Abstract:
A 72-year-old man presented with a slowly progressive left hyperglobus, left infraduction deficit, bilateral lower eyelid retraction, and dysphagia. He had a notable chin-down head position, diplopia in primary position, and 3 mm of left proptosis. He had been diagnosed with Graves disease 3 years before presentation. CT scans showed enlargement of the left inferior and medial rectus muscles with associated stranding of the retrobulbar fat and a low-density heterogeneous mass in the left aspect of the neck protruding in the nasopharynx. Biopsies of the orbit and nasopharynx revealed focal areas of amyloid. This represents the first report of bifocal amyloidomas of the orbit and nasopharynx.
