Abstract

BACKGROUND:

Cranioplasty is a commonly performed procedure for the repair of cranial defects. Various materials have been used for this procedure and have a good safety profile. Human cerebral myiasis is an exceedingly rare condition. It involves the invasion of live or dead human tissues by larvae of the insect species dipterous.

CASE DESCRIPTION:

We describe the first case of cerebral myiasis associated with an artificial cranioplasty bone flap. There was delayed cerebral cortex infestation of the species dipterous after cranioplasty with polymethyl methacrylate bone flap. The patient initially presented with an acute subdural hematoma and contaminated, comminuted frontal bone fracture that required craniectomy with interval cranioplasty at 3 months. Two years after the index procedure, the patient presented for neurosurgical follow-up because of 2 months of nonhealing ulcers and a foul smell emanating from the cranioplasty site, as well as acute onset of unilateral arm and leg weakness. Surgical exploration found live larvae invading the dura and cerebral cortex, an area that was thoroughly debrided with good outcomes for the patient.

CONCLUSIONS:

Cerebral myiasis can be managed via surgical and antibiotic therapy to obtain a good clinical outcome.
