Cortical Laminar Necrosis Caused by Critically Increased Intracranial Pressure in an Infant

A 3-month-old boy presented with critically elevated intracranial pressure (ICP) due to bilateral subdural hematomas, which resulted in diffuse cortical laminar necrosis, manifesting as a 1-week history of appetite loss, fever, and intermittent seizure. Initial computed tomography revealed bilateral subdural fluid collections. Burr hole drainage was carried out to control the ICP. T-1-weighted magnetic resonance imaging on day 26 revealed diffuse linear hyperintense lesions, which suggested cortical laminar necrosis. This is an extremely unusual case of cortical laminar necrosis caused by elevated ICP due to subdural hematoma in an infant.
