Intrasinus Wood Foreign Body Causing Orbital Cellulitis in Congenital Insensitivity to Pain with Anhidrosis Syndrome

A 2-year-old boy with congenital insensitivity to pain with anhidrosis (CIPA) was referred with a 2-day history of left periorbital swelling and mucoid conjunctival discharge. Marked worsening was noted despite intramuscular ceftriaxone treatment for 3 days, with marked proptosis, conjunctival chemosis, and a frozen eye. Orbital cellulitis was suspected. Ceftriaxone was intravenously administered. Orbital computed tomography (CT) disclosed an inflammatory process in the medial aspect of the left orbit with ethmoiditis. Improvement was not noted after external ethmoidectomy and drainage of the intraconal abscess. Repeat CT showed a recurrent intraconal abscess. A revision external ethmoidectomy was performed, and a bent wooden match was removed from the posterior aspect of the ethmoidal sinus, after which significant clinical improvement was noted. In patients with CIPA, accidental or self-penetrated foreign bodies must be kept in mind when treating all types of wounds.
