Transorbital penetrating injury is relatively uncommon. Injury may be initially asymptomatic, but serious events can occur several days, months, or even years after the injury. A 25-month-old male presented with transorbital penetrating injury caused by a ice-cream wooden stick. Initial computed tomography (CT) of the head demonstrated acute subdural hematoma in right frontoparietal lobe with impinged bone fragments and surgical intervention was performed. Postoperative magnetic resonance (MR) imaging taken at 2 weeks after initial operation revealed an abscess cavity in the right frontal lobe, and it was naturally drained from previous supraorbital wound through transorbital fistula. Follow up MR imaging revealed slight decreased size of abscess cavity but there was no further improvement. The abscess was removed by open craniotomy, then the patient discharged without neurological deficit.
