The current study presents a rare case of osteoblastic osteosarcoma arising from an extremely rare site, namely, the parapharyngeal space. To the best of our knowledge, this is the first study of computed tomography (CT) and magnetic resonance imaging (MRI) of an osteosarcoma in the parapharyngeal space with pathological correlation. A 56-year-old male presented with a mass of the right facial ...

The parapharyngeal space is an anatomic region that may present various forms of tumoral masses, different by histology, extension and location. For ENT aeromedical examinator, deciding the most proper surgical approach in this treatment may be difficult. The authors analyze diagnostic and treatment criteria used for parapharyngeal space tumors and review the surgical techniques used. Transcerv...

OBJECTIVES/HYPOTHESIS A subtemporal preauricular approach to the infratemporal fossa and parapharyngeal space has been the traditional path to tumors of this region. The morbidity associated with this procedure has lead to the pursuit of less invasive techniques. Endoscopic access using a minimally invasive transmaxillary/transpterygoid approach potentially may obviate the drawbacks associated ...

Parapharyngeal space (PPS) tumours, most of them benign, account for some 0.5% of tumours of the head and neck. The importance of these tumours lies mainly in two aspects: on the one hand, the difficulty of early diagnosis, due to the lack of symptoms in the initial stages and, on the other, the extreme complications of performing surgery in the parapharyngeal region. This article discusses two...

BACKGROUND The metastasis of papillary thyroid carcinoma to the parapharyngeal space is rare and discussed in the English literature before. Encountering a parapharyngeal mass with cystic appearance on imaging, one should rule out thyroid malignancy as differential diagnosis. CASE PRESENTATION The case presented here is a 22-year-old woman who was referred to our clinic with complaints of pai...

We report 2 unusual cases of hypervascular masses in the parapharyngeal space. The first case involved a poorly differentiated metastatic carcinoma of oropharyngeal origin that mimicked a carotid body tumor. The second case involved a highly vascular myoepithelioma located in the parapharyngeal space.

Fig, 1,-25-year-old man with parapharyngeal angiofibroma. A, Unenhanced axial CT scan shows a mass (arrows) in parapharyngeal space, with anterior displacement and splaying of pterygoid plates. B, Enhanced coronal CT scan shows an enhancing left-sided parapharyngeal mass (arrows) displacing pharynx toward right. C, Angiogram of left common carotid artery shows a hypervascular mass (arrows) supp...

INTRODUCTION Tumours of the parapharyngeal space are rare. Only 0.5% of head and neck tumours occur in this space. Surgical excision of parapharyngeal space lesions is challenging because of the anatomical complexity of the area. PRESENTATION OF CASE A 31-year-old male patient was referred by his general dental practitioner for removal of lower wisdom teeth due to multiple episodes of pericor...

Parapharyngeal space masses account for 0.5% of all head and neck neoplasms. Pleomorphic adenoma arising from the epithelial rests of the salivary tissue in the parapharyngeal space is rare. Computed tomography (CT) and Magnetic Resonance Imaging (MRI) allows a precise topographical localization of the mass and the diagnosis of its nature in the majority of cases. Treatment of parapharyngeal pl...
