Intracerebral myiasis in a child

Area of Science:

• Neurology
• Parasitology
• Medical Entomology

Background:

• Hypoderma bovis, a botfly, typically infests cattle.
• Accidental human infections are rare but documented.
• Larval migration pathways into the human brain are not well understood.

Observation:

• A 6-year-old boy presented with clinical signs suggestive of an intracerebral event.
• Computed tomography (CT) revealed an intracerebral hematoma.
• Carotid angiography excluded vascular malformations as the cause.

Findings:

• The intracerebral hematoma was attributed to accidental human parasitism by Hypoderma bovis larvae.
• Standard neuroimaging techniques (CT, angiography) were insufficient for etiological diagnosis.
• Diagnosis was confirmed through seroimmunological tests and direct identification of the larva during surgery.

Implications:

• Highlights the potential for zoonotic transmission of Hypoderma bovis to humans.
• Underscores the limitations of neuroimaging in diagnosing rare parasitic brain infections.
• Emphasizes the importance of considering parasitological investigations in unexplained neurological cases.
