RESUMEN
We present a case of post-traumatic hematoma developing between the 2 layers of the cranial dura in a 2-year-old child following head injury. This child presented with history of fall from a height in altered sensorium with paucity of movements on the left side. Computerized tomography scan of the brain showed a right parietal linear fracture with an underlying hyperdense biconvex hematoma. Emergency evacuation of the hematoma was done. On elevation of the scalp flap, a fibrous membrane was seen protruding between the fracture lines. Following craniotomy, the hematoma was identified between the 2 layers of the dura and the fibrous membrane that protruded between the fracture lines was identified as the endosteal layer of dura. The hematoma was evacuated after opening the outer endosteal layer. After evacuation of the hematoma, the endosteal and meningeal layers could be identified separately and the point where these 2 layers split to enclose the hematoma was identified at the outer border of the hematoma. The child had no neurological sequel at the time of discharge.
