Metastasis of Breast Cancer to the Sphenoid Sinus Presenting as Tolosa-Hunt Syndrome

Metastatic Prostate Cancer Involving the Sphenoid Sinus and Mandible

Prostate cancer is the third most leading cause of cancer in men in the United States. Although expected metastatic spread to bone, liver, and lymph nodes are often monitored, there are other rare presentations that can occur. This case report demonstrates a rare presentation of prostate cancer spreading to the paranasal sinuses and orbit. Not only did this case have an atypical presentation mimicking infection, the diagnosis was also only achieved through pathological evaluation after an endoscopic examination and biopsy. This case demonstrates the importance of a low threshold for endoscopic examinations in uncertain sinonasal presentations, and consistent biopsies when performing endoscopic examinations.
