Presentation
Elderly patient. Left sided weakness. No history of fall. Clinically assumed stroke.
Patient Data
Near isodense large left sided subdural hematoma with ventricular effacement and midline shift. Thin, more hyperdense parafalcine hematoma close to the vertex.
Background atrophy change.
Note how the collection follows the dural reflections, up against the falx, as well as crosses the coronal suture; all features that this is a subdural rather than extra-dural collection.
Case Discussion
Subdural hematomas are one of the potential 'stroke mimics' in the elderly.
This isodense hematoma is likely 7 days or more in age, with the atrophic brain 'accomodating' the hematoma prior to presentation.
