A lobar hemorrhage is a form of intracerebral hemorrhage involving one of the cerebral lobes.
Etiology
A common cause of lobar hemorrhage is Cerebral amyloid angiopathy in older patients. Neurological symptoms vary depending on the location of the hemorrhage[^1] [^2]:
<b>Frontal lobe:</b> Contralateral hemiparesis, typically affecting the arm, with mild involvement of the face and leg.
<b>Parietal lobe</b>: Contralateral hemisensory deficit and mild Hemiparesis.
<b>Occipital lobe</b>: Ipsilateral eye pain and contralateral homonymous hemianopia; the superior quadrant may be spared.
<b>Temporal lobe</b>: In a hemorrhage on the dominant side, Aphasia is the primary clinical presentation.
