This article gives an overview about the main nasopharyngeal pathologies and incidental findings, which a radiologist could be confronted with in daily practice. These include nasopharyngeal cysts, lymphoid hyperplasia, juvenile angiofibroma, carcinomas and non-Hodgkin lymphoma. Typical radiological findings, possibilities for making a specific diagnosis, differential diagnosis and description of the spread of a neoplasm are the central points. Investigation techniques and clinical signs are briefly summarized.

Review Case Reports
[Penetrating gunshot wound in the neck. Case report and review of the literature].
Penetrating gunshot neck injuries present a serious challenge for the primary attending surgeon. By means of a case treated in the German Field Hospital in Mazar-e-Sharif (northern Afghanistan) and a review of the literature, the principles of diagnosis and treatment of penetrating zone II neck injuries due to gunshots or shrapnel are presented.

We present the case of a 44-year-old wrestler suffering from persistent bronchitis and chronic rhinosinusitis which had been refractory to therapy. The patient underwent extensive diagnostic examinations throughout the disease. Recently, at the age of 42 years otorhinological controls led to presentation at a cystic fibrosis (CF) centre where CF with the genotype Fdel508/3849+10 kb C-->T was diagnosed despite borderline sweat tests. Atypical CF should be considered in chronic persistent rhinosinusitis even in patients with borderline sweat tests.

The symptoms of a 52-year-old male patient of the university ENT out-patient department began with sudden headaches and itching neck followed by tingling in the mouth, problems with chewing and right-sided deviation of the tongue. In addition there was a history of nicotine use. MRI revealed an intraluminal increase in signal intensity in the right internal carotid artery. Isolated hypoglossal nerve palsy without participation of other cranial nerves is rare so that when headaches simultaneously occur, a dissection of the internal carotid artery is indicated, as in the case presented here.

Review Case Reports
[Significance of emissary veins in surgical treatment of temporal paragangliomas].
With the surgical removal of temporal paraganglioma, possible changes of the cerebral blood pathways of the Circle of Willis should be considered. If the cerebral blood drains dominates unilaterally and the pathway of drainage over the Bulbus venae jugularis is inadequate due to vessel malformation or variations or by intraluminal tumor growth, as for instance of temporal paragangliomas, collateral emissary vessels can take over this function by an extraordinary large lumen extension. ⋯ A presurgical angiography is, therefore, indicated. In case of vessel malformations or variations the use of computer-assisted surgery could be helpful to preserve such native emissary veins at the bony skull base, such as the condylar emissary vein in the case of a transcondylar infralabyrinthine approach.
