The patient had a hemorrhagic stroke due to basal ganglia hemorrhage. The clinical symptoms of contralateral hemiparesis are caused by the affection of the internal capsule. The factors Age (> 70 years) Known arterial hypertension Non-lobar location of hemorrhage in the basal ganglia suggest a hypertensive genesis of the intracerebral hemorrhage. Besides the basal ganglia, [...]

The patient incidentally had normal pressure hydrocephalus (NPH). In NPH, there is an expansion of the ventricular system without increased intracranial pressure. The typical triad (“Hakim's Triad”) of NPH consists of gait disturbance with a broad-based and short-stepped gait, congnitive impairment (ranging from mild to severe, i.e. dementia), and urinary incontinence. Diagnosis of NPH includes [...]

The patient had a traumatic SAH. The subarachnoid hemorrhage is a bleeding into the subarachnoid space, between the arachnoid and pia mater. The traumatic SAH is most commonly located frontal/frontobasal and temporal/temporobasal. A non-contrast CT follow-up was performed after 6 hours. CT angiography was not performed in the absence of space-occupying hemorrhage and clinical symptoms.

Clinical presentation: A 72-year-old patient is brought to the emergency room with a left-sided hemiparesis. The symptoms occurred about 5 hours ago. Pre-existing conditions: Arterial hypertension, Type 2 diabetes mellitus Question: Intracranial hemorrhage? Infarct? A non-contrast CT was performed.

A - Intraparenchymal hemorrhage in the right basal gangliaB - Perifocal edemaC - Slight midline shift to the leftD - Post-ischemic defect in the right caudate nucleusE - Confluent microangiopathy in the centrum semiovale on both sides (Fazekas Grade 3) Here is a summary of the expert findings:

Clinical presentation: A 40-year-old female patient presents to the emergency room with a treatment-resistant headache. She has never experienced such severe headaches before, and various analgesics have not provided relief. Question: Cause of the symptoms? A non-contrast CT was performed.
