Stick a Needle in My Eye: A Case Report of Penetrating Needlefish Injury Causing Cavernous Sinus Thrombosis and Carotid Cavernous Fistula

Abstract

While swimming in the ocean on vacation in Cuba, a previously healthy 17-year-old female was unexpectedly stabbed through her orbit and into her brain by a needlefish. This is a unique case of a penetrating injury causing orbital cellulitis, retro-orbital abscess, cerebral venous sinus thrombosis and carotid cavernous fistula. After initial management at a local emergency department, she was transferred to a tertiary care trauma centre where she was treated by a team of emergency, neurosurgery, stroke neurology, ophthalmology, neuroradiology and infectious disease physicians. The patient faced a significant risk of a thrombotic event. There was careful consideration from the multidisciplinary team about the utility of thrombolysis or an interventional neuroradiology procedure. Ultimately, the patient was treated conservatively with intravenous antibiotics, low molecular weight heparin and observation. The patient continued to show clinical improvement several months later, which supported the challenging decision to opt for conservative management. There are very few cases to guide the treatment of this type of contaminated penetrating orbital and brain injury.
