Sinonasal Carcinoma Presenting with Proptosis and Visual Impairment: A Case Report.

ABSTRACT

Sinonasal carcinoma is a rare but aggressive malignancy arising from the nasal cavity and paranasal sinuses. We present a case of a 40-year-old female who presented with a three-month history of headache, diminution of vision, and proptosis. Imaging studies revealed soft tissue density with bony erosion and extraconal extension in the left orbit. Histopathological examination confirmed sinonasal carcinoma with anaplastic changes. The patient underwent surgical excision of the tumor and received post-operative care in the neuro-ICU. Her visual acuity improved post-surgery, and she was discharged with stable neurological status. This case highlights the challenges in the diagnosis and management of sinonasal carcinoma and underscores the importance of multidisciplinary care for optimal outcomes. Early diagnosis and intervention are crucial in preventing complications and achieving favorable outcomes in patients with this aggressive malignancy.
