Abstract

BADEMCI, G.; KENDI, T.  and  AGALAR, F.. Persistent metopic suture can mimic the skull fractures in the emergency setting?. Neurocirugía [online]. 2007, vol.18, n.3, pp.238-240. ISSN 1130-1473.

Metopism is partially or totally persisting suture extending from the nasion to the anterior angle of the bregma. The time of physiological closure of the meto- pic suture varies from birth to 8 years of age. Widely accepted closuring time is approximated at 2 years of age. Although formerly reported skull studies mentioned the persistent metopic suture, it is extremely rare in clinical practice. We presented a trauma case of 43 years of age who was demonstrated radiologically to have a persisting suture. Persistent metopic suture may be misdiagnosed as a vertical traumatic skull fracture extending in the mid-line in head trauma patients. Therefore the surgeon should be aware of this anatomical condition in the primary and secondary surveillance of the traumatized patient and during surgical intervention including especially frontal craniotomy. Reconstructed tomography scan demonstrating sutural closuring status may provide additional informative value in the diagnostic sequence superior to plain X-ray in the emergency setting.
