of review of their files or pathology reports. Thirteen possible cases were retrieved. One case was excluded because of no documented pathology. Esthesioneuroblastoma is a malignant neuroendocrine tumor originating in the olfactory mucosa. It is a small blue cell neoplasm with a characteristic lobular architecture. The tumours were staged according to Kadish staging system and Kaplan-Meier survival analysis was used to identify prognostic factors. The Kadish staging system was able to group the patients into prognostically relevant groups. Intracranial involvement and metastases at the time of diagnosis were found to be poor prognostic factors
