Feb 14, 2025 · Nasopharyngeal carcinomas (NPC) are the most common primary malignancy of the nasopharynx. They are of squamous cell origin. Some types are strongly associated with the Epstein-Barr virus (EBV).

Nov 23, 2012 · CT has long been used for staging NPC, especially for the detection of skull base tumor involvement with lytic or sclerotic lesions [6, 7], but it has now largely been replaced by MRI for primary and nodal staging.

Mar 23, 2025 · Nasopharyngeal cancer staging refers to TNM staging of malignant tumors of the nasopharynx. The vast majority of applicable tumors are nasopharyngeal carcinomas, but other epithelial malignancies of the nasopharynx are included, such as minor salivary gland tumors.

This article reviews the MRI and CT of nasopharyngeal carcinoma. Ex-tension of nasopharyngeal tumors, especially into the skull base and the deep facial spaces, is well illustrated on imaging. Assessment of retropharyngeal and cervical lymphadenopa-thy is important for treatment planning. MRI is commonly used for monitoring patients af-ter therapy.

Mar 15, 2024 · The nasopharynx is readily accessible for biopsy via endoscopic, trans-nasal routes. If cervical metastases are easily palpable or visualized under ultrasound or CT guidance, they can also be biopsied via fine-needle aspiration.

Computed tomography (CT) scan. The CT scan is an x-ray test that makes detailed cross-sectional images of your body. A CT scan of the head and neck can provide information about the size, shape, and position of a tumor, see if it's growing into nearby tissues, and can help find enlarged lymph nodes that might contain cancer.

Mar 20, 2016 · Axial contrast-enhanced CT images (a, b and c) demonstrate the common imaging appearance of NPC as a mass centered at the lateral nasopharyngeal recess (fossa of Rosenmüller) (star in a) with pathological retropharyngeal adenopathy (arrow in b).

We compared the capacity of CT and MRI in assessing the extent of NPC in 67 patients. MRI was superior to CT in demonstrating lesions in the retropharyngeal node, skull base, intracranial area, carotid space, longus colli muscle and levator palatini muscle.

Feb 28, 2022 · Thin-section axial and coronal CT scans are sensitive for early cortical invasion; however, an increasing body of evidence suggests that MRI has several advantages over CT in the depiction of...

Apr 1, 2020 · Our knowledge of nasopharyngeal carcinoma (NPC) is rapidly changing. This article is a snapshot of the present state of NPC imaging in relation to the latest staging system, current standards of care, and treatment complications.
