Pharyngeal amyloidomas: Variable appearance on imaging.

Area of Science:

• Medicine
• Radiology
• Pathology

Background:

• Amyloidomas are uncommon tumoral deposits of misfolded proteins, associated with systemic amyloidosis or as isolated masses.
• Focal amyloidomas generally have a favorable prognosis, unlike systemic forms of amyloidosis.
• Accurate imaging identification of amyloidomas can guide diagnostic testing.

Observation:

• Head and neck amyloidomas exhibit variable imaging features, often appearing T2 hypointense to iso-slightly hyperintense compared to muscle.
• This study details two cases of pharyngeal submucosal amyloidomas with distinct imaging characteristics.
• The variable appearance underscores the diagnostic challenge these rare lesions present.

Findings:

• Amyloidomas can present with widely differing imaging appearances on diagnostic studies.
• The size and specific imaging characteristics of amyloidomas can vary significantly.
• Submucosal pharyngeal amyloidomas were observed in the presented cases.

Implications:

• Recognizing the diverse imaging spectrum of amyloidomas is crucial for radiologists and clinicians.
• Improved imaging recognition can lead to earlier and more accurate diagnosis of amyloidomas.
• Further research into the imaging of rare amyloidomas can enhance understanding and patient management.
