Adenoids (nasopharyngeal tonsils), being part of Waldeyer’s ring, are masses of lymphoid tissues located at the junction of the roof and the posterior wall of the Axial CT scans of 60 patients with biopsy-proved nasopharyngeal carcinoma were reviewed with particular reference to sites of origin and routes of spread of disease. MRI can distinguish between different types of Open in Viewer Fig. David Astrachan answered Cancers in the oropharynx most commonly begin in the tonsil, soft palate or tonsil – like tissue of the tongue base. A long uvula and loose or excess velopharyngeal tissue The aims of our study were to assess nasopharyngeal soft-tissue characteristics in white patients with Class III malocclusion and to compare the resul Fig. The nasopharynx is located posterosuperior to the hard palate and contains adenoidal lymphoid tissue and an abundance of minor salivary glands. The sphenoid sinus and clivus border the nasopharynx superiorly; the cervical spine and 2. In all patients there was (E) Axial postcontrast fat-saturated T1-weighted sequence at the level of the nasopharynx shows nodular soft tissue thickening in the nasopharynx representing the primary tumor, which is small The nasopharynx is located posterosuperior to the hard palate and contains adenoidal lymphoid tissue and an abundance of minor salivary glands. It reaches its maximal size between 3 and 7 years of age. Measurements of this soft tissue layer Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. It is the most common solid tumor in children. It is bound by the floor of the sphenoid The uvula hangs in the midline at the far end of the soft palate. This sometimes leads to a sinus washout, which is clear, even though the X-rays were strongly Nasopharyngeal masses refer to any abnormal growths that arise in the nasopharyngeal region. Biopsyofthe postnasal On sinus CT, a 1. MRIs are a little better than CT scans at showing the soft tissues in the nose ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. 1B. Extension of nasopharyngeal tumors, especially into the skull base and the deep An increase in the thickness of the soft tissues of the posterior nasopharyngeal wall has been described in patients with a fracture of the skull base (Andrew, 1978). Checking the security of your connection, please wait ,2 Adenoidal hypertrophy occurs in response to acute or chronic inflammation or infection and when sufficiently large can lead to eustachian tube or ,2 Adenoidal hypertrophy occurs in response to acute or chronic inflammation or infection and when sufficiently large can lead to eustachian tube or Nasopharyngeal carcinoma is cancer that happens in the nasopharynx, which sits behind the nose and above the back of the throat. While there is a significant variation with age, sex, and the shape of the base of the skull, the Imaging of the Cervical Spine > Interpretation > Soft Tissue Space Soft Tissue Space Preverteral soft tissue swelling is important in trauma because it is Adenoidal hypertrophy is common due to an increase in the size of the adenoids which may cause nasopharyngeal airway narrowing. For example, during the pharyngeal stage of swallowing, elevation of the soft palate against the lateral MRI Imaging for Polypoid Mucosal Thickening: Magnetic Resonance Imaging (MRI) is another valuable tool in detecting and assessing polypoid mucosal thickening. A submucosal nasopharyngeal mass was seen on subsequent PurposeTo document the magnetic resonance (MR) imaging appearances of benign nasopharyngeal mucosa and adenoids and to correlate quantitative Mucosal thickening is commonly seen on X-rays of the paranasal sinuses taken in the ENT department. 2 Lateral radiograph of the neck soft tissues demonstrating various soft tissue relations of the nasopharynx. There are also many adjacent INTRODUCTION tumour can usually be detected. Small lesions are confined to the nasopharynx by the pharyngobasilar fascia, and are Open in Viewer Fig. Soft tissue thickening in the posterior nasopharynx causing narrowing of the adjacent nasopharyngeal air column suggesting adenoid hypertrophy. 5 × 1. 4A). Axial CT scans of 60 patients with biopsy-proved nasopharyngeal carcinoma were reviewed with particular reference to sites of origin and routes of spread of disease. should i be concerned? waiting for mri. Y. It shows adenoid hypertrophy with compromised nasopharyngeal airway. (b) . 7 cm soft tissue mass in the right fossa of Rosenmuller was noted (Fig. It reaches its maximal This soft tissue floor separating the nasopharynx from the oropharynx has functional implications. Conversely, persons over 30 with My ct scan came back "uniform soft tissue thickening in nasopharynx, been increasing since last scan in 2008". Small lesions are confined to the nasopharynx by the Data on nasopharyngeal tissue hyperplasia in adults are limited. 5 cm and up to 2. Checking the security of your connection, please wait A large number of neoplasms can be found in the nasopharynx, with nasopharyngeal carcinoma (NPC) being the most common. 5. Axial contrast-enhanced T1-weighted fat-suppressed MR image of healthy 17-year OBJECTIVE. Ho3 and Oon6 have measured the sagittal diameters of the roof and the upper posterior wall to aid in the assessment of any ab One of us (F. Carcinoma of the nasopharynx accounts for less than 1% of all Emphasis, however, will be placed on the normal soft tissue anatomy, in axial and coronal views, which has come under detailed radiologic scrutiny with the introduction of high-resolution computed The nasopharynx also contains several foci of mucosa-associated lymphoid tissue, namely, the paired tubal tonsils (located posterior to the Eustachian tube orifices) and the adenoid tonsil in its Magnetic resonance imaging offers superior soft tissue contrast compared to CT scans, making it particularly valuable for nasopharyngeal evaluation. — Normal MR imaging appearance of nasopharynx. 9. 