    ABSTRACT: Objective To assess the diagnostic certainty of CT images to identify regional spread of head and neck tumours. Patients and method A CT study was performed on 86 patients with neoplasms in the larynx and/or pharynx. After this, surgical dissection was performed for 142 neck sides. In the imaging study the following parameters were considered for all patients before suspecting malignant nodes: size of adenopathy bigger than 10-11 mm, irregular borders, central necrosis, spherical shape, capsular enhancement and presence of groups with three or more lymphadenopathies. Results 48.5 % of dissections were N+. Sensitivity and specificity for physical examination were 59 % and 82 %, respectively, against 73 % and 86 % for CT. Lymph node necrosis was the pattern with the greatest sensitivity and specificity (35.8 % and 100 %, respectively) and its accuracy was 69.7 %. Accuracy was 60.5 % for spherical shape, 59.8% for node size, and between 54% and 58% for the other three criteria. In the histopathological findings, 25 % of neck dissections were N+ when only one pattern had been detected on CT, whereas those neck sides in which four patterns were identified simultaneously showed regional spread in 100%. Conclusions The presence of specific morphological imaging criteria for head and neck tumours in cervical lymph nodes and their concomitance increase the accuracy of imaging to predict regional spread.

    ABSTRACT: Basal cell adenocarcinoma is a rare tumor first considered to be a separate entity by the WHO in 1991. The mean age of presentation is 48 years and it does not affect one gender more than the other. It normally follows an insidious course with nonspecific signs and symptoms. We present a case of adenocarcinoma of the lacrimal sac diagnosed at histological study. We show the CT, MRI, and histological findings. We discuss the differential diagnosis and treatment for this tumor.

    ABSTRACT: To review the petrous bone fractures during the last five years (1999-2004) in our hospital, its manage, control, and analysis onf the associated factors. To analyse the managing protocoles and current bibliography. We review 266 temporal bone fractures, 74 with petrous bone association. We analyse these fractures by sex distribution, injurie severity, otorhinolaryngological clinical findings, production mechanism and radiological findings. The cases are discussed and compared with current bibliography. Petrous bone fractures must be always suspected in patients with head trauma, specially if it associates severity and otorrhagia. It is necessary a deep colaboration between neurosurgeons, radiologists and otorhinolaryngologists to obtain a good management, control and follow up of the patients.
