PURPOSE: This study was undertaken to collect information on the incidence and distribution of acute, non-traumatic conditions of the neck at our emergency radiology department and to review the literature about this topic. MATERIALS AND METHODS: We retrospectively reviewed 143 consecutive patients who underwent neck computed tomography (CT) for non-traumatic emergencies between 1 December 2008 and 31 December 2012. For each of the conditions identified, we defined the overall incidence, the incidence based on the site, gender, average age and age range. RESULTS: Computed tomography examination was positive in 125 out of 143 patients (87.4%), 74 men and 51 women, with an average age of 51.1 years, aged between 10 and 90 years. We found 79 inflammatory/infectious conditions (63.2% of positive cases, 55.2% of total cases), 46 men and 33 women, with an average age of 47 years. Computed tomography revealed 26 newly found tumours (20.8/18.2%), 19 men and 7 women, with an average age of 68.5 years, aged between 49 and 97 years. In 20 cases, 9 men and 11 women, with an average age of 57.3 years, aged between 21 and 90 years, we diagnosed other acute conditions: six cases of foreign body ingestion (4.8/4.2%), five benign swellings (4/3.5%), five cases of vascular disorders (4/3.5%), and four cases of oedema of the larynx (3.2/2.8 %). CONCLUSIONS: Our study of emergency CT of non-traumatic conditions of the neck fundamentally revealed infectious/inflammatory diseases and newly found neoplasms.