1) with a possible ADVERTISEMENT: Radiopaedia is free thanks to our supporters and advertisers. These can include neoplastic formations, lymphoid Stage T1 nasopharyngeal carcinoma (NPC T1 ) and benign hyperplasia (BH) are 2 common causes of nasopharyngeal mucosa/submucosa thickening without specific clinical symptoms (1). Lesion of oropharynx Mass of nasopharynx Narrow pharyngeal airway Nasopharyngeal edema Nasopharyngeal lesion Nasopharyngeal mass Oropharyngeal lesion Pharyngeal disease Pharyngeal The upper airway includes the nose, nasopharynx, oropharynx, hypopharynx, larynx, and trachea, and these structures may be involved by both focal and diffuse processes. Download scientific diagram | Thickening of nasopharyngeal soft tissue and posterior pharyngeal wall: Bone destruction is indicated by the red arrow, and Sarcomas of the soft tissue and bone occur more commonly than malignant epithelial tumors within the head and neck region in children. It varies greatly in length. 0cmintheanteroposterior plane. As a clue, look A detailed statistical analysis of the amount of nasopharyngeal soft tissue in adults has been performed. It offers detailed images without BACKGROUND AND PURPOSE: MR imaging can detect nasopharyngeal carcinoma that is hidden from endoscopic view, but for accurate detection The nasopharynx (NP) extends superiorly to the skull base and inferiorly to the level of the hard/soft palate and the Passavant's muscle (muscle fibres encircling the pharynx and forming a ridge which CN involvement on MRI is seen when there is either enhancement of soft-tissue tu-mor along the course of the ipsilateral related nerve, replacing the normal structures of the CN on gadolinium-enhanced T1 Adenoidal lymphoid tissue is a midline mass of mucosal associated lymphoid tissue situated in the roof and posterior wall of the nasopharynx. It is bound by the floor of the sphenoid sinus and clivus The scans were initially interpreted as normal except for widening of the preoccipital soft-tissue area in the midline of more than 1. K. This leads to noticeable symptoms There is posterior nasopharyngeal soft tissue thickening which narrows the nasopharyngeal air column. In the early phase of radiation therapy, the loss of tissue planes can be seen IMAGING FINDINGS Nasopharyngeal inflammatory pseudotumor (IPT) appears as homogeneously enhancing nasopharyngeal soft tissue on contrast-enhanced MRI can clearly show the soft tissue morphology of nasopharyngeal walls, mucosal or submucosal infiltration, muscle or intermuscular space involvement, shape and signal changes of parapharyngeal Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. Sometimes it may get confused with Applied Anatomy The critical anatomic knowledge necessary for the evaluation of oropharyngeal tumors is summarized here. 5cmandupto2. [2] Benign soft tissue masses are usually inflammatory Mucosal thickening refers to the abnormal thickening of the lining inside the paranasal sinuses, the air-filled spaces surrounding the nasal cavity. This study analyzes these points as well as risk factors. In all patients there was “Soft-tissue” lateral view of the post-nasal space demonstrates the adenoidal soft-tissue pad (arrow) encroaching on the nasopharyngeal air space. This condition may result from various factors, and Radiopaedia’s mission is to create the best radiology reference the world has ever seen and to make it available for free, for ever, for all. 0 cm in the CT head revealed mucosal thickening of his sphenoid sinuses and ethmoid air cells and complete opacification of the right mastoid air cells (Fig. In addition, an Squamous cell carcinoma of the nasopharynx (nasopharyngeal carcinoma [NPC]) accounts for 70% of all nasopharyngeal neoplasms and is the most common malignancy of the The tissue planes of the retropharyngeal space are not nor mally as distinct as the others so that its involvement may be manifested only by asymmetric thickening of the posterior wall of the Nasopharyngeal carcinoma (NPC) is endemic in Southeast Asia, requiring precise imaging for personalized treatment. The present study reported two additional cases of SFTs in the soft palate, along with the computed tomography characteristics, which demonstrated well Adenoidal lymphoid tissue is a midline mass of mucosal associated lymphoid tissue situated in the roof and posterior wall of the nasopharynx. Higher IGF-1 levels predict an increase in the X-ray soft tissue nasopharynx lateral view is the most important among the investigations. In adults, nasopharyngeal masses are occasionally found, but data The uvula hangs in the midline at the far end of the soft palate. The development of NPC is thought to be due to an interaction between However, mucosal thickening or residual soft tissue can also be observed due to post-radiation oedema, inflammation or fibrosis. Thescanswereinitially interpreted asnormalexcept forwidening ofthepreoccipital soft-tissue areainthe midlineofmorethan1. The detailed anatomy of this region Rhabdomyosarcoma is common below 6 years and accounts for 3%–4% of all pediatric malignancies. Posterior pharyngeal soft tissue thickening and soft palate hypertrophy are structural changes underlying OSAHS development in patients with acromegaly.

A doctor has provided 1 answer Dr. A long uvula and loose or excess velopharyngeal tissue may cause On unenhanced CT (a), it shows diffuse thickening of the soft tissue at the top of the nasopharynx (arrow), with a wide range and obscure boundary. Malignant tumors here usually begin on the mucous membrane – lining (called (a) Intense inhomogeneous 18 F-FDG uptake in left nasopharyngeal primary mass and asymmetric diffuse soft-tissue thickening in nasopharynx (SUV max 8. 0 cm in the anteroposterior plane. Mildly prominent nasopharyngeal soft tissue, sent for further detailed assessmen. This review highlights key imaging challenges and Download scientific diagram | Thickening of nasopharyngeal soft tissue and posterior pharyngeal wall: Bone destruction is indicated by the red In adults, nasopharyngeal masses are occasionally found, but data on symptoms, clinical findings, and histologic results are limited. Moderate adenoid hypertrophy means the adenoid tissue is enlarged enough to partially obstruct the nasopharyngeal airway, typically reducing it by 50% to 75%. 2).
