Bone Scan With SPECT/CT Demonstrated Phthisis Bulbi

Abstract

Abstract A 46-year-old man has a history of right eye vision loss from childhood due to an injury, right hypopharyngeal cancer with metastasis to right neck lymph nodes treated with concurrent chemoradiotherapy, and left tonsillar cancer after resection and adjuvant chemotherapy. Whole-body bone scan showed abnormal uptake to the right eye region, whereas SPECT/CT imaging localized this uptake to sharply defined, round to oval bone density foci of calcium scattered in the sclera and surrounding tissues, indicative of phthisis bulbi with posttraumatic calcification. Phthisis bulbi represents a shrunken ocular globe with calcification or ossification, typically as a sequela of trauma.
