Unusual MR and CT findings of an inflammatory pseudotumor in the parapharyngeal space of a 73-year-old woman are reported. The mass was hypointense on T1- and T2-weighted images and demonstrated ring enhancement after contrast medium injection. Punctated calcifications were scattered at the periphery. Inflammatory pseudotumors in the parapharyngeal space are rare, and only three cases have been...

Methods: The da Vinci Robotic Surgical System (Si) was used for complete resection of four skull base tumors. Two pleomorphic adenomas in the parapharyngeal space, one pleomorphic adenoma in the infratemporal fossa and one metastatic papillary thyroid cancer node in the high retropharyneal nodal basin were resected. A transpalatal approach was used to access the infratemporal fossa (n=1) and re...

Background. Parapharyngeal space is one of potential facial planes for neoplasms and infections and represents less than 1% of all head and neck tumours. Occurrence of the pleomorphic adenoma in the parapharyngeal space is a rarity. Case Presentation. Here, three giant pleomorphic adenomas of different sizes occupying the parapharyngeal space in three patients are reported. Extensive preoperati...

Tumors of the parapharyngeal space are rare accounting approximately for 0.5% of all head and neck tumors. In the retrostyloid space, schwannomas are a more common finding, in contrast to other tumors. Usually, they present with a variety of slight symptoms until they grow in size and compress surrounding organs. Surgical treatment of parapharyngeal space tumors is difficult; due to the anatomi...

Parapharyngeal tumors are less common in clinical practice and are often difficult to diagnose upon clinical examination due to the anatomic complexity of the region. We report a rare case of extracranial parapharyngeal space meningioma presenting as a cervical mass with encasement of cranial nerves giving tram track appearance and features on various imaging modalities [Radiographs, Ultrasound...

The clear cell sarcoma of tendons and aponeuroses (CCSTA) is a rare soft tissue sarcoma in the head and neck region and parapharyngeal space. Over 95% of CCSTAs present in the extremities, with the head and neck region (1.9%) being an unusual site. This study presents an additional case of CCSTA of the head and neck region involving the parapharyngeal space in a 48-year-old men and review of th...

OBJECTIVE To validate the hypothesis that fat tissue accumulation adjacent to the upper airway contributes to a predisposition to obstructive sleep apnea (OSA), irrespective of body mass index (BMI), as well as investigate the effect of the volume of fat tissue on pharyngeal mechanical loads. METHODS Fourteen subjects and 14 controls were enrolled in this study. Pharyngeal anatomy (the fat t...

Parapharyngeal ganglioneuroma is a rare benign tumor, with fewer than 40 cases having been reported in the literature. We report a case of parapharyngeal ganglioneuroma in a child, including the presentation, diagnostic testing, treatment, outcome and a review of the literature. The patient presented with a large cervical mass arising from the cervical sympathetic chain. Complete excision of th...

BACKGROUND Wegener's Granulomatosis (WG) is classically characterized by the triad of sinonasal, pulmonary, and renal manifestations. However, a growing body of research has demonstrated that atypical head and neck pathologies including retropharyngeal and parapharyngeal lesions are often the presenting feature of patients found to have WG. CASE This report describes the hospital course of a ...
