Brain Hemorrhage Flashcards
HAs, poor concentration, periodic memory lapses. Sometimes fine, but other times sleepy and “out of it.”
Chronic Subdural hematoma
Presents w/o focal neuro sxs
+Fluctuating mental status changes
chronic subdural hematoma
Hypodense to isodense collection of dried blood over the cortex on CT or MRI.
chronic subdural hematoma
EEG - Slow, high voltage waves
chronic subdural hematoma
Convex hyperdensity outside brain tissue
Epidural
Epidural usually in this location
Parietotemporal
Crescent shaped hyperintensity between brain and skull on CT scan
Subdural
Trauma to bridging veins between inner and outer meningeal membranes
Subdural
Severe HA and vomiting. Dull pain, occipital region, worse w/ lying down. Neuro exam wnl, except for severe BL papilledema.
LP - opening pressure 80 w/ normal CSF chemistry and 120 RBCs in tube.
D-dimer and fibrinogen degradation product in serum are elevated.
Head CT w/o contrast - wnl
Head CT w/ contrast - “empty delta sign” on axial images
Dx?
Sagittal sinus thrombosis
HA, vomiting, BL papilledema, intracranial HTN
Sagittal sinus thrombosis
Head CT w/ contrast - “empty delta sign” on axial images
Sagittal sinus thrombosis
MVA and closed head injury w/o LOC. Initially alert, oriented and coherent, w/ normal behavior. But 20 mins later - turns pale and falls to ground unconscious. 5 mins later - conscious and behaving normally
Cause?
Vasovagal syncopal attack
Sudden severe HA, vomiting, collapse, relative preservation of consciousness, few or no lateralizing neuro signs, and neck stiffness.
Dx?
Subarachnoid hemorrhage
Most common cause of subarachnoid
head trauma
Most common cause of non-traumatic subarachnoid
berry aneurysm (saccular)
