Orbital Cellulitis or Orbital metastasis? A case report

Orbital cellulitis is an infectious condition however, noninfectious diseases such as malignancies may present with similar clinical findings. We present the case of a 67-year-old male with a prior history of mammary carcinoma who presented with right-sided palpebral edema, painful ocular movements, visual impairment, and proptosis, initially suggestive of orbital cellulitis. Despite intravenous antibiotic therapy, no clinical improvement was observed. MRI revealed an infiltrative orbital mass and later biopsy confirmed orbital metastasis from mammary carcinoma. This case highlights the importance of considering orbital metastasis in the differential diagnosis of orbital cellulitis, particularly in patients with a prior history of malignancy and atypical clinical evolution.
