Post-traumatic Orbital Abscess in an Adult With No Evidence of Orbital Fracture, Paranasal Sinusitis, or Foreign Body Migration.

A 35-year-old man was hit against his left eye by his child's foot. Two days following trauma, the patient noticed diplopia in the upward and right gazes. On the first examination seven days after trauma, computed tomographic (CT) images revealed a small mass in the inferolateral orbit near the inferior orbital fissure. There was no radiological evidence of orbital fracture, paranasal sinusitis, or foreign body. Immediately after the first examination, the patient had a history of fever, retrobulbar pain, and nausea. These symptoms gradually worsened, and the patient visited the emergency department of our hospital at 13 days following trauma. CT images showed enlargement in the size of the mass. The diagnosis of the orbital abscess was made, and emergent drainage of the abscess was performed, followed by administration of intravenous antibiotics. On the fifth postoperative day, cultures of the abscess specimen showed growth of (4+), (4+), and (4+). The patient's condition improved significantly and at the 1.5-month follow-up, the patient did not have any symptoms related to the orbital abscess.
