1)To demonstrate imaging findings in non-traumatic pathologies that result in intracerebral hemorrhage.
2)To distinguish primary from secondary causes of intracerebral hemorrhage based on imaging findings
3)Topropose an imaging approach to non-traumatic intracerebral hemorrhage
- Non-traumatic intracranial hemorrhage accounts for approximately 10% to15% of strokes inNorth America.
- Patients usually present with sudden onset focal neurologic deficit accompanied by headache,
alteration in the level of consciousness,
nausea and/or vomiting
• Parenchymal (common)
• Extradural (rare)
- Plain CT is theinitial imaging modality of choice.
- Acute hemorrhage appears hyper dense on plain CT.
- Often performed usually after CT to assess cause of hemorrhage...
Findings and procedure details
METHODS AND RESULTS: (Fig 3&4)
We retrospectively reviewed cases of non-traumatic cerebral hemorrhage from the PACS from July 2010-June 2013 (n = 65; 33 women,
median age at diagnosis 65 years [range 18-95 years].
Inclusion criteria included only those patients with proven etiologies for the hemorrhage.
We evaluated the clinical presentation and etiology of the hemorrhage based on multimodality imaging findings.
Sudden onset focal neurologic deficit was the most common presentation (n=40).
In 15 cases headache with nausea and vomiting...
excellent co-ordination between the radiologist and clinician forms the key to determine cause of most spontaneous Intra cerebral hemorrhage,
although in some patients the cause remains indeterminate
