Chronic subdural hematoma diagnosis

• CT Scan: hypodense or mixed-density crescent-shaped collection
• MRI: better characterization of chronicity and membranes
• Often bilateral and may cause midline shift

Its clinical symptomatology often debuting with memory and attention disorders, so that the patient is usually referred to psychiatrists or neurologists, only a paraclinical investigation (CT scan or MRI) being able to establish the diagnosis. Even the appearance of the lateral signs is subjected to many diagnosis confusions because patients deny the existence of a trauma in over 50% of the cases ¹⁾.

MR imaging is more sensitive than CT in determining the size and internal structures of chronic subdural hematomas ²⁾.
