summary/abstract:

Localised nasopharyngeal amyloidosis is rare. Findings on physical examination and invasive pattern on CT scan can be misleading as it can resemble nasopharyngeal carcinoma. A 64-year-old man presented with left aural fullness for 6 months. The physical examination showed straw-coloured fluid in the left middle ear and irregular reddish mass at the left side of the nasopharynx.
 

The CT scan showed a lobulated heterogeneous mass at the left side of the nasopharynx involving the left Eustachian tube opening. Pathology report was amyloidosis, thus, surgery was done. After a year, there were new foci of amyloidosis at the right side of the nasopharynx, and a repeat surgery was performed. Two years later, the systemic amyloidosis with underlying IgG4-related disease was suspected due to multiple organ involvement. Surgery is the treatment for localised amyloidosis with compressive symptoms. Close follow-up is important after surgical excision due to its recurrence and progression to systemic amyloidosis.
