The density of a hematoma on a non‐contrast computed tomography of the brain is determined by the degree of clot retraction, hematocrit and globin content. Classically, the appearance of an intracranial haemorrhage on a computed tomography correlates with the temporal evolution of hematoma. However, this case illustrates there are circumstances that this classical temporal appearance may not hold true.
