Acinic cell carcinoma (AciCC) is a low-grade malignancy which rarely metastasizes to bone or cavernous sinuses. A 62-year-old male patient, previously treated for AciCC of right parotid with surgery and local radiotherapy, presented 10 years later with progressive visual impairment and restriction of ocular movements. Magnetic resonance imaging of the head and orbit showed an expansile lobulated mass with heterogeneous signal intensity in bilateral cavernous sinus with encasement of the internal carotid artery on both sides. Fluorodeoxyglucose positron emission tomography/computed tomography showed multiple lytic lesions with increased uptake in the left clavicle (with soft tissue component), sternum, multiple cervico-dorso-lumbar vertebrae, and ribs. Biopsy from the clavicular lesion showed AciCC. He was treated with palliative radiotherapy to cavernous sinuses and other metastatic site followed by palliative chemotherapy with six cycles of paclitaxel and carboplatin. He had a partial response to palliative treatment and had good symptomatic relief at 12 months of follow-up.
