Ultrasound-guided diagnosis on a parapharyngeal mass

Abstract

Masses in the parapharyngeal area are rare and often due to infectious phenomena arising from the oral cavity or pharynx which lead to abscess formation. Less frequently, the lesion can be neoplastic. Tumours of the parapharyngeal space are rare, accounting for less than 1% of all head and neck neoplasms. We report the case of a patient who came to our observation for mandibular pain. Multiparametric diagnostic imaging was done thus showing a parapharyngeal mass. An ultrasound guided biopsy was performed by a transcutaneous route with a high median approach at neck level, to characterize the mass in the right tonsillar region. The histological examination reported the final histological diagnosis of sarcomatoid carcinoma.

The efficacy of hyaluronic acid fragments with amino acid in combating facial skin aging: an ultrasound and histological study

“…Alexander and Miller in 1979 used a one-dimensional 15 MHz device to measure skin thickness [15]. Today higher frequency machines have been developed, with the goal of improving resolution and seeing surface features even at shorter wavelengths [16]. US have been increasingly adopted in various areas of medicine due to painlessness and cost-effectiveness.…”
