One-third of schwannomas occur in head and neck region, mostly in the parapharyngeal region. Cystic change is seen in only 4% of schwannomas. The diagnosis of such tumors remains a challenge due to the rarity of these lesions and limited utility of fine needle aspiration cytology. When cystic, branchial cleft cyst is an important differential diagnosis more so due to radiological resemblance. W...

We performed percutaneous CT-guided needle biopsies with a transfacial approach in the diagnosis of lesions of the parapharyngeal region. Via the buccal space, core needle biopsy specimens were obtained in eight patients with known parapharyngeal abnormalities identified by CT and/or MR imaging. In all cases, sufficient tissue was obtained to provide a definitive histologic diagnosis. There wer...

Introduction. De novo pleomorphic adenomas in the parapharyngeal space are rare and cause difficulties in its surgical management. We report the largest de novo pleomorphic adenoma arising from the parapharyngeal space and discuss its surgical management. Presentation of Case. A 34-year-old male presented with a giant de novo pleomorphic adenoma arising from the parapharyngeal space, which was ...

We report the MR imaging findings of a solitary fibrous tumor involving the parapharyngeal space. The tumor was a well-circumscribed solid mass with a lobulated contour. It had the same signal intensity as the muscle on T1-weighted MR images, heterogeneously high signal intensity on T2-weighted images, and homogeneous strong enhancement after the administration of contrast material. It mimicked...

nasopharyngeal angiofibroma is a relatively uncommon vascular tumor affecting adolescent males and it characteristically originates in the posterior lateral wall of the nasopharynx. primary extra-nasopharyngeal angiofibroma is very rare. here, i present a case of angiofibroma of the parapharyngeal space in a 53-year-old woman with ct and sonographic findings.

Neonatal stridor resulting from intrinsic or extrinsic aberration in the upper respiratory tract often poses not only a diagnostic problem, but also a difficult airway and a dilemma as to the necessity / timing of surgical intervention. A 45 day old female child with increasing stridor since birth was managed by emergency intubation and CT scan followed by excision biopsy of the cystic left sid...

Retropharyngeal lipomas are rare tumours that are usually asymptomatic until they reach a large size. The definitive treatment is surgical excision. Since the tumours are typically large at the time of presentation, extensive surgery for complete clearance of the lipoma from the retropharyngeal and parapharyngeal regions is to be expected. Transoral excision is typically indicated for small ret...

The da Vinci surgical robot has been used for minimally invasive surgery of the head and neck region including resection of tumors in the nasopharynx. Access to and vision of the nasopharynx with the robot are difficult. A pure transoral approach and midline palatal split approach have been described. The disadvantage of these approaches is the limited lateral access to the parapharyngeal space...

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...
