====== Unilateral chronic subdural hematoma ======

Patients with unilateral [[chronic subdural hematoma]] had a more frequent occurrence of [[hemiparesis]] than the patients with [[bilateral chronic subdural hematoma]]. It took the left-sided chronic subdural hematomas less time (about 200 hours earlier) than the right-sided ones to present their symptoms although the average hematoma diameter value was almost the same.

[[Extraaxial]] collection located in the right frontoparietal [[convexity]] with minimal extension towards the [[temporal region]].
It shows a serohematic level in its most cranial and posterior portion and [[hyperdense]] content in the most inferior portion at the frontal level, suggesting a subacute evolution with signs of recent [[rebleeding]]. It presents a maximum thickness of 2.8 cm and causes a notable mass effect with the collapse of the adjacent sulci of convexity and of the right [[lateral ventricle]], and with a midline displacement of approximately 8 mm.
